bios e500
I don't know how easy this is with a Compaq laptop but with an AWARD BIOS I once ran the AWDFLASH program with all the clearing options, but also with switches to tell AWDFLASH not to program or backup the BIOS. I imagine the same could be achieved with UniFlash. It is the software oriented way in which I sucessfully cleared a BIOS password which is equivelant to the Clear CMOS jumper.
