My dmesg says this: hda: 78165360 sectors (40021 MB) w/1024KiB Cache, CHS=4865/255/63, UDMA(33) To clarify myself, I know my drive supports UDMA 100...do I have to specify this in Linux itself, and if so, what/where does it go? If not, I assume it's in the BIOS? Thanks again! Chris > Viestissä Maanantai 2. Joulukuuta 2002 03:45, Christopher Taylor kirjoitti: > > OK...where exactly does one change the hdparms at?
