With previous version of kernel (2.4.1 I think), I haven't got this problem. May be a bios detection problem? Extract from /usr/src/linux/drivers/ide/via82cxxx..c: * * PIO 0-5, MWDMA 0-2, SWDMA 0-2 and UDMA 0-5 * * (this includes UDMA33, 66 and 100) modes. UDMA66 and higher modes are * autoenabled only in case the BIOS has detected a 80 wire cable. To ignore * the BIOS data and assume the cable is present, use 'ide0=ata66' or * 'ide1=ata66' on the kernel command line. * I've tried with ide0=ata100, but this options doesn't work.
