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. > >Such people do exist.

One of the disk partition packages at the office, probably the software
distributed by seagate with their new disks, and/or Ontrack management
software, showed PCIX partitions to be something like #117.
In the middle of the night, I thought I remembered reading that Minix was
written under PCIX. Separately, I heard that PCIX is orphaned.
So naturally I use that partition number.
I would welcome corrections on any of these opinions...

I picked 25 decimal (0x19) as being small enough to not be hit by other "way out" number pickers, and large enough as to miss IBM's list. Perhaps 07 is the new OS/2 file system (the BSD version of OS/2 ;^). You know, with long file names, contiguous files, etc.! > Douglas Thompson UUCP: ..{tektronix,ogcvax,uunet}!sequent!norsk > Sequent Computer Systems Phone: (503) 526-5727 > 15450 SW Koll Parkway !"The scientist builds to learn;the engineer learns in > Beaverton OR 97006 !order to build."
