20050428 Disabling the "-fmove-all-movables" option in the configure
script, because it causes the compile to fail on OpenBSD/sgi.
20050502 Minor updates.
20050503 Removing the WRT54G mode (it was bogus anyway), and adding a
comment about Windows NT for MIPS in doc/experiments.html.
Minor updates to the x86 instruction decoding.
20050504 Adding some more x86 instructions.
Adding support for reading files from ISO9660 CDROMs (including
gzipped files). It's an ugly hack, but it seems to work.
Various other minor updates (dev_vga.c, pc_bios.c etc).
20050505 Some more x86-related updates.
Beginning (what I hope will be) a major code cleanup phase.
"bootris" (an x86 bootsector) runs :-)
20050506 Adding some more x86 instructions.
20050507 tmpnam => mkstemp.
Working on a hack to allow VGA charcells to be shown even when
not running with X11.
Adding more x86 instructions.
20050508 x86 32-bit SIB addressing fix, and more instructions.
20050509 Adding more x86 instructions.
20050510 Minor documentation updates, and other updates (x86 stuff etc.)
20050511 More x86-related updates.
20050513 Various updates, mostly x86-related. (Trying to fix flag
calculation, factoring out the ugly shift/rotate code, and
some other things.)
20050514 Adding support for loading some old i386 a.out executables.
Finally beginning the cleanup of machine/PROM/bios dependant
info.
Some minor documentation updates.
Trying to clean up ARCBIOS stuff a little.
20050515 Trying to make it possible to actually use more than one disk
type per machine (floppy, ide, scsi).
Trying to clean up the kbd vs PROM console stuff. (For PC and
ARC emulation modes, mostly.)
Beginning to add an 8259 interrupt controller, and connecting
it to the x86 emulation.
20050516 The first x86 interrupts seem to work (keyboard stuff).
Adding a 8253/8254 programmable interval timer skeleton.
FreeDOS now reaches a command prompt and can be interacted
with.
20050517 After some bugfixes, MS-DOS also (sometimes) reaches a
command prompt now.
Trying to fix the pckbc to work with MS-DOS' keyb.com, but no
success yet.
20050518 Adding a simple 32-bit x86 MMU skeleton.
20050519 Some more work on the x86 stuff. (Beginning the work on paging,
and various other fixes).
20050520 More updates. Working on dev_vga (4-bit graphics modes), adding
40 columns support to the PC bios emulation.
Trying to add support for resizing windows when switching
between graphics modes.
20050521 Many more x86-related updates.
20050522 Correcting the initial stack pointer's sign-extension for
ARCBIOS emulation (thanks to Alec Voropay for noticing the
error).
Continuing on the cleanup (ARCBIOS etc).
dev_vga updates.
20050523 More x86 updates: trying to add some support for protected mode
interrupts (via gate descriptors) and many other fixes.
More ARCBIOS cleanup.
Adding a device flag which indicates that reads cause no
side-effects. (Useful for the "dump" command in the debugger,
and other things.)
Adding support for directly starting up x86 ELFs, skipping the
bootloader stage. (Most ELFs, however, are not suitable for
this.)
20050524 Adding simple 32-bit x86 TSS task switching, but no privilege
level support yet.
More work on dev_vga. A small "Copper bars" demo works. :-)
Adding support for Trap Flag (single-step exceptions), at least
in real mode, and various other x86-related fixes.
20050525 Adding a new disk image prefix (gH;S;) which can be used to
override the default nr of heads and sectors per track.
20050527 Various bug fixes, more work on the x86 mode (stack change on
interrupts between different priv.levels), and some minor
documentation updates.
20050528 Various fixes (x86 stuff).
20050529 More x86 fixes. An OpenBSD/i386 bootfloppy reaches userland
and can be interacted with (although there are problems with
key repetition). NetBSD/i386 triggers a serious CISC-related
problem: instruction fetches across page boundaries, where
the later part isn't actually part of the instruction.
20050530 Various minor updates. (Documentation updates, etc.)
20050531 Adding some experimental code (experiments/new_test_*) which
could be useful for dynamic (but not binary) translation in
the future.
20050602 Adding a dummy ARM skeleton.
Fixing the pckbc key repetition problem (by adding release
scancodes for all keypresses).
20050603 Minor updates for the next release.
20050604 Release testing. Minor updates.
============== RELEASE 0.3.3 ==============
20050604 There'll probably be a 0.3.3.1 release soon, with some very
very tiny updates.
