[comp.sys.ibm.pc] Hard Disk Partition Types

andyross@ddsw1.MCS.COM (Andrew Rossmann) (01/17/90)

  I have written a program that reads the partition table, and displays what
type of partition(s) you have. So far, I've been able to identify the
following (all values in hex):
00=none
01=12-bit DOS
02=Xenix
03=Xenix (any different from 02??)
04=16-bit DOS, 32M limit
05=16-bit DOS, extended partition (<=32M)
06=16-bit DOS, >32M
08=Split (??)
51=Disk Manager
56=GB (??)
61=Speedstor (?)
64=Novell
75=PC/IX
DB=CP/M
FF=BBT (?)

  The ones marked with (?) I'm not so sure of, or what they actually are.
  I would be interested in knowing of any other partition values.
  Does anyone have information on how Disk Manager (and maybe others)
allows up to 16 partitions? How do I read the logical disks inside a DOS
extended partition? What is the exact format of Partition entries?
