Subject: UDMA 5 on Promise ULTRA 100

I run linux 2.4.2-ac24 on the ULTRA 100 card with pdc 20267 Chip.

Drives are MAXTOR 53073H4 UDMA100.

Everything runs fine so far. The only thing which iritates me is
that :

/proc/ide/pdc202xx reports that the drives run in UDMA4 mode.

I have the above mentioned drives running as master each as a single
drive on its interface.

How can I achive that the drives run in UDMA5 ?
