hi ya guennel
ata (sw) raid works fine....
- fastrak100 may or may not be a problem...
fastrak is NOT listed in the list of "hw supported raid"
http://www.linux-ide.org/chipsets.html
( donno how current it is
( or the definition of "working/supported" hw raid5 )
in the lilo.conf files...
boot should be boot=/dev/md0
so that you can boot off the other disks
root should always be root=/dev/md0
you'd need an initrd with raid support
you know raid is working when you can pull out any of the disks
and the system still boots and works... works at least in degraded mode
- if you did not pull out the disk or pull out the ide cables
( it might not yet be configured correctly

x> /dev/hde2 none swap sw 0 0
x> /dev/hdf1 none swap sw 0 0
x> /dev/hdg2 none swap sw 0 0

i think /boot should be in the first 1024 cylinders...
and similarly for /
- i always use /boot as the same as / partion
- no point in having /boot separate of / is corrupt
-- i dont understand why you have raid0 and raid5...
it make sense if...
raid1 ( mirroring ) is used for booting off
either hda or hdc disks
and stripping hda->hdd and hdc->hdb
raid5 is used for /home or /opt ( user data )
