Re: mounting extended or logical partions
the Windows is Windows ME. They were partitioned with fdisk from Windows,
hda was partitioned with fdisk from me, hdb with win95. fdisk says they are
fat32. Since the original portioning was done, I ran a somewhat out of date
copy of Partition magic on the first disk to partion the linux partions root
and swap, but didn't alter the other partions.
