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 ?
