Jim,
DiskEdit shouldn't work since I assume it is assuming the blocks are 512
bytes rather than 2048 bytes per sector. CD-ROMs are usually 98% of the
time 2048 byte blocks.
Basically the MSCDEX should just give it a letter. I doesn't mean it is a
networked drive … for example ram disks aren't networked. Also in the
case of Novell Networks they have a completely different filesystem and
intercept all the disk calls and handle them appropriately.
Another word about Norton … ISO-9660 is SIMILAR to MS-DOS in many
respects but it has many parts that are different enough to cause problems.
ISO-9660 doesn't have a fat like MS-DOS. The boot sector usually is sector
16 (logical) rather than 0 as under DOS. Directory entries give absolute
sector locations on the ISO-9660 while MS-DOS give offsets into the FAT.
