Default password backdoors?

Am going to install Ubuntu 5,04 (Hoary Hedgehog) on 2x HP BrioPC with mendocino 433 and PhoenixBIOS and 2x whitebox system with tualeron 1700 (?) and AwardBIOS. Does anyone know of any password backdoors for the BIOSes as they are all p/w protected and none of them have CD as first boot device.

You have to clear the CMOS (or password - brand machines usually have separate jumper for that).

Pull the battery out for a couple hours, that will discharge it, and erase any passwords. Of course you'll have to reset all the BIOS parameters also.

ubuntu 5.04 installed perfectly on the p4b533-vm. the Brio must have a capacitor backup for the memory as it still prompted a password after battery being disconnected overnight.

Get a manual and use "clear password" jumper or DIP switch.

Try the clear CMOS jumper - the usage is described here http://h10025.www1.hp.com/ewfrf/wc/d...cname=bph07169 (you need to turn the power on with the jumper in the "clear" position).
