	GemDos is still limited to 16 Meg partitions.  Several of
the hard disk systems do allow you to create partitions larger than
16 Meg as long as the partition is *NOT* used for GemDos (ie. Spectre,
Minix, OS9, etc.).  Atari has not said anything about increasing the
16 Meg limit in the newer TOS releases.

	GemDos is also limited to 16 drives, A to P.  (NOTE: The
original doc said there was a 32 drive limit.)  Drives A and B
are used for floppies, leaving 14 drives for hard disk partitions. 
Atari's hard disk software only supports 4 partitions per physical 
drive giving a 48 Meg limit.  Supra, ICD and BMS all allow up to 14
partitions per drive, giving a 224 Meg limit.
