Copy the BIOS update executable onto the newly formatted floppy drive. Reboot your computer and boot to the floppy drive. Run the BIOS update executable. It should reflash the BIOS automatically, with very little interaction required from the user.
Can I reinstall the same BIOS?
Yes, that’s fine. However removing the CMOS battery for a few minutes with power removed will also reset the BIOS.
Can I flash BIOS twice?
Not entirely. Think of it more like an update that is not dependent on a previous version. In order to completely erase a BIOS chip you would need to use a specialized tool created by the BIOS manufacturer.
