I upgraded to 2.4.19 and my /dev/hda became /dev/hde which caused various boot problems, which I worked around. It seems clear that upon booting 2.4.19, the newer kernel recognized the "other" IDE controller on the MB, which 2.4.19-pre7-ac2 had not. The manual that came with the MB said to use the IDE slots marked IDE0 / IDE1 if I wasn't going to use RAID. If I wanted to use RAID use the slots marked RAID0/RAID1. I was just wondering how linux decides which controller is first (hda-hdd) and which is second (hde-hdh).
