Doesn't matter. The kernel mounts the root and the others are mounted
when fstab is read (root is already mounted at this point).

You could probably make it work OK by using initrd and loading the module
with the script, but compiling in support would be much more straightforward.

Can anyone tell me if there are any problems using this card in a linux
HW-raid?
Thanks

Also how big of a raid partition is possible? I have a data partition need
of 36 gigs plus.
Just need to know how hard it is to move from software to hardware
raid. Would I have to reformat the HD's? Any special considerations?

The other is that lilo is not properly configured -- I've seen that

Do you have your kernel built for auto raid start?? and partitions marked

You can reconstruct you existing array by booting with a kernel that
supports raid and with the raid tools on the rescue system. Do it all the
