FreeBSD 7, no problems, just enable hw.ata.ata_dma_check_80pin and most of the problems go away; still a slow PC with faster disks, but it all works. Recently, I've had to try this with FreeBSD 8 and both with/without ATA_CAM, it no longer seems to apply. >From -v probe... (aprobe0:ata0:0:0:0): SIGNATURE: 0000 ata0: DMA limited to UDMA33, controller found non-ATA66 cable (aprobe0:ata0:0:1:0): SIGNATURE: 0000 ata0: DMA limited to UDMA33, controller found non-ATA66 cable loader.conf definitely has hw.ata.ata_dma_check_80pin=0 So that check shouldn't even be happening. >How-To-Repeat: Use ancient hardware and a dodgy bridge to make it useful >Fix: >Release-Note: >Audit-Trail: >Unformatted:
