since fedora wasn't running very stable at first I tried installing centOS and noticed that it detected my hardware differently.......
When installing F10 it recognizes my 160Gb system drive (IDE1) as sde (behind my 4 SATAII drives). CentOS recognized correctly that it is hda.
Can anyone explain why fedora picks it up wrong? It should be IDE1 (first boot prio) hda... right??
