Looking for info about INT12h, mem tools and copy tools (Miscellaneous)

There's an old FASM thread titled How to determine amount of free conventional memory? that may help.

For instance, I pointed to a download link of TSRW31.ZIP that had FREERAM.ASM inside it. But I don't recall how accurate it was. (Maybe it's only largest block?)

I do have some old "walk the MCB chain" code I found in a Turbo C book somewhere (but not sure of the license).

You could also just use Turbo Pascal "writeln(memavail);", and then disassemble that to see how it's done. That's usually pretty accurate, IMHO. Actually, even better, just use FreePascal's code (sorry, don't know the exact filename): rtl/i8086
