Comment:

Having a problem with IBM PC DOS 2000.

When I insert the following lines into config.sys:

device=c:\dos\himem.sys
device=c:\dos\emm386.exe noems
dos=high,umb

It deletes itself or corrupts itself badly after a few file operations (copy/move, etc).

The machine is ~2.5 years old. 3.2 GHz P4 with 2 gigs RAM.

DOS is being installed on a 2 gig partition at the start of the drive.

Anyone got any ideas?

PC-DOS has a built in memory configuration tool, run RAMSETUP.exe from the command line.

Thanks for the reply.

I ran ramsetup, and it still ate itself. This time it was a bit quicker.

Is it a problem that I have 2Gb of RAM installed in this machine?

MS-DOS doesn't seem to have any problems. It's just PC-DOS giving me these headaches.

RAMSETUP configures the settings for you, therefore no need to manually tweak!

I know. I didn't manually tweak anything.

It still corrupted itself.

The only trick is to look in BIOS and see if it has an option for less than 64MB Mem OS/2...

MS-DOS 6.X only recognises 64 meg of ram that's why that works fine.

Thank you.

I'll have a look through my BIOS settings. Hopefully there's something there.

Failing that, are there any patches available for PC DOS to allow it to work on machines with more than 64mb RAM?
