I have got a 500Mhz processor on a Abit-BE6 II.
On this motherboard you have got 4 IDE ports.
IDE 1 & 2 are normal UDMA 33 ports that are adjusted via the normal bios.
IDE 3 & 4 are UDMA 66 ports from the HPT366 adjusted from a second bios.
apperently support for HPT366 controller is build in to kernel version 2.4.
Harddisks on the IDE 3 & 4 are therefor not detected by the SME 5.1.2
