Another user on BTTR recently had a similar problem (again). His suggested workaround was "DEVICE=C:\FREEDOS\BIN\JEMMEX.EXE ALTBOOT MAX=32000 MIN=32000". Japheth (circa 2011) explicitly blamed the bug on Borland's DOS extender. His suggested workaround was this: " 1. Option /R63 for UIDE, which makes UIDE not use extended memory from the first 64 MB, must be set. 2. Option /X2MAX32 for HimemX, which makes HimemX restrict XMS v2 max. memory to 32 MB, must also be set.

Yes, obviously, Borland's old extenders weren't tested on modern machines. (BTW, how much total RAM do you have?) > But why does the error occur under FreeDOS? Running the same package in > an OS/2 or WinXP VDM does not produce the error. OS/2 and NTVDM both have separate DPMI servers that were tested differently. They usually throttle the amount of total RAM seen by DOS extended apps. > I have tried all three memory options from the boot menu - they do not > appear to change anything. It depends on how much RAM you have, and what options to the memory managers and extenders, and their versions, etc. Try one of the above suggested workarounds. ------------------------------------------------------------------------------ Don't Limit Your Business.
