This is pretty typical of MS-DOS; it has a 504Mb
limit. There are a number
The 504M limit is BIOS, NOT MS-DOS.
But MS-DOS before version 3.31 had a 32M limit.
But the 32M limit did not apply to the network redirector. Therefore, to
handle CD-ROMs (3.10 and above), MICROS~1 provided MSCDEX.EXE, which made
the CD-ROM look like a network drive. Try a CHKDSK of a CD-ROM on MS-DOS
3.10 through 6.22 - it will say: "Cannot CHDSK a network drive"
(Worst episode of this fault I rememeber was using a
caching IDE controller
[expansion board with own memory] which reported a 1Gb disc, but wrapped
around at 504Mb - overwriting the boot sectors and root directory as we
wrote the 505th Mb...)
As easy as bashing MICROS~1 is, we can't blame the OS for BIOS or hardware
faults.
