Run DOS Programs in WinXP

[Nuno Gomes]

Hello all,

I have a question to do:
The DOS only read/write in a disk with a max capacity of 2Mb.
Using the Windows XP to run DOS programs in a disk with 40Gb what happens?
When the data in the disk go over 2 Mb the CLIPPER's programs works without
problem?...




Thank you for your help.

Your statement "The DOS only read/write in a disk with a max capacity of
2Mb." is unclear. Are you referring to the maximum file size? Diskette size?
Disk size? And where did you get this 2 MByte limit from?

I'm referring to the hard disk size.
Has far i know, the DOS only is capable to use a 2 Mb of disk size...

But i'm running a DOS program in Windows XP, so when the data in the hard
disk become mode than 2 Mb what happens?...


Thank you for your help.

That's news to me. I remember running a Novell Server on a DOS 3.x
backbone and my disk size was 60MB. I think that what you are thinking
about is the FAT16 2GB partition size limit. This is a non issue, you
can install and run DOS programs on the same disk that is hosting the
operating system, with Windows 2000 this is usually an NTFS disk well
over 2GB in size! The NT Virtual DOS Machine will present the disk to
the DOS applications in a manner that the applications can understand.

I think you should check your facts. We had a DOS 6.2 machine in 1987 and it
had a "huge" disk of 20 MBytes, ten times more than the limit you quote.
However, there are a couple of limitations under some versions of DOS 7
(=Windows XP):
- Maximum partition size: 32 GBytes (Gbytes, not MBytes!)
- Maximum file size: 4 GBytes
There are some third-party tools that let DOS 7.0 recognise partitions large
than 32 GBytes.
