Hm, I think Turbo C 2.01 has a very tricky, and VERY ancient bug. The intr() function from <dos.h> header SHOULD be able to pass ES:BP pointers to interrupts. However I think it doesn't. Using this gives garbage (or probably: the stack pointer) to the interrupt vector instead. I wonder if this could be patched...? How hard can it be to disassemble the .lib files?
