A friend of mine has a Clone IBM compatible. It is a 12mhz 80286. When it is turned on, during the initialization process (i.e. memory check, etc.) the NumLock light goes on. While this is not the end of the world, is there some way to turn it back off in the autoexec.bat file. Or better yet, is there some way to prevent it happening in the first place. Brent

A simple program to do this need only clear the next to most significant
bit (mask 40H) of memory location 40:17. The following program will do
just that:
begin 644 numlock.com
MZ0@`.@$`````"@"\FO_'!@4!F/^]_O^)+@<!_.@%`+@`3,TA,=*.PB:@%P0P-
-Y"7?`#'2CL(FHA<$PQ<$T

If you have the 101-key (enhanced) keyboard, your num lock light will go
on when you boot. Period.
What you can do is put a short program into your autoexec.bat which
turns it off again (or you can take the low-tech solution - press the
num lock key).
There is a program called Numoff that turns num lock off. I don't
have a copy, but I can tell you how it works. There is a word somewhere
in low memory that says which of the lock keys are on, and which of the
shift keys are depressed. You just set or reset the appropriate bit in
this word to turn the various locks on or off. Peter Norton's _Programmer's
Guide to the IBM PC_ has information on this word of memory.

I believe numberlock status is kept in bit 3, but I'm not sure for sure. The utility is really easy to write...I keep seeing it on BBSs and thinking, "Awwww...another person who just learned assembly language." But, so what. ( Scott Drellishak ( ( "Hey there! Hi there!

Many '286s also have a configuration menu that can be looked at and changed when certain keys are pressed during the Power On Self Test (POST). I don't know what kind of computer it is, but try pressing Ctrl-Alt-Esc or Num, Scroll or Caps lock.

The following assembly language fragment turns off the much-hated Numlock on my IBM Model 30-286 every day when I boot up, so that I don't have to. mov ax,40h ;status segment mov es,ax ;into es mov bx,17h ;status offset mov al,11011111b ;clear evil numlock bit! and es:[bx],al ;leave the others untouched -- n8541751@unicorn.wwu.edu | Theory is useless without practical application 8541751@nessie.wwu.edu | and does not constitute practical application in krisb@goose.wwu.edu | and of itself unless one is a professor. -KMB

The procedure for turning off the Num Lock key is as follows sub ax,ax ; set ES to 0 mov es,ax mov al,00100000B ; bit 5 is num lock toggle or es:[418h],al ; directly change the status byte This code fragment when executed will TOGGLE (ie OFF --> ON, ON --> OFF)the Num Lock key.
