Source code for Bochs, is available from the Bochs home page
|
|
|
|
|
at <a href="http://bochs.sourceforge.net">bochs.sourceforge.net</a>.
|
|
|
|
|
You can download the most recent release, or use CVS to check
|
|
|
|
|
out the latest sources. The releases are the most likely to compile
|
|
|
|
|
and run without modification, but if you want the very newest features
|
|
|
|
|
try CVS instead.

All releases are gzip'd tar files. That means the whole Bochs source
|
|
|
|
|
code directory has been
|
|
|
|
|
consolidated into one file using the Unix command 'tar', then compressed
|
|
|
|
|
to save space with GNU 'gzip'.
|
|
|
|
|
To extract the source code, you'll need both 'tar' and 'gzip/gunzip'.
|
|
|
|
|
All files are contained within one
|
|
|
|
|
subdirectory named 'bochs-YYMMDDv'.
|
|
|
|
|
|
|
|
|
|
<PRE>
|
|
|
|
|
cd /path/parent-directory
|
|
|
|
|
gzip -dc bochs-YYMMDDv.tar.gz | tar -xvf -
|
|
|
|
|
cd bochs-YYMMDDv
|
|
|
|
|
</PRE>
|
|
|
|
|
|
|
|
|
|
Before compiling, you'll need to run the configure script, which will configure
|
|
|
|
|
source code to run
|
|
|
|
|
on your system, and with your chosen options. There are many
|
|
|
|
|
options to 'configure', and you probably don't need any of them.
|
2001-05-30 22:24:48 +04:00
|
|
|
For example, if you run BeOS, specify '--with-beos' to configure.
|

|
|
|
To see a complete list:
|
|
|
|
|
|
|
|
|
|
<PRE>
|
|
|
|
|
unix-> ./configure --help
|
|
|
|
|
</PRE>
|
|
|
|
|
|
|
|
|
|
For more complete documentation of options available to configure,
|
|
|
|
|
click on <a href="configure.html">this link</a>.
|
|
|
|
|
<p>
|
|
|
|
|
You will also need to set
|
|
|
|
|
environment variables to tell configure what compiler and options
|
|
|
|
|
to use. Check out <a href="configure.html">this link</a>.
|
|
|
|
|
It's the same as the one above.
|
|
|
|
|
<p>
|
|
|
|
|
|
|
|
|
|
Now run configure, be it manually or by way of a script file.
|
|
|
|
|
<PRE>
|
|
|
|
|
unix-> ./configure
|
|
|
|
|
-or-
|
|
|
|
|
unix-> ./.conf.x86
|
|
|
|
|
</PRE>
|
|
|
|
|
|
|
|
|
|
<P>If the configure script bombs, check 'config.log'. Specifically,
|
|
|
|
|
look for errors returned
|
|
|
|
|
by the compiler. You may have options incompatible with your
|
|
|
|
|
compiler. See the link on setting the environment variables above.
|
|
|
|
|
|
|
|
|
|
<P>
|
|
|
|
|
Assuming at this point all went well with the configure command,
|
|
|
|
|
edit the file 'config.h', which was generated by ./configure.
|
|
|
|
|
Look for the USER CONFIGURABLE OPTIONS section. Each parameter
|
|
|
|
|
available for editing is documented. Generally the
|
|
|
|
|
defaults are fine for typical users.
|
|
|
|
|
Please read about each
|
|
|
|
|
parameter and edit carefully. <B>NOTE:</B> This file is
|
|
|
|
|
generated, and will be deleted if you run 'make dist-clean'.
|
|
|
|
|
|
|
|
|
|
<P>
|
|
|
|
|
You may now compile the source.

In text mode, Bochs requires your X server to have access to the
|
|
|
|
|
VGA font. If you don't already have it, you must install it from
|
|
|
|
|
one of the font files in bochs-yymmdd/font.
|
|
|
|
|
<P>
|
|
|
|
|
There are two options; you may install the VGA font in a global place, or
|
|
|
|
|
in a local directory. You may need to install it locally if you don't have
|
|
|
|
|
root access.

