.\"SKIP_SECTION"
|
|
.SH NAME
|
|
bochsrc \- Configuration file for Bochs.
|
|
.\"SKIP_SECTION"
|
|
.SH DESCRIPTION
|
|
.LP
|
|
Bochsrc is the configuration file that specifies
|
|
where Bochs should look for disk images, how the Bochs
|
|
emulation layer should work, etc. The syntax used
|
|
for bochsrc can also be used as command line arguments
|
|
for Bochs. The .bochsrc file should be placed either in
|
|
the current directory before running Bochs or in your
|
|
home directory.
|
|
|
|
Starting with Bochs 1.3, you can use environment variables in
|
|
the bochsrc file, for example:
|
|
|
|
diskc: file="$IMAGES/30M.sample", cyl=615, heads=6, spt=17
|
|
|
|
Starting with version 2.0, two environment variables have a built-in
|
|
default value which is set at compile time. $BXSHARE points to the
|
|
"share" directory which is typically /usr/local/share/bochs on UNIX
|
|
machines. See the $(sharedir) variable in the Makefile for the exact
|
|
value. $BXSHARE is used by disk images to locate the directory where
|
|
the BIOS images and keymaps can be found. If $BXSHARE is not defined, Bochs
|
|
will supply the default value. Also, $LTDL_LIBRARY_PATH points to a list of
|
|
directories (separated by colons if more than one) to search in for Bochs
|
|
plugins. A compile-time default is provided if this variable is not defined
|
|
by the user.
|
|

.SH OPTIONS
|
|
|
|
.TP
|
|
.I "#include"
|
|
This option includes another configuration file. It is
|
|
possible to put installation defaults in a global config
|
|
file (e.g. location of rom images).
|
|
|
|
Example:
|
|
#include /etc/bochsrc
|
|
|
|
.TP
|
|
.I "config_interface:"
|
|
The configuration interface is a series of menus or dialog boxes that
|
|
allows you to change all the settings that control Bochs's behavior.
|
|
There are two choices of configuration interface: a text mode version
|
|
called "textconfig" and a graphical version called "wx". The text
|
|
mode version uses stdin/stdout and is always compiled in. The graphical
|
|
version is only available when you use "--with-wx" on the configure
|
|
command. If you do not write a config_interface line, Bochs will
|
|
choose a default for you.
|
|
|
|
.B NOTE:
|
|
if you use the "wx" configuration interface, you must also use
|
|
the "wx" display library.
|
|
|
|
Example:
|
|
config_interface: textconfig
|
|
|
|
.TP
|
|
.I "display_library:"
|
|
The display library is the code that displays the Bochs VGA screen. Bochs
|
|
has a selection of about 10 different display library implementations for
|
|
different platforms. If you run configure with multiple --with-* options,
|
|
the display_library command lets you choose which one you want to run with.
|
|
If you do not write a display_library line, Bochs will choose a default for
|
|
you.
|
|
|
|
The choices are:
|
|
x X windows interface, cross platform
|
|
win32 native win32 libraries
|
|
carbon Carbon library (for MacOS X)
|
|
beos native BeOS libraries
|
|
macintosh MacOS pre-10
|
|
amigaos native AmigaOS libraries
|
|
sdl SDL library, cross platform
|
|
term text only, uses curses/ncurses library, cross platform
|
|
rfb provides an interface to AT&T's VNC viewer, cross platform
|
|
wx wxWindows library, cross platform
|
|
nogui no display at all
|
|
|
|
.B NOTE:
|
|
if you use the "wx" configuration interface, you must also use
|
|
the "wx" display library.
|
|
|
|
Example:
|
|
display_library: x
|
|
|
|
.TP
|
|
.I "romimage:"
|
|
You need to load a ROM BIOS into F0000-FFFFF. The BIOS controls
|
|
what the PC does when it first powers on. Normally, you can use a
|
|
precompiled BIOS in the
|
|
.B bios/
|
|
directory of the source tree, named BIOS-bochs-latest. You can also use
|
|
the environment variable $BXSHARE to specify the location of the BIOS.
