This is what you get:

RD1 BIOS Savior	BIOS Chip Extraction Tool
BIOS Selection Switch and Cable	Slot Cover for the BIOS Selection Switch
English and Japanese Manual	RD1 Sticker for your case

How is the RD1 constructed?

A Flash Chip
B Electronic Switch
C Connector for selection switch

So how does it work?

Installation is straightforward:

1. Locate the BIOS Chip	2. Remove the BIOS Chip using the extraction tool
3. Insert the RD1	4. Attach the cable
5. Insert the BIOS Chip on top of the RD1	6. Ready!

With the RD1 installed, you can now choose the active BIOS chip by using the switch.

After installing the RD1 you might want to back up your BIOS first. In order to do so, use your flash utility to save the mainboard BIOS to a file, then switch to the RD1 and flash this image into it.

If your mainboard BIOS chip does no longer work, switch to the RD1 and boot from it. Switch back to your mainboard BIOS and repair it by re-flashing.

Also, if some or other mainboard has BIOS troubles, simply take it's BIOS and place it onto the RD1. Boot from RD1, then switch to the faulty chip and flash it. Think of how your friends are grateful if you help them to recover from a bad flash ...
