HP 486s/20 Bios Errors
Whenever i boot up my Hewlett Packard 486s/20 computer, I can hear the hard drive and all of it working, but it still gives me 0240, 0250, and 0130 bios error codes. I've made a makeshift external CMOS battery because that's what it takes, but it still doesn't seem to work. it says I need a Vectra #1 diskette. I have a floppy disk drive on my main computer, but I just can't find an image of it. I need a way to access the bios so I can edit the time and set up the bios. Does anyone know what I do and how I can fix/do this?
