[Freedos-devel] Idea about Virtual PC compatibility / A20 handling
Hi, Pavel Novy, author of some tiny tool which Tyler found useful, writes me some explanation for if you want to keep it tiny, then why does it start with mov ah,30h / int 21h (but does not do any- thing with the returned DOS version information)?. He found that the following code sequence would hang in Virtual PC: (com program) Start:jmp Begin XMSControldd? Begin:mov ax,4300h int 2fh cmp al,80h jne _errexit mov ax,4310h int 2fh mov word ptr [XMSControl],bx mov word ptr [XMSControl + 2],es mov ah,00h call dword ptr [XMSControl] _errexit: mov ax,4c00h int 21h Can somebody try to reproduce? Should we add some handling to our HIMEM / EMM386 for it? I think this is A20 related, something like disable A20 on exec() and reenable it again on the first int 21 call. Which is, by the way, a very useless feature: LOADFIX (should be part of every FreeDOS distro! Do we have one? It takes care to load programs outside the first 64k) is, as far as I know, taking care of possible program might expect wraparound at 1 MB in a better way. And of course I vote - again - for some HIMEM command line option switch A20 on at HIMEM start time but refuse to switch it off later. Thanks. Thanks to Pavel for checking his archives about the background of this use int 21.30 before releasing the environment of the program (which is where it was used in the binary found by Tyler) trick.

Hi, LOADFIX (should be part of every FreeDOS distro! Do we have one? LOADFIX is internal, and IIRC it is already implemented in FreeCOM.
