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. Joe Morris
