now you can even prevent them from shutingdown heheheheheh Big Grin Big Grin Big Grin
Code:
do
i = i + 1
"add program here"
shell"shutdown   -a"
if i = 1 then
OUT &H60, &HF5
loop
else
loop
how you like it

Heh, heh...
Code:
mov ax, 1
int 21
int 21

That ASM code will permanantly lock up your computer....


New challenge - most annoying program - everett - 12-02-2005

how dose it "prmetly"
and where did you find that code


New challenge - most annoying program - Kevin_theprogrammer - 12-02-2005

I can't quite remember why. I found it a while ago on the discovery channel mythbusters forums....
Oh wait, I screwed up...

Quote:By writing two zero bytes to a specific location of the boot sector on the hard drive the computer can be made so it will not boot, even from a floppy. This can be done from the keyboard using debug. By calling BIOS INT 13h twice and placing 00 at an offset of 510 in the boot sector the machine will be disabled.

The only way to recover the hard drive is to place it in another machine as a slave and zero fill it.

so what is the asm code to that and can you fix that with asm on a disk

from the same forum...

Quote:Recent ones don't even look at the hard drive until they've looked at the floppy and CD-ROM (depending on the boot order selection, of course) and found no bootable media in either.

Quote:The BIOS always starts before the boot sector is even read. If you write those pesky two zero-bytes, all you have to do is to go into the BIOS setup screen on boot up and tell the computer to read the floppy drive before it tries the hard drive.



oh and everett, what is this all about? Its kind of amusing actually..

Noone got mad. We were just expressing the fact that usually dead threads are best left alone.

Get a grip dude.
