Strange thing. 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.
