You may also need to enable support for the specific chipset on that
motherboard in your kernel config. See
ATA/IDE/MFM/RLL support --->
IDE, ATA and ATAPI Block devices ---> IDE chipset support/bugfixes.
Some fooling around with lspci, dmesg, and/or your motherboard's
documentation may help you figure out which option exactly you need.
