Hi all, I have installed a Promise TX2 Ultra ATA/100 controller into my Alpha pws 500au. The kernel seems to probe and attach a driver to the device: /var/run/dmesg.boot .... atapci1: <Promise TX2 ATA100 controller> port 0x8100-0x810f,0x8110-0x8113,0x8120-0x8127,0x8130-0x8133,0x8140-0x8147 mem 0x80914000-0 However, further into the process of booting, when the ATA driver is attached to ad0 I get these errors: Timecounter "alpha" frequency 499864662 Hz ad0: UDMA ICRC error reading fsbn 78165297 of 0-3 (ad0 bn 78165297; cn 77544 tn 15 sn 0) retrying ad0: UDMA ICRC error reading fsbn 78165297 of 0-3 (ad0 bn 78165297; cn 77544 tn 15 sn 0) retrying ad0: UDMA ICRC error reading fsbn 78165297 of 0-3 (ad0 bn 78165297; cn 77544 tn 15 sn 0) retrying ad0: UDMA ICRC error reading fsbn 78165297 of 0-3 (ad0 bn 78165297; cn 77544 tn 15 sn 0) falling back to PIO mode ad0: 38166MB <WDC WD400JB-00ENA0> [77545/16/63] at ata3-master PIO4 I'm worried about the line "falling back to PIO mode". Does this mean that ad0 is running at ATA33 ? I'm not sure if or how the ATA disk and ATA controller are related to causing the ATA disk to go into PIO mode. Can anyone sugest a solution to get the disk to usemode rather than PIO mode ?
