Hi,

I'm looking at a generic Celeron notebook ('Advent 5372', Celeron 700,
XP/SP2) that has a Toshiba MK6015MAP hard disk on an SIS controller.
The drive is ATA-5 and supports Ultra DMA transfers of 66.7MB/s, but
the BIOS recognises it as 'MODE 4', rather than 5 (is this right ?),
and on the Advanced tab of the Primary IDE Channel properties it's
showing up as "DMA if available" and "PIO Mode" for the current mode.
The "Device Type" field is greyed-out, showing "Auto Detection".

Could someone help me get Windows to use DMA here please ? I've tried
reinstalling the controller, but it always reverts to PIO mode.

Should the BIOS see this drive as Mode 4 or 5 ?

Many thanks,

Cheers,

Kev.

Win does that with a drive that it sees a significant
error rate on the cable with, for safety of the data.

Presumably the cable is defective but there
can be a small adapter with notebooks.

Doesnt really matter much with laptop drives.
