I just tried to bring PC-DOS 3.1 up on my AT. DOS is the 4th partition on the disk. I already have 3.0 up and do NOT want to have to backup and reformat the whole disk (I trust the backup facilities in XENIX and PC-DOS about as much as I trust CS professors). I keep getting an error that there is not enough room on the system disk to bring the system up. This has to be a crock, I deleted until I had at least a meg of space. Does anybody have a fix so that I can update? -- liz sommers uucp: ...{harvard, seismo, ut-sally, sri-iu, ihnp4!packard}!topaz!sommers arpa: sommers@rutgers

Surely the problem has to be the usual one; the new DOS files take up slightly more room than the old ones, so it isn't possible to copy the new files (specifically IBMBIO.COM which has to be contiguous) into the space occupied by the old ones. Solutions are to reformat the disk (great!) or find out which files occupy the space needed by the larger files (although I am not certain this will work). -- Bob Eager rde@ukc.UUCP rde@ukc ...!mcvax!ukc!rde Phone: +44 227 66822 ext 7589
