I have found the following in my past lives on which OS's use which 
SYSID in the partition table:

	HEX
	00		Empty Partition Entry
	01		DOS 12-Bit FAT
	02		XENIX File System
	03		Old XENIX /usr File System, don't think used anymore
	04		DOS 16-Bit FAT
	05		DOS 3.3 Extended Partiton containing Extended Volumes
	06		DOS Large File System (512b sectors, ~32-bit addresses)
	07		don't know
	08		AIX, from above

	52		CPM - I belive, but not sure	

These I have found and used before. There must be others, but not sure.
Try a post to the comp.sys.ibm.pc for a request.

Numbers 1 thru 6 were IBM and MicroSoft. I think it is mostly defacto.
My suggestion is to select some number 'far enough' out to not colide
with future values.
