ata0-master: DMA limited to UDMA33, non-ATA66 cable or device ata0-slave: DMA limited to UDMA33, non-ATA66 cable or device ad0: 58644MB <IC35L060AVV207-0/V22OA66A> [119150/16/63] at ata0-master UDMA= 33 ad1: 29311MB <Maxtor 5T030H3/TAH71DP0> [59554/16/63] at ata0-slave UDMA33 acd0: DVDROM <TOSHIBA DVD-ROM SD-M1202/1020> at ata1-master PIO4 This despite both the drives and 80-pin cables are supposedly ATA100 capable. Tried several cables which make Leenucks and Windows XP pronounce the drives as operating in UDMA5/ATA100 mode and the BIOS of the Intel D850GB board says the cable is 80 conductor and the Ultra DMA mode is 5. Atacontrol refuses to set the drives beyond UDMA33. 5.4-RELEASE, GENERIC kernel. --=20 Juha
