I received a lot of responses to my posting about my DOS-upgrade trouble (see: DOS 3.21 --> 3.3 problems). Everyone noted that you need a large enough contiguous free space at the start of the disk to hold the new system files. I have DOS 3.3 running at this moment, but when I looked at the hard disk with Norton it turned out that MSDOS.SYS is *fragmented* ! It seems that the system files needn't be contiguous (any more) -- this should take care of the "not enough room" error message. Still, I got exactly that error when I first tried to transfer the system. A few days later, it suddenly worked -- immediately after a Speed Disk defragmentation (there simply could not have been any free room). The only thing I can think of is that the "media descriptor byte" (the first byte in the FAT) had a wrong value, and I fixed that a few days earlier. And now I have heard rumors about a "DOS 3.4"....... Another upgrade ? +------------------------------+ @@ @@ @@ @@ +-------------------+ | Rene' Baart | @@ @@ @@ @@ | EMAIL : | | Department of Economics | @@ @@ @@ @@ +-------------------+ | Free University of Amsterdam | @@ @@ @@ @@ | bagron@cs.vu.nl | | Amsterdam, The Netherlands | @@@@ @@ @@ | groedr@econ.vu.nl | +------------------------------+ @@@ @@@@@@@@@@@ +-------------------+ "..They don't call me ZAPHOD for nothing, you know.."
