I recently bought a Presario 5WV254 at a yard sale, and I can't access the CMOS and BIOS upon start up, as I do with any other computer.

1. I need to change the booting sequence to floppy, cd, then
hard drive, as opposed to its existing configuration.

2. If I am able to toggle it, I'm asked for a password I don't
know.

Does anyone have any suggestions? Thanks.
