BIOS Updates forum

I just pin-pointed what exactly is causing the problem, and it's not INT 13h. It's a simple divide! The line of code is: div WORD [SectorsPerTrack] Anyways, I don't know how much that means to you (I don't know if you know Assembly). I don't know why my one computer can't handle this divide...

If it was my code, then it wouldn't work on ANY computer. It just doesn't work on my one computer...

So what do you think could be causing my problem?

Thanks!

I really hope this is the right spot to ask this question... I'm writing my own operating system. And, I use a BIOS interrupt (0x13) that reads a sector off of a disk (in my case, a floppy) and loads that sector at a given address. Anyway, this works on all computers, except my one computer. And wha...
