Borland 32RTM 1.5 fails to work in FreeDOS but works in MS-DOS. I've patched it to make it work by modifying the byte at offset 284h from 0 to 1. The X32 DOS extender used in Digital Mars SMAKE had caused problems, so I've patched its offset 4707 from 23h to Bh, but right now when I test it, it works! (So somehow the bug got fixed during the last year ;-) Last not least, since it modifies the SFTs, the HiNTOS DOS extender (or Windows to DOS converter) doesn't work at all in FreeDOS. Alas, I did my patches more than an year ago and I don't remember how I found out these offsets :(

More specifically, I would need download access to an application which fails when running under these (or any) extenders, rather than the bare extender itself.


Without the context of the CPU instruction or data being patched and what the patch is meant to do, an offset and byte punch value is of no use for externally tracking down and correcting the underlying problem.