|
|
|
|
Examples:
|
|
romimage: file=bios/BIOS-bochs-latest, address=0xf0000
|
|
romimage: file=$BXSHARE/BIOS-bochs-latest, address=0xf0000
|
|
|
|
.TP
|
|
.I "megs:"
|
|
Set this to the default number of Megabytes of
|
|
memory you want to emulate. You may also pass
|
|
the
|
|
.B 'megs:N'
|
|
option to bochs. The default
|
|
is 32MB, since most OS's won't need more than
|
|
that.
|
|
|
|
Example:
|
|
megs: 32
|
|
|
|
.TP
|
|
.I "optromimage1: \fP, \fIoptromimage2: \fP, \fIoptromimage3: \fPor \fIoptromimage4:"
|
|
You may now load up to 4 optional ROM images. Be sure to use a
|
|
read-only area, typically between C8000 and EFFFF. These optional
|
|
ROM images should not overwrite the rombios (located at
|
|
F0000-FFFFF) and the videobios (located at C0000-C7FFF).
|
|
Those ROM images will be initialized by the bios if they contain
|
|
the right signature (0x55AA).
|
|
It can also be a convenient way to upload some arbitary code/data
|
|
in the simulation, that can be retrieved by the boot loader
|
|
|
|
Example:
|
|
optromimage1: file=optionalrom.bin, address=0xd0000
|
|
|
|
.TP
|
|
.I "vgaromimage:"
|
|
You also need to load a VGA ROM BIOS into
|
|
C0000.
|
|
|
|
Examples:
|
|
vgaromimage: bios/VGABIOS-elpin-2.40
|
|
vgaromimage: bios/VGABIOS-lgpl-latest
|
|
vgaromimage: $BXSHARE/VGABIOS-lgpl-latest
|
|
|
|
.TP
|
|
.I "floppya: \fPor \fIfloppyb:"
|
|
|
|
Point this to the pathname of a floppy image
|
|
file or device. Floppya is the first drive,
|
|
and floppyb is the second drive. If you're
|
|
booting from a floppy, floppya should point to
|
|
a bootable disk.
|
|
|
|
You can set the initial status of the media to
|
|
'ejected' or 'inserted'. Usually you will want
|
|
to use 'inserted'.
|
|
|
|
Example:
|
|
|
|
2.88M 3.5" Floppy:
|
|
floppya: 2_88=path, status=ejected
|
|
|
|
1.44M 3.5" Floppy:
|
|
floppya: 1_44=path, status=inserted
|
|
|
|
1.2M 5.25" Floppy:
|
|
floppyb: 1_2=path, status=ejected
|
|
|
|
720K 3.5" Floppy:
|
|
floppya: 720k=path, status=inserted
|
|
|
|
360K 5.25" Floppy:
|
|
floppya: 360k=path, status=inserted
|

|
|
.TP
|
|
.I "ata0: \fP, \fIata1: \fP, \fIata2: \fPor \fIata3:"
|
|
|
|
These options enables up to 4 ata channels. For each channel
|
|
the two base io addresses and the irq must be specified.
|
|
ata0 is enabled by default, with ioaddr1=0x1f0, ioaddr2=0x3f0, irq=14
|
|
|
|
Examples:
|
|
ata0: enabled=1, ioaddr1=0x1f0, ioaddr2=0x3f0, irq=14
|
|
ata1: enabled=1, ioaddr1=0x170, ioaddr2=0x370, irq=15
|
|
ata2: enabled=1, ioaddr1=0x1e8, ioaddr2=0x3e0, irq=11
|
|
ata3: enabled=1, ioaddr1=0x168, ioaddr2=0x360, irq=9
|
|
|
|
.TP
|
|
.I "ata\fR[\fB0-3\fR]\fI-master: \fPor \fIata\fR[\fB0-3\fR]\fI-slave:"
|
|
|
|
This defines the type and characteristics of all attached ata devices:
|
|
type= type of attached device [disk|cdrom]
|
|
path= path of the image
|
|
mode= image mode [flat|concat|external|dll|sparse|vmware3|undoable|growing|volatile], only valid for disks
|
|
cylinders= only valid for disks
|
|
heads= only valid for disks
|
|
spt= only valid for disks
|
|
status= only valid for cdroms [inserted|ejected]
|
|
biosdetect= type of biosdetection [none|auto], only for disks on ata0 [cmos]
|
|
translation=type of transation of the bios, only for disks [none|lba|large|rechs|auto]
|
|
model= string returned by identify device command
|
|
journal= optional filename of the redolog for undoable and volatile disks
|
|
|
|
Point this at a hard disk image file, cdrom iso file,
|
|
or a physical cdrom device.
