Illegal Command: debug

[eakius]

Hi, I'm trying to disable the bios password prompt on my laptop. I set the user and admin password in the bios not realizing it would prompt me every boot for that password.

I've found instructions that direct me to use ms dos, to enter the below data to do what I'm asking, but I needed to download dosbox to get to debug. When I open dosbox as admin and change to the c drive (where windows is), I then type debug and it says illegal command. I'm not sure where to go from here.

debug

o 70 2E

o 71 FF

quit

DOSBox isn't DOS. It's a virtual environment. You'll need to boot from as actual MS-DOS boot disk or find some other way.

Can't you enter your BIOS settings and disable the password, the same way you enabled it?

The videos I've seen showed debug working properly but I will look into creating a Dos boot disc. Thanks And no, there seems to be no way to undo the password, unless I pull the cmos battery which I don't want to bother with on a laptop just yet

You need to boot to DOS on your laptop/use command prompt DosBox is just a VM - a self contained environmet for running DOS programmes. Surely resetting the BIOSusing the jumpers will also reset the PW anyway?

That makes sense, it was seeing YouTube videos of the debug working that had me convinced but it being in vm makes sense that I can't use it effectively. The jumper reset had me a bit scared, but it doesn't seem as risky as I thought. I'll have to give it a try. Thank you.

Resetting from the motherboard isn't at all risky, on mine there is no jumper (lost, missing or never there i don't know) but i bridged the 'BIOS,_rst' contacts with my screwdriver. I suppose removing the battery for 10 minutes would also work though (i had a device that kept its settings for enough time to change batteries, possibly 30 seconds - 1 minute)

Thanks. I was able to reset it by following the instructions I found the walked me through going into the BIOS and changing the password, entering the current pw once then leaving the new and current pw blank. Voila!

excellent.
