PSP manipulation from DPMI programs (Developers)

posted by tkchia Homepage, 16.02.2023, 17:14

Hello Laaca,

By the way... depending on what Free Pascal's DOS extender does, you might be able to build the child process's new environment variable block in extended memory (without having to purposely place it into base memory (!)). The key thing will be to check how int 0x21, ax = 0x4b00 is handled.

Thank you!