|
|
To create a hard disk image, try running bximage.
|
|
It will help you choose the size and then suggest a line that
|
|
works with it.
|
|
|
|
In UNIX it is possible to use a raw device as a Bochs hard disk,
|
|
but WE DON'T RECOMMEND IT.
|
|
|
|
The path, cylinders, heads, and spt are mandatory for type=disk
|
|
The path is mandatory for type=cdrom
|
|
|
|
The mode option defines how the disk image is handled. Disks can be defined as:
|
|
- flat : one file flat layout
|
|
- concat : multiple files layout
|
|
- external : developer's specific, through a C++ class
|
|
- dll : developer's specific, through a DLL
|
|
- sparse : stackable, commitable, rollbackable
|
|
- vmware3 : vmware3 disk support
|
|
- undoable : flat file with commitable redolog
|
|
- growing : growing file
|
|
- volatile : flat file with volatile redolog
|
|
|
|
The disk translation scheme (implemented in legacy int13 bios functions, and used by
|
|
older operating systems like MS-DOS), can be defined as:
|
|
- none : no translation, for disks up to 528MB (1032192 sectors)
|
|
- large : a standard bitshift algorithm, for disks up to 4.2GB (8257536 sectors)
|
|
- rechs : a revised bitshift algorithm, using a 15 heads fake physical geometry, for disks up to 7.9GB (15482880 sectors). (don't use this unless you understand what you're doing)
|
|
- lba : a standard lba-assisted algorithm, for disks up to 8.4GB (16450560 sectors)
|
|
- auto : autoselection of best translation scheme. (it should be changed if system does not boot)
|
|
|
|
Default values are:
|
|
mode=flat, biosdetect=auto, translation=auto, model="Generic 1234"
|
|
|
|
The biosdetect option has currently no effect on the bios
|
|
|
|
Examples:
|
|
ata0-master: type=disk, path=10M.sample, cylinders=306, heads=4, spt=17
|
|
ata0-slave: type=disk, path=20M.sample, cylinders=615, heads=4, spt=17

.TP
|
|
.I "com1:"
|
|
This defines a serial (COM) port. You can specify a device to use as com1.
|
|
This can be a real serial line, or a pty. To use a pty (under X/Unix),
|
|
create two windows (xterms, usually). One of them will run bochs, and the
|
|
other will act as com1. Find out the tty the com1 window using the `tty'
|
|
command, and use that as the `dev' parameter. Then do `sleep 1000000' in
|
|
the com1 window to keep the shell from messing with things, and run bochs in
|
|
the other window. Serial I/O to com1 (port 0x3f8) will all go to the other
|
|
window.
|
|
|
|
Examples:
|
|
com1: enabled=1, dev=/dev/ttyp7
|
|
com1: enabled=0
|
|
|
|
.TP
|
|
.I "parport1:"
|
|
This defines a parallel (printer) port. When turned on and an output file is
|
|
defined the emulated printer port sends characters printed by the guest
|
|
OS into the output file. On some platforms a device filename can be used to
|
|
send the data to the real parallel port (e.g. "/dev/lp0" on Linux).
|
|
|
|
Examples:
|
|
parport1: enabled=1, file=parport.out
|
|
parport1: enabled=1, file="/dev/lp0"
|
|
parport1: enabled=0
|
|
|
|
.TP
|
|
.I "newharddrivesupport:"
|
|
This setting enables support for large hard
|
|
disks, better CD recognition, and various
|
|
other useful functions. You can set it to
|
|
"enabled=1" (on) or "enabled=0" (off). It is
|
|
recommended that this setting is left on
|
|
unless you are having trouble with it.
|
|
|
|
Example:
|
|
newharddrivesupport: enabled=1
|
|
|
|
.TP
|
|
.I "boot:"
|
|
This defines your boot drive. You can either
|
|
boot from 'floppy', 'disk' or 'cdrom'.
|
|
(legacy 'a' and 'c' are also supported)
|
|
|
|
Example:
|
|
boot: disk
|
|
|
|
.TP
|
|
.I "floppy_bootsig_check:"
|
|
This disables the 0xaa55 signature check on boot floppies
|
|
The check is enabled by default.
