Hi,
Thank you:) Yes, it was at 0xc0000-0xc7fff, which is only 32k.
But the image I got from the windows tool was 64k (double 8000).
Weird. I would like to stay away from window tools.
The info you provided is nice. I wish there was a way for us
To make a faq and we could add this to the testbios faq. There
Is a lot of good info on the clustermatic list, but it is all
Dispersed.
Ron if I write a simple faq can you provide some mechanism to
Allow updates to it?
Thanks,
Dave

I was wondering about your dd command that but I had not had a chance to
respond yet.
This is what I use:
dd if=/dev/mem of=vbios.bin bs=1k count=64 skip=786432
That will rip the bios from 0x0c0000. You can verify that you actually
have bios there with
'hd -s 0x0c0000 -n 256 /dev/mem'
in some cases it may be located at 0x0e0000 rather than 0x0c0000.
It should start with the 0x55aa (Little endian) or 0xaa55 (big endian)
and futher on you should see some text identifying the bios.
