Changes in version 1.2-pre1 (5/25/2001): - 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 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, 5/16/2001): - 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 , 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, 4/9/2001): - 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++ #define BX_64BIT_CONSTANTS_USE_LL 0 #define inline __inline #define BX_NO_EMPTY_STRUCTS 1 #define BX_NO_ATTRIBUTES 1 #define BX_HAVE_HASH_MAP 0 - in config.h.in, fixed typo in #error message Changes in version 1.1 (bugfix1, 4/6/2001): (FIXED, patch #414360: update copyrights) update headers. Change copyright to 2001, replace config.h.in header with the standard mandrake header that every other file uses. (FIXED, patch #414356: inlines) make macro to replace inline and static/extern keywords. Then make define the macro appropriately based on configure. (FIXED: patch #414234: macos-no-strdup) --with-macos should force HAVE_STRDUP=0. (FIXED, patch #403027: Fix mouse bugs in Linux and BSD) Linux and BSD (maybe others) cause panic in mouse code. (FIXED, patch #413851: const64bit patch) VC++ does not allow "LL" after 64-bit constant. (FIXED, patch #413859: fabs symbol conflict) fpu code contains fabs, which conflicts with math library fabs. (FIXED, patch #403004: Implement aborts on a few SET FEATURE commands...) Implement aborts on a few SET FEATURE commands for ATA. (FIXED, patch #402991: Update to iodev/vga.cc to add 3c3h read support) Implement VGA enable register, at 0x3c3. (FIXED, patch #403027: Fix mouse bugs in Linux and BSD) Mouse panic in linux/BSD: KBD: io write 0x64: command = 0xD3(write mouse outb) (FIXED, patch #414229: panic-is-fatal) Allow user to decide if panic is fatal, or just a warning (FIXED, patch #414230: sun-cdrom) Support Sun CDROM (FIXED, patch #413574: portable1) there are cases where a pointer is cast to a 32-bit int, 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. (FIXED, patch #413574: portable1) Some compilers don't allow "typedef struct { } foo;" (FIXED, patch #413574: portable1) Some people don't have hash_map.h, used in dbg_main.cc. Disable this code if hash_map.h not found. (FIXED, patch #413574: portable1) Some compilers can't handle labels at the end of a block, as in void main () { /*code*/ label: } (FIXED, patch #413574: portable1) Most compilers can't handle __attribute__. Use macro to define it away. (FIXED, patch #413574: portable1) if --enable-debugger, turn on --enable-disasm too. (FIXED, patch #413574: portable1) ome compilers can't handle any chars after an #endif (FIXED, patch #413574: portable1) wrong type arg1 of bx_dbg_watch and bx_dbg_unwatch. The code in lexer.l was calling it with integers (not booleans) (FIXED, patch #413574: portable1) in fpu code, "setcc" macro was implemented with braces inside parens, which some compilers don't understand. (FIXED, patch #413574: portable1) in fpu_entry.c, FPU_load_int32 was consistently called with arg1 of type (s32 *), but should be (u32 *) (FIXED, patch #413574: portable1) comment out sigcontext structure in fpu/stubs/asm/sigcontext.h because it conflicted with sigcontext of other machines. This struct was never used by bochs anyway. (FIXED, patch #414046: portable2) move definition of missing library functions into osdep.h and osdep.cc, include contents of macutils*. (FIXED, patch #414061: win32-rawcd) CDROM drive letter for WIN32 should not be hardcoded. (FIXED, patch #414060: win32-rawfloppy) Bypass fstat when opening WIN32 raw floppy disk. (FIXED, patch #414226: pit-panic) 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.