|
|
|
|
Example:
|
|
floppy_bootsig_check: disabled=1
|
|
|
|
.TP
|
|
.I "log:"
|
|
Give the path of the log file you'd like Bochs
|
|
debug and misc. verbage to be written to. If
|
|
you really don't want it, make it /dev/null.
|
|
|
|
Example:
|
|
log: bochs.out
|
|
log: /dev/tty (unix only)
|
|
log: /dev/null (unix only)
|
|
|
|
.TP
|
|
.I "logprefix:"
|
|
This handles the format of the string prepended to each log line :
|
|
You may use those special tokens :
|
|
%t : 11 decimal digits timer tick
|
|
%i : 8 hexadecimal digits of cpu0 current eip
|
|
%e : 1 character event type ('i'nfo, 'd'ebug, 'p'anic, 'e'rror)
|
|
%d : 5 characters string of the device, between brackets
|
|
|
|
Default : %t%e%d
|
|
|
|
Examples:
|
|
logprefix: %t-%e-@%i-%d
|
|
logprefix: %i%e%d
|
|
|
|
.TP
|
|
.I "panic:"
|
|
If Bochs reaches a condition where it cannot
|
|
emulate correctly, it does a panic. This can
|
|
be a configuration problem (like a misspelled
|
|
bochsrc line) or an emulation problem (like an
|
|
unsupported video mode). The "panic" setting
|
|
in bochsrc tells Bochs how to respond to a
|
|
panic. You can set this to fatal (terminate
|
|
the session), report (print information to
|
|
the console), or ignore (do nothing).
|
|
|
|
The safest setting is action=fatal. If you are
|
|
getting panics, you can try action=report
|
|
instead. If you allow Bochs to continue after
|
|
a panic, don't be surprised if you get strange
|
|
behavior or crashes if a panic occurs. Please
|
|
report panic messages unless it is just a
|
|
configuration problem like "could not find
|
|
hard drive image."
|
|
|
|
Example:
|
|
panic: action=fatal
|
|
|
|
|
|
.TP
|
|
.I "error:"
|
|
Bochs produces an error message when it finds
|
|
a condition that really shouldn't happen, but
|
|
doesn't endanger the simulation. An example of
|
|
an error might be if the emulated software
|
|
produces an illegal disk command.
|
|
|
|
The "error" setting tells Bochs how to respond
|
|
to an error condition. You can set this to
|
|
fatal (terminate the session), report (print
|
|
information to the console), or ignore (do
|
|
nothing).
|
|
|
|
Example:
|
|
error: action=report
|
|
|
|
.TP
|
|
.I "info:"
|
|
This setting tells Bochs what to do when an
|
|
event occurs that generates informational
|
|
messages. You can set this to fatal (that
|
|
would not be very smart though), report (print
|
|
information to the console), or ignore (do
|
|
nothing). For general usage, the "report"
|
|
option is probably a good choice.
|
|
|
|
Example:
|
|
info: action=report
|
|
|
|
.TP
|
|
.I "debug:"
|
|
This setting tells Bochs what to do with
|
|
messages intended to assist in debugging. You
|
|
can set this to fatal (but you shouldn't),
|
|
report (print information to the console), or
|
|
ignore (do nothing). You should generally set
|
|
this to ignore, unless you are trying to
|
|
diagnose a particular problem.
|
|
|
|
.B NOTE:
|
|
When action=report, Bochs may spit out
|
|
thousands of debug messages per second, which
|
|
can impact performance and fill up your disk.
|
|
|
|
Example:
|
|
debug: action=ignore
|
|
|
|
.TP
|
|
.I "debugger_log:"
|
|
Give the path of the log file you'd like Bochs to log debugger output.
|
|
If you really don't want it, make it '/dev/null', or '-'.
|
|
|
|
Example:
|
|
log: debugger.out
|
|
log: /dev/null (unix only)
|
|
log: -

.I "sb16:"
|
|
This defines the SB16 sound emulation. It can
|
|
have several of the following properties. All
|
|
properties are in this format:
|
|
sb16: property=value
|
|
|
|
|
|
.B PROPERTIES FOR sb16:
|
|
|
|
midi:
|
|
|
|
The filename is where the midi data is sent.
|
|
This can be a device or just a file if you
|
|
want to record the midi data.
|
|
|
|
midimode:
|
|
|
|
0 = No data should be output.
