[DOS Programming] Get Free Memory

[MMoeller]

Hello to all,

I do i programmatically get the free conventional, XMS, XMA and EMS Memory ?
Which function (interrupt) must i call ?

I'm about writing an System Information Utility.

Thanks in advance,
Martin

Google is your friend. It's all out there, and not hard to find ...

Use this forum for problems and advanced techniques that are not so easy to find.

agree with Mike. but i will point Martin to the best resource there is on interrupt calls. the Ralf Brown interrupt list...

that should be just about everything you need. in the future, please use Google for this sort of thing.

The wolf3d source code release has some code for determining XMS/EMS free memory.
