FreeBSD 4.5 release. dmesg shows ata0 #ATA 33 (no ATA 66 compliant cable), so both drives on that channel default to PIO mode. Do I need to use different cables? I was under the impression that default was DMA if possible. I suspect the default kernel in FreeBSD, or the configuration routines run during setup, are intentionally conservative, to accommodate users with older hardware. There's an "hdparm" command in Linux which can be used to reset these values; I'm not sure if FB has a counterpart, and I'm at work so I can't check, but I expect it does. --------------------------------------------------------------------------------->>>>>>>>> Can anyone help me with this problem re: FreeBSD?
