BIOS Savior is a device able to deliver total protection to the motherboard's BIOS against incorrect upgrades or viruses like CIH. Thanks to the built in FlashROM, after installing the RD1, you will have two BIOS chips and with the small included switch you will have the ability to chose which BIOS to use when booting your PC. Since the two chips are separate and only one can be active at any time, if something goes wrong with the first BIOS you can always reboot your PC using the other BIOS and then restore the damaged one.
