And yes it uses RTM.EXE and DPMI16BI.OVL. But there's a twist - it includes a PE executable as well in the latest version. This latest version runs on XP (but only in 640*480...), but not on OS/2 (HXRT doesn't work). But HXRT on FreeDOS appears to solve both problems. >> When I try to run the executables, I get the error >> "Unhandled exception 000E at 0020 1AA4 ErrCode 0002" > > What memory managers are loaded?

I checked the DOS settings used in the OS/2 VDM, and EMS/XMS is limited to 8MB and DPMI memory to 16MB. >> 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. I will have a go. Sorry about the slow answer - I received your reply in a digest after several days, so I missed it.
