Confirm the system you are using

In some motherboard it is necessary to adjust the jumper on the motherboard before updating the BIOS. After installing RD1, writing BIOS into the ROM of RD1 or into the original ROM will all be affected by jumper setup. Therefore, read the operation manual of motherboard first and confirm the adjustment method of jumper.

1. Selection of ROM

Due to different production batch, there are two versions of selection switch metal (at one end of switch cable) in RD1 product, shown separately in the following drawings. User of Type1 may use the attached sticker as shown in Type 2 below. The user may use it directly by sticking the sticker on the metal plate to facilitate defining.
For example, definition "1" and ORG represents original ROM, "2" and "RD1" represent backup ROM of RD1.
The following explanations were executed according to these definitions, that is "ORG" and "RD1", i.e. Type 2.

First operation
When operating for the first time after installation, it is necessary to set the switch to "ORG" position then start the system.


2. Prepare System disk with Flash Utility

You need to make a bootable disk with BIOS Flash utility. You should be able to find how to make and where to get the Flash utility from your system/motherboard vendor web site. You have to get the flash utility from your system/motherboard vendor web site.

Here is the simple step.

To create the system disk, prepare blank disk and use:

 format a: /s

at the DOS prompt (it doesn't matter under Windows environment) copy Flash utility to the boot disk. The Flash utility name varies with each vendor but awdflash.exe, amiflash.exe, aflash.exe, aoflash.exe flashxxx.exe are popular names. Do not copy extra files other than create automaticaly by above method, Flash utility and update BIOS data.

3. Backup method of BIOS
a. Set RD1 switch position to "ORG" then start the system and execute BIOS Flash Utility.

b. Execute BIOS backup (Save) function to save BIOS data into the file.

c. Keep at System On state. Move RD1 switch to "RD1" position, then re-execute BIOS Flash utility.

d. Execute BIOS Data Program in order to copy the BIOS data that was saved in Step b into RD1 ROM.

e. Now RD1 ROM is loaded with BIOS data. To verify that RD1 ROM is loaded properly, keep the switch on the metal plate to "RD1" position then restart the system. If the system does not start, this means loading failure. Repeat the entire procedure. Some BIOS or utilities will not work properly until this procedure is repeated twice.

f. After confirming that backed up BIOS works properly, change the switch to "ORG" and operate the system as usual.

If messages like "ROM size mismatch" or "Unsupported ROM type" appear on Flash utility while writing BIOS data, this means ROM capacity of the two chips do not match or the flash utility does not support the BIOS ROM of RD1. If the ROM capacity of motherboard and RD1 is the same, then it is necessary to use the updated version of BIOS Flash utility.

4. Updating Method of BIOS
Set RD1 switch to "ORG" position. Use BIOS Flash utility to write new BIOS data.
5. During BIOS update failure or invaded with virus
Set RD1switch4
to ”RD1” then restart the system. Since RD1 backup ROM is loaded with BIOS, the system will restart easily.
Actually RD1 is not necessarily used as backup. So RD1 can be set for general use and original ROM as backup.
The internal circuit of RD1and original ROM does not access each other. The selected backup ROM is an independent individual and will not enter the system nor does it have any access on the data through the system circuit. Therefore, the user can update the BIOS safely. Once it the data of ROM that is for general use is damaged, set the switch to ”RD1” and restart the system, then set the switch to "ORG" to execute Step 3 and load the correct BIOS data into the ROM.
If the BIOS had damaged by suspicious of Virus, you must act very carefully. Following actions are recommended.
  • Remove the Hard disk cable.
  • Remove floppy disk, if it is in the drive.
  • Change the RD1 switch to "RD1" then start system.
  • Enter BIOS setting then change the boot setting to "boot from Floppy" then turn off the system.
  • Prepare absolutely clean system floppy disk with Virus clean utility in it.
  • Connect Hard disk cable. Insert the clean system disk in floppy drive.
  • Boot the system then execute Virus clean utility.

By above operation, your backed up BIOS on RD1 is minimized from damage.
