I just recently installed linux redhat 9 on my computer. It is currently multibooting with windows xp.

I have my partitions set up as follows:

first hd:
40 gb NTFS (windows xp)
second hd:
10 gb fat32 (no os, just using for shared storage)
around 5gb ext3 ( redhat 9 )
something like 500mb swap space

I dont know much about linux, but I know that the last version I had tried (mandrake powerpack 9) could still see my fat32 partition.
However with my new setup I cannot see it? Can anyone possibly tell me how to see my other partitons?

What do you mean with you can't see them? Normally you need to load the module for the fs or mount the partition for it to be loaded automatically.
