1. Way of topic: Assembly thing
Okay, this might not happen on everyone's systems, but it definitely has
an effect on mine. Here's the problem: whenever I write assembly progs,
sometimes I have to divide or multiply. But my computer goes crazy when I
use the (I)MUL or (I)DIV instructions. Once, a DIV instruction even rebooted
my system and damaged a FAT, all because I tried to convert a foreground
color into a screen attribute( background * 16 + foreground )! What gives?

BTW, my system is a 1997 Packard Bell Multimedia D141 with a Pentium-133
processor, 16 megs of RAM, and I was doing this in a DOS prompt in full
screen under Windows 95B

Maybe the instruction uses a register which has bad content? Or maybe the
problem
is left in a register by the div instruction, and the next instruction crashes
on it?
