Can someone please explain this VGABIOS Error

[David Aubin]

Hello,

I got the testbios built and tried it and got the following error
doing:
./testbios -d 0x200 -t vgabios.bin

I made my vgabios.bin by doing:
dd if=/dev/mem of=vgabios.bin skip=1536 count=128

The error is:
c000:00dc 6e                  OUTSB
        AX=1cff  BX=ffff  CX=ff00  DX=60ac  SP=fff4  BP=0000  SI=0002

Can someone please explain this error to me and how to possibly fix it?

I have a Tyan mb with a 2885 chipset.  AMD64 chip.  And an Nvidia FX
5950 video card.
Any help would be appreciated:)

Thank you,
Dave
