Isn't that what it's there for? In any context other than save/restore I
wouldn't think using the BIOS was a good approach. But this is a special
case,
I added Kendall from Scitech to the CC list. He is the expert on
getting VBIOS's to post. Maybe he can help.

It also explicitly states that Windows 2000 and XP don't support this,

BTW it seems that old ATI cards use the BIOS to initialize secondary

This works well in many cases, but there are some machines that freeze

hi all,
I would like point to work done by Li-Ta Lo.
It allows you to completely initalize the VGA BIOS w/out using
PC BIOS at all.

We know that all of these ROMs are run at power on so they have to

Perhaps only emu86 should be used, to have a well-debugged codepath on
all archs (amd64, ppc, ...)
As it's usermode, the code size is l

Very bad for debugging. Genuine serial ports are becoming rarer.

We already try to do that, but it hangs on 70% of machines. See

Well, it is made more tricky by the fact that you are running during
resume -- hard to debug. Ideally you want to have video so you can

wakeup.S runs in real mode. Why can't it just call the VBIOS at
C000:0003 to reset the hardware before setting the mode?

Reseting a video card from suspend is essentially the same problem as
reseting secondary video cards on boot. The same code can address both
problems.
Some things to consider
1) With multiple video cards you have to ensure only a single VGA gets
enabled. Running video reset on a card is going
