No.  The case I cited was for a PS/2-70-121 (120 MB fixed disk); I'm typing
this on a NEC PowerMate which has two physical fixed disks of 40 MB each.
Installing MS-DOS 5 on this unit did *not* reconfigure the FAT.  It's 
still in DOS-16 format.  I haven't tried DOS5 on any otherm machine with 
120 MB of fixed disk or larger, so I have a sample population of one.

BTW: both the PS/2-70 and the NEC were partitioned using the standard 
FDISK program.

I haven't gotten around to calling uSoft to see just why this happened.