|
|
1 = output to device (system dependent - midi
|
|
denotes the device driver).
|
|
2 = SMF file output, including headers.
|
|
3 = Output the midi data stream to the file
|
|
(no midi headers and no delta times, just
|
|
command and data bytes).
|
|
|
|
wave:
|
|
|
|
This is the device/file where wave output is
|
|
stored.
|
|
|
|
wavemode:
|
|
|
|
0 = no data
|
|
1 = output to device (system dependent - wave
|
|
denotes the device driver).
|
|
2 = VOC file output, including headers.
|
|
3 = Output the raw wave stream to the file.
|
|
|
|
log:
|
|
|
|
The file to write the sb16 emulator messages to.
|
|
|
|
loglevel:
|
|
|
|
0 = No log.
|
|
1 = Only midi program and bank changes.
|
|
2 = Severe errors.
|
|
3 = All errors.
|
|
4 = All errors plus all port accesses.
|
|
5 = All errors and port accesses plus a lot
|
|
of extra information.
|
|
|
|
dmatimer:
|
|
|
|
Microseconds per second for a DMA cycle. Make
|
|
it smaller to fix non-continous sound. 750000
|
|
is usually a good value. This needs a
|
|
reasonably correct setting for IPS (see
|
|
below).
|
|
|
|
|
|
Example:
|
|
sb16: midimode=1, midi=/dev/midi00,
|
|
wavemode=1, wave=/dev/dsp, loglevel=2,
|
|
log=sb16.log, dmatimer=600000
|

.B NOTE:
|
|
The example is wrapped onto three lines for

|
formatting reasons, but it should all be on
|
|
one line in the actual bochsrc file.

|
.TP
|
|
.I "vga_update_interval:"
|
|
Video memory is scanned for updates and screen
|
|
updated every so many virtual seconds. The
|
|
default is 300000, about 3Hz. This is
|
|
generally plenty. Keep in mind that you must
|
|
tweak the 'ips:' directive to be as close to
|
|
the number of emulated instructions-per-second
|
|
your workstation can do, for this to be
|
|
accurate.
|

|
|
.I "keyboard_serial_delay:"
|
|
Approximate time in microseconds that it takes

|
keyboard to controller over the serial path.
|
|
|

Example:
|
|
keyboard_serial_delay: 200
|
|
|
|
.TP
|
|
.I "keyboard_paste_delay:"
|
|
Approximate time in microseconds between attempts to paste
|
|
characters to the keyboard controller. This leaves time for the
|
|
guest os to deal with the flow of characters. The ideal setting
|
|
depends on how your operating system processes characters. The
|
|
default of 100000 usec (.1 seconds) was chosen because it works
|
|
consistently in Windows.
|
|
|
|
If your OS is losing characters during a paste, increase the paste
|
|
delay until it stops losing characters.
|
|
|
|
Example:
|
|
keyboard_paste_delay: 100000
|
|
|
|
.TP
|
|
.I "floppy_command_delay:"
|
|
Time in microseconds to wait before completing
|
|
some floppy commands such as read, write,
|
|
seek, etc., which normally have a delay
|
|
associated. This was previous hardwired to
|
|
50,000.
|
|
|
|
Example:
|
|
floppy_command_delay: 50000
|
|
|
|
.TP
|
|
.I "ips:"
|
|
Emulated Instructions Per Second. This is the
|
|
number of IPS that bochs is capable of running
|
|
on your machine. You can recompile Bochs,
|
|
using instructions included in config.h (in
|
|
the source code), to find your workstation's
|
|
capability.
|
|
|
|
IPS is used to calibrate many time-dependent
|
|
events within the bochs simulation. For
|
|
example, changing IPS affects the frequency of
|
|
VGA updates, the duration of time before a key
|
|
starts to autorepeat, and the measurement of
|
|
BogoMips and other benchmarks.
|
|
|

|
|
This defines the parameters of the clock inside Bochs.
|
|
|
|
sync
|
|
|
|
TO BE COMPLETED (see Greg explaination in bug #536329)
|
|
|
|
time0
|
|
|
|
Specifies the start (boot) time of the virtual machine. Use a time
|
|
value as returned by the time(2) system call. If no time0 value is
|
|
set or if time0 equal to 1 (special case) or if time0 equal 'local',
|
|
the simulation will be started at the current local host time.
