i'm running the kernel that comes with redhat 7.2. (i think its 2.4.7 or 2.4.9). i have an abit kt7 (i know it has a UDMA 66 controller).
i tried "idebus=66" but then dmesg said something about not being able to do that and to try "ide0=ata66" instead. so i tried that, and now dmesg | grep 66 shows: Kernel command line: ro root=/dev/hda5 hdd=ide-scsi ide0=ata66 ide_setup: ide0=ata66 VP_IDE: VIA vt82c686a (rev 22) IDE UDMA66 controller on pci00:07.1 VP_IDE: ATA-66/100 forced bit set (WARNING)!! hda: 78165360 sectors (40021 MB) w/2048KiB Cache, CHS=4865/255/63, UDMA(66) any idea what the warning is about? oh well, at least the last line says "UDMA(66)" now...=) christopher On Tuesday 13 November 2001 10:04 pm, you wrote: > On Tuesday 13 November 2001 05:14 pm, Gordon Messmer wrote: > > On Tue, 13 Nov 2001, christopher j bottaro wrote: > > > ide: Assuming 33MHz PCI bus speed for PIO modes; override with > > > idebus=xx hda: 78165360 sectors (40021 MB) w/2048KiB Cache, > > > CHS=4865/255/63, UDMA(33) > > > > > > but my hard drives are UDMA 100, how do i get them to run at optimal > > > speed? > > > > What kernel are you running?
