The motherboard is from "American Megatrends Corp" and it runs Award
Bios.
I am pasting below info from dmesg below:-

ad2: FAILURE -READ_DMA status=51<READY,DSC,ERROR> error=84<ICRC,ABORTED>
---------------------
sector 63 is where the first partition starts.
Both discs work perfectly in windows XP and the -and if there was a
cable/hw [roblem it would have shown during their functioning under
windows xp.
pl. let me know if you need any more info from the system.
thanks
