RE: testbios loops?

[Dave Aubin]

Here is a dump of the following:
/usr/bin/testbios -s 65536 -d 0x200 --abseg /dev/mem
/usr/bin/nv6800gt.bin -t

I slightly different behavior with this incantation.  Normally I leave
off
The -d 0x200.  My device is located off of 2:0:0.

running file /usr/bin/nv6800gt.bin
No base specified. defaulting to 0xc0000
No initial code segment specified. defaulting to 0xc000
No initial instruction pointer specified. defaulting to 0x0003
