(re: Old games under DOS)
sounds very familiar – in my friend’s laptop, whenever you load ANY dos application (raging from Borland C++ 3.0 to dos games like Red Alert 1) it shrinks to about 3/4 of the screen, without any apparant reason. He tried to solve it but gave up in the end, probobly a hardware thing… (in any case, try to search your BIOS menu)
