The easiest way to upgrade from DOS 3.x to 3.3 is to do the following: 1 - Boot with 3.3 (on floppy) 2 - If upgrading from MSDOS to MSDOS then SYS C: If upgrading from PCDOS to MSDOS or MSDOS to PCDOS then remove the 2 hidden system files using Norton or PCTOOLS then SYS C: 3 - Copy various DOS programs over to the hard drive. 4 - Remove the floppy and re-boot. Although a complete format is really the "BEST" way this does work and I have done it on 3 different machines. Mark Warner UUCP: uunet!sdrc!diwarner SDRC Milford Ohio
