Changes in 1.2.1 (June 12, 2001):
|
|
- more work on makefile for building RPMs
|
|
- [ #432382 ] build debian packages patch
|
|
add build/debian directory from Rob Lemley <rjlemley@calypsoblue.org>
|
|
which allows us to make Debian packages!
|
|
- optimize for speed when simulating one processor. Now 1-processor
|
|
performance should be equivalent to 1.1.2.
|
|
- [ #425640 ] sb16 assumes fpos_t is long int
|
|
This fixes compiles of iodev/sb16.cc on linux systems with newer libraries
|
|
in which fpos_t is not an integer.
|
|
- [ #432488 ] SMP:assert "n_logfn < MAX_LOGFNS" fails
|
|
increase MAX_LOGFNS since we ran out of them on an SMP simulation with
|
|
4 processors
|
|
- changes to compile clean on cygwin:
|
|
- don't use the WIN32 snprintf define for cygwin
|
|
- add ssize_t definition for cygwin
|
|
- only compile "struct timeval tval" if select is available
|
|
on that platform.
|
|
- [ #432491 ] SMP: CPUID says no APIC feature
|
|
clean up inconsistent use of BX_SUPPORT_APIC and BX_APIC_SUPPORT, which
|
|
caused the CPUID to report no APIC was present
|
|
- [ #431025 ] --enable-external-device-models broken
|
|
removed configure options for external-device-models and
|
|
external-cpu-memory. These don't work and aren't going to be fixed.
|
|
- [ #429448 ] configure: -lreadline when not there
|
|
Now configure allows you to choose not to use readline, even if it's found
|
|
on your system.
|
|
- [ #428915 ] apply extended keyboard patch
|
|
extended keyboard patch by Dave Poirier <eks@void-core.2y.net>
|
|
- [ #428626 ] if no X11 found, configure&make fails
|
|
Now configure halts if X windows is selected but no X libraries are found.
|
|
- updated rombios to version 1.13. This fixes several problems:
|
|
- [ #430472 ] DOS HIMEM "A20 line" error
|
|
This problem was apparantly caused when Bryce added a function that prints
|
|
the BIOS version, and he called it too early in the boot process. Now the
|
|
same function is called later, and it doesn't break the A20.
|
|
- [ #431010 ] SMP structure overwritten in v1.2
|
|
SMP structures were getting overwritten by BCC-generated data,
|
|
preventing SMP operating systems from detecting that other processors
|
|
were available.
|
|
- [ #431016 ] bios: SMP struct has wrong entry count
|
|
SMP structure had the wrong entry counts
|
|
- very minor doc updates (typos, replace broken link to mtools info)
|
|
- quit when the user clicks the power button, even if they have disabled
|
|
panics.
|
|
- win32 now defaults to having mouse capture mode turned off. For new users,
|
|
it would be distressing for their mouse cursor to disappear until they
|
|
pressed F12.
|
|
- [ #428222 ] vga font not installed
|
|
added script called "install-x11-fonts" which should help people install
|
|
the VGA font on X windows systems, if it isn't already there.
|
|
|
|
Changes in 1.2 (June 3, 2001):
|
|
- [ #427259 ] rombios HALT calls don't print
|
|
Fixed bios/rombios.c HALT macro so that it writes the line number of the
|
|
panic to the PANIC_PORT (port 0x400) and then does NOT do a halt
|
|
instruction. Also changed iodev/unmapped.cc so that the line number written
|
|
to PANIC_PORT is displayed as a BX_PANIC message. Because the HALT
|
|
macro now triggers the normal panic behavior, it can be controlled by
|
|
the bochsrc.
|
|
- [ #429016 ] crash if no hard drive
|
|
rombios used to call HALT macro if no hard drive was found. Now it only
|
|
calls HALT if a hard drive has an illegal geometry.
|
|
- [ #425388 ] include source for simple disk img tool
|
|
[ #428478 ] mkimg tool creates image 1 byte too big
|
|
Added bximage tool, which makes empty floppy and hard disk images.
