Hi everybody,

My OS/2 Server runs usually pretty stable, but I am using a software that has Problems with more than 64 MB of ram.
In fact, my Software runs about 10 times slower with more than 64 MB RAM.
I think the software has a problem in adressing the memory area above 64 MB.

So IŽd like to limit the usable memory in OS/2 to 64 MB, even if I install 1 GB Ram.
The MB option OS/2 > 64MB is not a solution.
Maybe anybody knows a line for the boot.ini, or the os2.ini which limits the usable memory area to 64 MB. ?

Well, the thing about the software sounds curious, but it is fact. This thing was written in a time, 32 MB was pretty much ...

Thanks,

Thomas

This Problem is so old like OS/2 Warp.

Older BIOS versions have a Switch to set the RAM-accessing mode above 64 MB(OS/2 or Non OS/2)

In newer systems the BIOS constructors have removed this switch (the "designed for windows" certificate is depended on this).

The only way to fix this problem is to patch the os2ldr in the root directory of the boot partition.

A very good tool you can find on
http://hobbes.nmsu.edu/cgi-bin/h-browse?dir=/pub/os2/system/patches/

the filename is "patchldr.zip"

Thanks Daniela Engert for this very good software.

Make sure you have a copy of the old OS2LDR and a bootable diskette ,if the patch operation fails is this the only way to repair the system.
