executing code in 16-bit memory needs DosCreateCSAlias in doscalls #37

Open kerravon86 opened 9 months ago

kerravon86 commented 9 months ago

Under Windows 2000 I am able to run my 16-bit PDOS-generic with:

bios pcomm.exe

But with HX16 under Freedos like this:

dpmild16 bios.exe pcomm.exe

I am told that 0x2b (DosCreateCSAlias) does not exist in doscalls.dll.

Would it be possible to add support for this function?

Thanks. Paul.

Isn’t bios.exe a 32-bit PE? Why would you want to load it with dpmild16? It works once you use dpmild32.

Not sure why you think bios.exe (there's one famous one is there?) is 32-bit. I do have a 32-bit version too (multiple), but this was a question about the 16-bit one. You can see the NE signature below (and also see it running under Windows 2000 which supports OS/2 1.x executables).

DosCreateCSAlias() has been added to DOSCALLS.

Thanks a lot for that! Will give it a go in due course.
