You are supposed to use the d0p* devices; the "raw" disks are visible as well, but this is mainly because my attempts to "hide" those so far resulted in evil side-effects. > Also, there is a boot message right before the first PDC20265 that says: > "ide: Assuming 33MHz system bus speed for PIO modes; override with > idebus=xx" This is a bit of a confusing message. It means to say that it assumes the _PCI_ bus is 33Mhz as it bases some timings for PIO (not DMA) modes on that. > Is that for the CDROM on ide1(master) or that for the RAID ide's?