|
|
It is now included in the top level Makefile, so it will get built
|
|
by default on all platforms.
|
|
- [ #426036 ] eth_fbsd.cc compile problem on solaris26
|
|
added configure test so that "configure --enable-ne2000" only
|
|
includes the Berkeley Packet Filter code (eth_fbsd) if the header
|
|
file <net/bpf.h> can be found. If you don't have BPF the ne2000
|
|
will not actually move packets, but at least it will compile clean now.
|
|
- [ #428214 ] 1.2.pre1 need documentation for binaries
|
|
Write windows and linux specific documentation to be installed in
|
|
binary releases.
|
|
- [ #429258 ] disable RESET for version 1.2
|
|
Since soft reset was not completely working, I reverted the reset patch.
|
|
Now it does panics on reset instead of trying to reboot, as the old
|
|
bochs versions did.
|
|
- [ #428222 ] Should the linux RPM install vga font?
|
|
now font/vga.pcf will be installed in the RPM package
|
|
- [ #429020 ] stop renaming the BIOS!!!
|
|
new BIOS changes are now in BIOS-bochs-latest, instead of a BIOS
|
|
whose name changes every time we change anything! To help distinguish
|
|
different BIOS versions, the BIOS now prints its RCS Id into the
|
|
log file.
|
|
- [ #428625 ] compile problem if SHOW_IPS is on
|
|
removed extra paren that broke SHOW_IPS
|
|
- [ #428219 ] PCI doesn't compile with SMF=1
|
|
- [ #429375 ] pthreads detection broken
|
|
- [ #429073 ] configure: if no X11, makes bad config
|
|
- [ #429229 ] install current .bochsrc in binary rels
|
|
- install Tim's man pages on linux RPM
|
|
- BIOS prints messages in log in case of boot failure
|
|
- rewrote instructions for compiling in win32 (win32.txt)
|
|
- fixed link in HTML changelog.html to point to the real sources on SF.
|
|
- added missing LOG_THIS definition to gui/nogui.cc and gui/rfb.cc
|
|
- added additional check for null pointer in debugger exit routine
|
|
- added diskd to .bochsrc
|
|
|
|
Changes in version 1.2-pre1 (May 25, 2001):
|
|
- major cleanup of .bochsrc
|
|
- major cleanup of stderr output: prints bochs version information when
|
|
starting, and at the end it tries to print the message that caused
|
|
bochs to quit.
|
|
- two hard disk support (diskd). At present, you cannot have two
|
|
hard drives and a cdrom at the same time, because there is only
|
|
one IDE controller with two channels.
|
|
- split hard disk support allows different partitions to be stored in
|
|
different image files
|
|
- two new GUI choices: term mode and RFB mode. Term is a text-only
|
|
interface, and RFB creates a server that can be accessed using
|
|
the AT&T VNC viewer.
|
|
- now Bochs can simulate an SMP machine, if you configure with
|
|
--enable-processors=N. Configuring more than one processor has
|
|
a major performance impact, so the default is 1 processor.
|
|
See SMP documentation for more details.
|
|
- to make SMP work, bx_mem and bx_cpu have been replaced with
|
|
bx_mem_array[] and bx_cpu_array[]. The cpus are referenced through
|
|
the BX_CPU(n) macro and memories through the BX_MEM(n). Normal
|
|
mode has one cpu and one memory, SMP mode has multiple cpu's and
|
|
one memory, cosimulation mode has multiple cpus and multiple memories.
|
|
- use --enable-cpu-level=6 to make Bochs claim to be a Pentium Pro.
|
|
The only feature that requires CPU level 6 is apic support.
|
|
- new logging system by Todd Fries, which has 4 levels of event
|
|
severity (panic, error, info, debug). There are new .bochsrc
|
|
options that control what action to take when a
|
|
panic/error/info/debug event occurs.
|
|
- now searches for .bochsrc, bochsrc, bochsrc.txt, and (on unix only)
