What's the best and most cost effective way (preferably free) to reset my Compaq Presario 2500 BIOS password? It's a laptop and my BIOS is Phoenix v4 release 6.

If you cannot remember the old password then you will prob have to open up the laptop and use the clear CMOS jumper/take out the battery.

That is, if there is a jumper. If not, remove the battery from the board. Would flashing the BIOS, erase the password?

They often have backdoor passwords into BIOSes.

I have a fairly old document that says the Phoenix ones are:
<b>phoenix</b>; <b>PHOENIX</b>; <b>BIOS</b>; <b>CMOS</b>
But it is rather old...

It also lists a way of using DOS's DEBUG.EXE to trash the CMOS, thus clearing the password (coincidentally, I actually had to do this earlier to a PC a customer had sent in.), but for that you need DOS (Or presumably 9X in DOS mode). I doubt it would work with XP/2000 (Which I assume you are using)

We can drop the subject now... I sold the laptop long ago.