# NOTE1: Make sure your DISPLAY variable points to local machine.

|
|
|
# Solaris 2.x /usr/openwin/lib/X11/fonts

|
|
# Linux /usr/lib/X11/fonts/

root-> compress font-path-here/misc/vga.pcf

<B>Hard Drive Image File: </B> Bochs emulates a hard drive by using a
|
|
|
|
|
large Unix file, which you must create. The size of the hard drive is
|
|
|
|
|
dependent upon the number of cylinders, heads, and sectors-per-track that
|
|
|
|
|
you would like to emulate. Here are some examples of possible

drive geometries:

For hard disk sizes larger than 528MB, be sure that newharddrivesupport is
|
|
|
|
|
enabled. This will be the compiled default in a future release, but for now
|
|
|
|
|
your .bochsrc still needs the line "newharddrivesupport: enabled=1" in order
|
|
|
|

to support >1024 cylinders.

Pick the size of the hard drive you want to emulate, and create a blank file
|
|
|
|
|
according to the parameters in the table. If you have the 'dd' command,
|
|
|
|
|
you can use it to create the file. Keeping in mind that there are 512 bytes
|
|
|
|
|
in a sector, just use the number of "Sectors Total" from the table as the
|
|
|
|
|
'count=' option to dd, and tell dd to use a block size ('bs=') the same as
|
|
|
|
|
a disk sector size (512). For example, for a 112MB drive, there are 229500
|
|
|
|
|
(900*15*17) sectors.

|
<B>Floppy Disk Image File:</B> Bochs emulates a floppy drive/disk using either
|
|
|
|
|
a Unix file, or a real floppy drive Unix device. To use either, you will need
|
|
|
|
|
an entry in your '.bochsrc' file pointing to the regular or device file. Use
|
|
|
|
|
the 'floppya:' and 'floppyb:' directives. If you are starting out, you will
|
|
|
|
|
need to make a copy of an <I>existing</I> bootable floppy. Otherwise, you may create
|
|
|
|
|
a <I>blank</I> image file, if you intend on formatting it using the OS you boot
|
|
|
|
|
within Bochs.

To create a <I>blank floppy image file</I>, you can use the same concept as above for
|
|
|
|
|
creating blank hard disk image files. For example, to create a blank 1.44MB
|
|
|
|
|
floppy image file:
|
|
|
|
|
<PRE>
|
|
|
|
|
unix-> dd if=/dev/zero of=1.44M bs=512 count=2880
|
|
|
|
|
</PRE>
|
|
|
|
|
|
|
|
|
|
To create a <I>copy of an existing floppy disk</I>, granted you have a floppy disk
|
|
|
|
|
drive on your workstation, you can use one of the following commands, where
|
|
|
|
|
'/dev/fd0' would be the path to your floppy drive device name.
|
|
|
|
|
<P><B>NOTE:</B> If your system uses a form of volume management to automount
|
|
|
|
|
your floppy drive, you may have to tell it you popped in a new floppy,
|
|
|
|
|
and use an alternative device name to access it.
|
|
|
|
|

There are many options which you can change, to alter the behaviour
|
|
|
|
|
of bochs, enable features, etc. You can set values for these options
|
|
|
|
|
in a file called <B>".bochsrc"</B>. There should be a reference
|
|
|
|
|
file with this name, that comes with the source code distribution.
|
|
|
|
|
As, it's easier to maintain documenting possible commands in
|
|
|
|
|
the file itself, look in the reference file for more info.

You may now pass all options available in the ".bochsrc" file, to
|
|
|
|
|
bochs on the command line. Syntax for command line options is
|
|
|
|
|
now identical to directives in ".bocshrc". Old command line options,
|
|
|
|
|
such as <B>-bootC</B> are no longer valid.
|
|
|
|
|
|
|
|
|
|
Bochs expects that each option is passed as a single argument, so if
|
|
|
|
|
you need to use spaces, surround the option in quotes. For example:
|
|
|
|
|
|
|
|
|
|
<PRE>
|
|
|
|
|
bochs boot:c
|
|
|
|
|
bochs "boot: c" "diskc: file=../10M.vga, cyl=306, heads=4, spt=17"
|
|
|
|
|
bochs romimage:/tmp/someimage
|
|

</PRE>
|

The goal of Bochs is to emulate the components of a basic PC (CPU, BIOS,
|
|
|
|
|
disk drive, floppy, keyboard, VGA, and other chipsets) well enough to allow
|
|
|
|
|
for multiple Operating Systems to run within the emulator. So far,
|
|
|
|
|
Bochs has been successful in running several OS's at
|
|
|
|
|
one time or the other. Follow the link of your choice to learn how
|
|
|
|
|
to install the OS of your interest.
