Gleb, have you seen this thread?
Some of the recent changes to smbios that look like possible culprits
are:
Make SMBIOS table pass MS SVVP test
Use MaxCountCPUs during building of per cpu tables.
Add malloc_high/fseg() and rework bios table creation to use them.
There were other changes, but the comments indicate they were only
ports of changes already in bochs. I suppose it's also possible the
lack of smbios is turning off some other feature in the guest (eg,
acpi) that's the real culprit.

[PATCH] support piix PAM registers in KVM
by Gleb Natapov
Without this BIOS fails to remap 0xf0000 memory from ROM to RAM so writes
to F-segment modify ROM content instead of memory copy. Since QEMU does
not reloads ROMs during reset on next boot modified copy of BIOS is used.

To be honest, this has never really been done before in SeaBIOS, so I
think we'll have to figure this out as we go. Since you need to
access full memory, it looks like it will be required to jump into
32bit mode.

This sounds okay to me - it should be possible to implement
handle_1abb(regs) which does a call32(tcg32_1abb, regs). It's
possible to do all the pointer conversion while in 32bit mode.

This shouldn't really be an issue. The build should take care of
this.

I can't say for sure what will make sense without seeing the code
first, but it sounds okay to me.

[PATCH 0/9] Misc boot related cleanups
by Kevin O'Connor
Some cleanups I came across while reviewing the boot code.
Gleb - patch 7 conflicts with your last patch - I hope it isn't a big
deal to fixup though. (I'm still reviewing your last patch.)
-Kevin
Kevin O'Connor (9):
Rename add_ordered_drive() to add_drive() and use in map_hd_drive().
Call setup_translation() from map_hd_drive().
Don't access drive_g->desc from boot_cdrom().
Remove Drives global struct in favor of independent global variables.
Move IPL.checkfloppysig to a global (CheckFloppySig) in boot.c.
Move IPL.bev to static variables in boot.c
Move IPL.fw_bootorder to static variables in boot.c.
Minor reorganization of some of the boot_xxx code in boot.c.
Remove drive->desc field.

[PATCH] USB boot priority
by Kevin O'Connor
This adds tracking of USB port paths, and enables searching the
bootorder file based on it. It's on top of the other patches I've
sent.
Gleb - I tried adding:
-usb -drive file=dos-drivec,if=none,id=d1 -device usb-storage,drive=d1,bootindex=1
But qemu didn't add anything to the bootorder file. (It does register
the usb drive.)