|
|
If time0 equal to 2 (special case) or if time0 equal 'utc',
|
|
the simulation will be started at the current utc time.
|
|
|
|
Syntax:
|
|
clock: sync=[none|slowdown|realtime], time0=[timeValue|local|utc]
|
|
|
|
Default value are sync=none, time0=local
|
|
|
|
Example:
|
|
clock: sync=realtime, time0=938581955 # Wed Sep 29 07:12:35 1999
|
|
|
|
.TP
|
|
.I "mouse:"
|
|
This option prevents Bochs from creating mouse
|
|
"events" unless a mouse is enabled. The
|
|
hardware emulation itself is not disabled by
|
|
this. You can turn the mouse on by setting
|
|
enabled to 1, or turn it off by setting
|
|
enabled to 0. Unless you have a particular
|
|
reason for enabling the mouse by default,
|
|
it is recommended that you leave it off.
|
|
|
|
Example:
|
|
mouse: enabled=1
|
|
mouse: enabled=0
|
|
|
|
.TP
|
|
.I "private_colormap:"
|
|
Requests that the GUI create and use it's own
|
|
non-shared colormap. This colormap will be
|
|
used when in the bochs window. If not enabled,
|
|
a shared colormap scheme may be used. Once
|
|
again, enabled=1 turns on this feature and 0
|
|
turns it off.
|
|
|
|
Example:
|
|
private_colormap: enabled=1
|
|
|
|
.TP
|
|
.I "i440fxsupport:"
|
|
Enables limited i440fx PCI chipset support.
|
|
|
|
Example:
|
|
i440fxsupport: enabled=1
|
|
|
|
.TP
|
|
.I "ne2k:"
|
|
Defines the characteristics of an attached ne2000 isa card :
|
|
ioaddr=IOADDR,
|
|
irq=IRQ,
|
|
mac=MACADDR,
|
|
ethmod=MODULE,
|
|
ethdev=DEVICE,
|
|
script=SCRIPT
|
|
|
|
.B PROPERTIES FOR ne2k:
|
|
|
|
ioaddr, irq:
|
|
You probably won't need to change ioaddr and irq, unless there are IRQ conflicts.
|
|
|
|
mac:
|
|
The MAC address MUST NOT match the address of any machine on the net.
|
|
Also, the first byte must be an even number (bit 0 set means a multicast
|
|
address), and you cannot use ff:ff:ff:ff:ff:ff because that's the broadcast
|
|
address. For the ethertap module, you must use fe:fd:00:00:00:01. There may
|
|
be other restrictions too. To be safe, just use the b0:c4... address.
|
|
|
|
ethmod:
|
|
The ethmod value defines which low level OS specific module to be used
|
|
to access pysical ethernet interface. Current implemented values include
|
|
- fbsd : ethernet on freebsd and openbsd
|
|
- linux : ethernet on linux
|
|
- win32 : ethernet on win32
|
|
- tap : ethernet through a linux tap interface
|
|
- tuntap : ethernet through a linux tuntap interface
|
|
|
|
ethdev:
|
|
The ethdev value is the name of the network interface on your host
|
|
platform. On UNIX machines, you can get the name by running ifconfig. On
|
|
Windows machines, you must run niclist to get the name of the ethdev.
|
|
Niclist source code is in misc/niclist.c and it is included in Windows
|
|
binary releases.
|
|
|
|
script:
|
|
The script value is optionnal, and is the name of a script that
|
|
is executed after bochs initialize the network interface. You can use
|
|
this script to configure this network interface, or enable masquerading.
|
|
This is mainly useful for the tun/tap devices that only exist during
|
|
Bochs execution. The network interface name is supplied to the script
|
|
as first parameter
|
|
|
|
Examples:
|
|
ne2k: ioaddr=0x240, irq=9, mac=b0:c4:20:00:00:00, ethmod=fbsd, ethdev=xlo
|
|
ne2k: ioaddr=0x240, irq=9, mac=b0:c4:20:00:00:00, ethmod=linux, ethdev=eth0
|
|
ne2k: ioaddr=0x240, irq=9, mac=b0:c4:20:00:00:01, ethmod=win32, ethdev=MYCARD
|
|
ne2k: ioaddr=0x240, irq=9, mac=fe:fd:00:00:00:01, ethmod=tap, ethdev=tap0
|
|
ne2k: ioaddr=0x240, irq=9, mac=fe:fd:00:00:00:01, ethmod=tuntap, ethdev=tun0, script=./tunconfig
|
|
|
|
.TP
|
|
.I "keyboard_mapping:"
|
|
This enables a remap of a physical localized keyboard to a
|
|
virtualized us keyboard, as the PC architecture expects.
