Re: Can't get into the BIOS
Since it's giving you a BIOS ROM checksum error, you may be able to reflash the BIOS and get your system up and running again. You'll need to look up your motherboard model number (or PC model number if this is a pre-build computer like a Dell or HP, etc) and then download the BIOS update software from the manufacturer's website. There will be instructions on how the flash the BIOS there. The one thing that concerns me is the floppy drive error as a lot of BIOS updates run from a bootable floppy. There are ways around it such as booting into DOS or Windows from a USB flash drive, but those ways can be complicated if you've never done it before.
But I'm trying, Ringo. I'm trying real hard... to be the Shepherd.