|
|
$HOME/.bochsrc.
|
|
- use GNU readline library if --enable-debugger is on, as long as readline
|
|
can be found on the machine
|
|
- configure checks for existence strtoull and strtouq. if neither exists,
|
|
Bochs uses its own implementation
|
|
- applied patches from Cliff Hones <cliff@aonix.co.uk> to fix up the
|
|
rombios. This includes many improvements, which you can list by
|
|
doing "cvs log -r 1.6 bios/rombios.c" or looking at cvsweb.
|
|
- added suggested geometries of larger disks to the documentation
|
|
- this is the first release to have official binary packages for win32
|
|
and Linux. There is a new "make rpm" in the top-level Makefile which
|
|
will create an RPM of the current bochs directory. To use this,
|
|
become root and type "configure; make rpm".
|
|
- applied some FreeBSD patches from Maxim Sobolev (cdrom and serial).
|
|
|
|
Changes in version 1.1.2 (bugfix3, May 16, 2001):
|
|
- updated Elpin VGA BIOS to version 2.40, and changed pointer in .bochsrc
|
|
- fixed .conf.x86 script so that it uses c++ instead of egcs for C++ files
|
|
- now Makefile targets that recurse into subdirectories use double colons,
|
|
so that it will always recurse into subdirectories. Now a single make
|
|
command should notice a modified source file in a subdir.
|
|
- fixed bug in bx_panic. If BX_PANIC_IS_FATAL==0 and a (non-fatal) panic
|
|
occurs, it used to call bx_atexit() and then return. It should never
|
|
call bx_atexit, which starts to shut down the simulator, unless it's
|
|
really going to quit!
|
|
- support 2.88 MB floppy disks
|
|
- since dataseghack is checked in as non-executable, invoke it with
|
|
"csh dataseghack"
|
|
- double fault patch from Thomas Petazzoni <thomas.petazzoni@ifrance.com>,
|
|
sourceforge patch #423726.
|
|
- removed -fno-builtin from fpu makefiles
|
|
- redefine u_char, u_short, etc. in order to not conflict with system
|
|
definitions of these same types.
|
|
- in cdrom.cc, remove the extern "C" { } structure around some of the
|
|
header files. This is no longer necessary.
|
|
- do not panic on hard disk command 0x1f2 (read sector count)
|
|
- in keyboard.cc:
|
|
- apply Todd Fries' reset patch
|
|
- recognize most of the "Grey" insert/delete/home/end/etc. keys the
|
|
same as keypad keys.
|
|
- removed panic on "kbd_ctrl_to_kbd(): got value of 0x??"
|
|
- implement mouse command 0xf6 (set defaults)
|
|
- apply Suboner@aol.com's Xwindows timing patch from
|
|
http://sourceforge.net/tracker/index.php?func=detail&aid=418730&group_id=12580&atid=312580
|
|
- remove all patches from patches subdir which have already been applied.
|
|
The remaining ones are under consideration but not applied.
|
|
|
|
Changes in version 1.1.1 (bugfix2, April 9, 2001):
|
|
- in soundwin.cc, arg 3 should be typecast to LPWAVEFORMATEX
|
|
- in fpu_entry.c, Bryce mistyped his own initials!
|
|
- in configure.in and configure, define good defaults for VC++

|
(FIXED, patch #413574: portable1)
|

then later cast to a pointer and dereferenced, which crashes any 64-bit
|
|
machine.
|
|
|
|
(FIXED, patch #413574: portable1)
|
|
some machines have no snprintf or strtoull. include a replacement function
|
|
when needed.

Some compilers don't allow "typedef struct { } foo;"
|
|
|
|
(FIXED, patch #413574: portable1)
|

|
|
in fpu_entry.c, FPU_load_int32 was consistently called with arg1 of

|
|
(FIXED, patch #413574: portable1)
|
|

|
WinME install dies with panic:
|
|
bochs: panic, pit: outp(43h): comm Bh, mode 00, bcd 00 unhandled
|
|
I think I had a similar problem. All three timers should support modes
|
|
0, 2, and 3. Other modes really aren't implemented.
|
|
|
