- NOTE: Read these instructions completely before starting. Follow all instructions EXACTLY.
- On some other Windows-based PC, make sure that you have the .BIO file for the BIOS release you wish to install.
- Insert a 32GB or smaller (the smaller the better and the older the better) USB 2.0 flash drive into the PC. Do not use USB 3.0 flash drives (most are not compatible). It is also best if you use a flash drive that has an access LED that you can watch.
- Format this USB flash drive using the Windows Format applet. Select to install the FAT32 file system (NOT vFAT, NOT exFAT; FAT32 only). You must also specify that the Quick Format option be Disabled (unchecked).
- NOTE: If FAT32 is not offered as a choice by the Format applet, your flash drive is too big; use another.
- Copy the .BIO file into the root folder of this USB flash drive. This should be the only .BIO file in the root folder of the USB flash drive.
- Properly eject the USB flash drive. Do not just yank it out. Do this from File Explorer or using the Safely Remove Hardware and Eject Media System Tray applet.
- Power off the Desktop Board system.
- Remove the yellow BIOS Configuration jumper from the board. It will be the only yellow jumper; the rest will usually be black.
- NOTE: Remember the pins that this jumper was plugged onto; you will need this information later.
- Plug the USB flash drive into one of the black USB 2.0 ports on the back panel of the board. Do not use blue or yellow USB 3.0 port. Do not use any front panel USB ports.
- Power on the system.
- The BIOS Recovery process should start automatically. You should see a progress report on your main monitor.
- NOTE: If you do not see a progress report displayed on a monitor, do not power off the system for at least 15 minutes. While it is rare, it is possible for the process to proceed without an onscreen display; you must give it ample time to complete, just in case.
- When the BIOS Recovery process is complete, you will be asked to power off the system. Do so.
- Restore the yellow BIOS Configuration jumper to the pins it was on previously. This should be across pins 1 and 2 of this (three pin) header.
- Remove the USB flash drive from the back panel of the board.
- Power on the board.
- Immediately begin pressing the F2 key, over and over (approx. once per second) until you see the BIOS Setup (or Visual BIOS) screen displayed.
- Verify, using the BIOS version string, that the BIOS installed properly. Stop if it isn't.
- Press the F9 key (followed by the Y key) to reset of the BIOS configuration.
- Press the F10 key (followed by the Y key) to save the BIOS Configuration and exit BIOS Setup.
- Once screen is cleared (goes black), begin pressing the F2 key, over and over, until you see the BIOS Setup screen displayed.
- Make any changes to the BIOS configuration that you desire (for example, disabling NUMLOCK) or that you require (for example, setting Boot Order, enabling UEFI, etc.).
- Press the F10 key (followed by the Y key) to save the BIOS Configuration and exit BIOS Setup.
- Test.
Now, since you have to install a number of BIOS releases, here is an overall process to follow:
- Use this above process to get BIOS 48 installed.
- Delete the .BIO file from the USB flash disk.
- Starting from Step 6, use the above process to install BIOS 99.
- Delete the .BIO file from the USB flash disk.
- Starting from Step 6, use the above process to install BIOS 120.
Good luck. If you cannot get the BIOS to recognise your USB flash disk, get a smaller/older one.
Do not use iFlash or EBU executables. Use only the BIOS Recovery process to install these old BIOS.