|
|
If enabled, the keymap file must be specified.
|
|
|
|
Examples:
|
|
keyboard_mapping: enabled=1, map=gui/keymaps/x11-pc-de.map
|
|
|
|
.TP
|
|
.I "keyboard_type:"
|
|
Type of emulated keyboard sent back to the OS
|
|
to a "keyboard identify" command. It must be
|
|
one of "xt", "at" or "mf".
|
|
|
|
Example:
|
|
keyboard_type: mf
|
|
|
|
.TP
|
|
.I "user_shortcut:"
|
|
This defines the keyboard shortcut to be sent when you press the "user"
|
|
button in the headerbar. The shortcut string can be a combination of
|
|
these key names: "alt", "bksp", "ctrl", "del", "esc", "f1", "f4", "tab",
|
|
"win". Up to 3 keys can be pressed at a time.
|
|
|
|
Example:
|
|
user_shortcut: keys=ctrlaltdel
|
|
|
|
.TP
|
|
.I "cmosimage:"
|
|
This defines image file that can be loaded into the CMOS RAM at startup.
|
|
|
|
Example:
|
|
cmosimage: cmos.img
|
|
|
|
.TP
|
|
.I "usb1:"
|
|
Enables the i440fx PCI USB root hub. USB devices with access to real hardware
|
|
are not implemented yet. PCI support must be enabled, too.
|
|
|
|
Example:
|
|
usb1: enabled=1, ioaddr=0xFF80, irq=10
|
|
|
|
.TP
|
|
.I "diskc:"
|
|
or
|
|
.I "diskd:"
|
|
|
|
The \fBdiskc\fR and \fBdiskd\fR options are deprecated. Use \fBata*\fR
|
|
options instead.
|
|
|
|
Point this at the disk image you want to use
|
|
as for a hard disk. If you use bximage(1) to
|
|
create the image, it will give you the
|
|
required cyl, head, and spt information.
|
|
diskc is the first hard drive, and diskd is the
|
|
second hard drive.
|
|
|
|
.B NOTE:
|
|
You cannot use both diskd and cdromd together.
|
|
|
|
Example:
|
|
diskc: file=10M.i, cyl=306, heads=4, spt=17
|
|
diskc: file=112M.i, cyl=900, heads=15, spt=17
|
|
diskd: file=483.i, cyl=1024, heads=15, spt=63
|
|
|
|
.TP
|
|
.I "cdromd:"
|
|
|
|
The \fBcdromd\fR option is deprecated. Use \fBata*\fR options instead.
|
|
|
|
Point this to a pathname of a raw CD-ROM device.
|
|
There is no cdromc option, only cdromd.
|
|
|
|
.B NOTE:
|
|
You cannot use both diskd and cdromd together.
|
|
|
|
|
|
Example:
|
|
cdromd: dev=/dev/cdrom, status=inserted
|
|
cdromd: dev=/dev/cdrom, status=ejected
|
|
|
|
.TP
|
|
.I "pit:"
|
|
The \fBpit\fR option is deprecated. Use the \fBclock\fR option instead.
|
|
|
|
The PIT is the programmable interval timer. It has an option that tries to
|
|
keep the PIT in sync with real time. This feature is still experimental,
|
|
but it may be useful if you want to prevent Bochs from running too fast, for
|
|
example a DOS video game. Be aware that with the realtime pit option, your
|
|
simulation will not be repeatable; this can a problem if you are debugging.
|
|
|
|
Example:
|
|
pit: realtime=1
|
|
|
|
.TP
|
|
.I "time0:"
|
|
The \fBtime0\fR option is deprecated. Use the \fBclock\fR option instead.
|
|
|
|
Specifies the start (boot) time of the virtual machine. Use a
|
|
time value as returned by the time(2) system call. Time
|
|
equal to 1 is a special case which starts the virtual machine at the
|
|
current time of the simulator host.
|
|
|
|
Example:
|
|
time0: 938581955
