This is a list of changes which are in the CVS tree but not in the latest
release (1.1.2 bugfix3).
<ul>
<li> Fixed BX_PANIC_IS_FATAL bug, described below. Also fixed bx_panic bug that would silently discard panic messages if the logfd had not been opened yet (such as while parsing .bochsrc).
<li> implement diskd (second hard drive). You cannot have both a diskd and a cdromd
<li> applied Todd Fries' patch to add support for 2.88 floppy image
<li> applied Todd Fries' patch to do software reset instead of panic
<li> implement diskd (second hard drive). You cannot have both a diskd and a cdromd.
<li> latest bios version is now BIOS-bochs-2001_0517. This bios is required to use two hard disks.
<li> enable newharddrivesupport by default. This was needed for ATAPI CDs, disks larger than 528MB, and maybe other things. It seemed like every time I had a wierd disk detection problem, it was because I had forgotten newharddrivesupport.
<li> add --with-term GUI mode. uses text mode display only
<li> add --enable-split-hd. Split hard drive mode allows several partial disk image files (e.g. win95-1, win95-2, win95-3) to be treated as one large file, so that you can store each partition in a separate file, if you get the file sizes to match the partition table boundaries. Split hard disk patch requires a new rombios, BIOS-bochs-2001_0509.
<li> patches sitting in patches subdirectory:
<ul>
<li> patches/patch.lba. we have a patch to add LBA support, which Bryce grabbed from the plex86 source tree. I know that it compiles. But can someone suggest how to test it?
<li> patches/patch.4meg-pages. Again, we just need a test case. Once we can test it, I'll put it in.
<li> patches/patch.goswin-changes. These are diffs against 3/25/2000, and not all of them apply anymore because of our bug fixes.
</ul>
</ul>
There are also two active branches in addition to the main branch,
BRANCH-smp-bochs and BRANCH-io-cleanup.
<ul>
<li>
The SMP bochs branch allows
Bochs to simulate a multiple processor machine. It does NOT make Bochs
perform better or run in different CPUs on a real SMP machine. This branch
will be integrated into the main source tree in the near future. It has
not been tested much since REL-smpbochs-04-03-2001, but has most of the
same bug fixes and features that the main branch had on 5/8/2001. Est. time
frame to merge: next weekend 5/20.
<li>
The I/O cleanup branch was created 5/10 by Todd and Bryce, who are working
on revamping the bochs logging code. Since this involved so many files
and several commits, we are working on a branch to keep the main code
clean until the new I/O code is ready. Time frame to merge: end of this
weekend (5/13).
<ul>
There is also one active branch in addition to the main branch, called
BRANCH-smp-bochs. The SMP bochs branch allows Bochs to simulate a multiple
processor machine. It does NOT make Bochs perform better or run in different
CPUs on a real SMP machine. This branch will be integrated into the main
source tree in the near future. It has not been tested much since
REL-smpbochs-04-03-2001, but has most of the same bug fixes and features that
the main branch had on 5/8/2001. Est. time frame to merge: next weekend 5/20.
