read/write commands)
- prepared i/o buffer for multi sector transfers
- power management commands "standby now" and "idle immediate" now returning success
- store size of virtual disk in sparse header to simplify geometry detection/check
- enabling geometry autodetection causes a panic if not supported by image
- simplified geometry detection code
- unsupported ATAPI commands now cause a BX_DEBUG message and no addtional
error code info (avoid flooding log file)
- a bunch of image size handling changes
* 'hd_size' contains the size of the virtual hard disk (for geometry check/detection)
* passing the size calculated from the geometry not needed in some cases
- indent mode changes
- siminterface get_param_*() methods num support a base parameter like the generic
get_param() method
- new parameter lists now also have a generated id
- test function print_tree() now handles enum parameters correctly
- proposed parameter tree updated
- clock/cmos menu added in textconfig and wx
- enum parameter type now supports new parameter handling
- long text format for numeric parameters added (useful when both textconfig and
wx are present)
- wx: handling of list flag USE_BOX_TITLE fixed
- textconfig: optional memory features moved to submenus
- siminterface generates a unique id for new parameters (used for wx dependencies)
- proposed parameter tree updated
- floppy options init code cleanup (still using old-style parameters)
* ports for error register, sector count and sector number are shared between
both drives
* status register always returns the values of the selected drive (0x00 if
not present
* set correct signature for both drives in case of reset
- read raw toc for image files and platforms other than Windows XP implemented (ported from qemu)
- several cdrom capacity fixes / report capacity only on Bochs init and cdrom change
- flag 'using_file' must be set to 0 for WIN32 ASPI or direct access
- multisession format handling removed from harddrv.cc (now handled in cdrom code)
- ATAPI error messages improved
- prepared ATAPI buffer for block size 2352
- read_block() now returns a bx_bool value and panic moved to hard drive code
- insert_cdrom() now uses read_block() to test the media presence
- small code cleanups
- sense code ASC_ILLEGAL_OPCODE added for unimplemented/unknown ATAPI commands
- some panics changed to errors
- unsupported bits message in drive and head register changed to BX_DEBUG
- improved info about not existing drive
- indent mode fixed in ATAPI packet command section
- cmos image options renamed
- new cmos option controls the usage of the RTC values from image

- MSVC warning fixed
- BM-DMA base address set to 0xc000 at reset (shoud be done by the PCI BIOS)
- BM-DMA status register write messages changed to BX_DEBUG
- fixed an MSVC warning in the harddrive code
images created with bximage (heads = 16, sectors per track = 63)
- size check for 'flat' hard disk images added. The image size is now compared
with the size calculated from the geometry.
* added prefix "ataX-Y:" to panic mesages (X=channel, Y=drive)
* added command_aborted() call after the panic
* fixed indent mode in the modified section
- report the cdrom capacity in megabytes instead of bytes
- don't flood the logfile with error messages when the guest OS checks the cdrom
unit periodicly for media presence
code. Up to 3 boot drives are supported now. TODO: new boot dialog for wx.
- config.cc: missing ask formats for enum parameters added
- wxdialog.cc: tab window now uses the label instead of the ask format if defined
bochs.h already not include iodev.h which reduces compilation dependences for almost all cpu and fpu files, now cpu files will not be recompiled if iodev includes was changed
* changed all %ll format descriptions to FMT_LL macro so that
Microsoft Visual C works correctly (it uses %I64)
* missing type conversions added
* cdrom.cc: variable types for win32 fixed
* removed some unused variables in eth_win32.cc and harddrv.cc
* added missing includes in make_cmos_image.c and niclist.c
You can now choose for each disk on the ata interfaces the
disk mode, between :
- 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
- growable : growing file
- volatile : flat file with volatile redolog
- z-undoable : gziped flat file with commitable redolog
- z-volatile : gziped flat file with volatile redolog
A new "bxcommit" utility can merge commitable redologs to
flat images.
- it works only on x86 with gcc2.95+
- uses the GCC function atribute "regparm(n)" to declare that certain
functions use the register calling convention
- performance improvement is about 6%
. read port 0x70 (cmos) : return index
. atapi function 46 and 4a : return error
- put back the log prefix for cmos that disappeared when we did the plugins
- if translation=auto :
. translation=none if cylinders <=1024 and heads <=16
. translation=large if cylinders * heads <= 131072
. transaltion=lba otherwise
- changes default translation value to "auto"
- add example in .bochsrc
"bx_bool" which is always defined as Bit32u on all platforms. In Carbon
specific code, Boolean is still used because the Carbon header files
define it to unsigned char.
- this fixes bug [ 623152 ] MacOSX: Triple Exception Booting win95.
The bug was that some code in Bochs depends on Boolean to be a
32 bit value. (This should be fixed, but I don't know all the places
where it needs to be fixed yet.) Because Carbon defined Boolean as
an unsigned char, Bochs just followed along and used the unsigned char
definition to avoid compile problems. This exposed the dependency
on 32 bit Boolean on MacOS X only and led to major simulation problems,
that could only be reproduced and debugged on that platform.
- On the mailing list we debated whether to make all Booleans into "bool" or
our own type. I chose bx_bool for several reasons.
1. Unlike C++'s bool, we can guarantee that bx_bool is the same size on all
platforms, which makes it much less likely to have more platform-specific
simulation differences in the future. (I spent hours on a borrowed
MacOSX machine chasing bug 618388 before discovering that different sized
Booleans were the problem, and I don't want to repeat that.)
2. We still have at least one dependency on 32 bit Booleans which must be
fixed some time, but I don't want to risk introducing new bugs into the
simulation just before the 2.0 release.

empty pathnames, zero cylinders, etc. It doesn't seem fair to allow
people to write out bochsrcs that they cannot read back in without
patching them up by hand!
- in harddrv.cc add the equivalent checks with BX_PANICs so that at least
we don't start simulating with incomplete device configuration.
- make a few error messages more clear

I got Win95 running with 32-bit paging/filesystem using the
recommended driver and these patches. Since the patches did
such a good job bracketing code modifications with a #define,
they might as well become part of the current CVS code.
