Sorry, yes:
Asus A7A266 m/b (o/b sound),
AMD Athlon 1.4Ghz,
256Mb DDR RAM,
40Gb 7200rpm h/d,
ATI Radeon AGP 32Mb.
Other h/w I have is: floppy, cd-rom, cd-writer, mouse, k/board. No PCI cards used.
I found a revision of the m/b BIOS which has this change:
'Add ATI AGP display card patch to fix that the system can not execute AGP cycle with ATI AGP display cards.'
But I don't know what this means

and I'm not sure if it will help (?)
Thanks
