Aha! The list is back up!
For the record: CT50, 32M, IBM 20G. My partition info - no problems yet, but
I'm cautious, so I left space either side of the 8G break...
Disk /dev/hda: 255 heads, 63 sectors, 2432 cylinders
Units = cylinders of 16165 * 512 bytes
Device Boot Start End Blocks ID system
/dev/hda1 * 1 1014 8144923+ b Win95 FAT32
/dev/hda2 1015 1019 40162+ 83 Linux
/dev/hda3 1029 1063 281137+ 82 Linux swap
/dev/hda4 1064 2432 10997492+ 5 Extended
/dev/hda5 1064 1318 2048256 82 Linux
/dev/hda6 1319 2432 8948173+ 82 Linux
Which leaves a gnat's under 40 meg either side of cylinder 1024. One of
these days I'll get round to examining what's in there and see if I get the
same results.
