Well... on my hard disk... with JEMMEX yes.

So I installed:
http://www.delorie.com/pub/djgpp/current/v2tk/allegro/all422ar2.zip (the
Allegro .h and .a files)
and:
http://www.delorie.com/pub/djgpp/current/v2tk/allegro/all422s.zip
(Allegro sources... mostly for the examples)
And I have compiled:
#include <allegro.h>
#include <stdio.h>
int main(int argc, char *argv[])
{
if (allegro_init() != 0)
return 1;
//printf("will install keyboard\n");
//install_keyboard();
//printf("keyboard installed\n");
//that worked (not break things), when uncommented
set_gfx_mode(GFX_AUTODETECT, 320, 200, 0, 0);
while(1);
return 0;
}
END_OF_MAIN()
with: gcc -o paul.exe paul.c -lalleg
expected result: change to video mode, and hang
obtained result: change to video mode and returned to dos, showing the path
(system very instable after)
If I put the while(1) before set_gfx_mode it hang in text mode, as expected.
I suspect it use int 10h to set video mode... and somehow int 10h does the
job... but does not return with the same full state (unclear what)._______________________________________________
