- Failed motherboard with F9 POST code
- Latest BIOS release for your motherboard
- A FreeDOS / MS-DOS formatted USB drive (see our FreeDOS USB creation guide here)
- If you do not already have a copy of the latest BIOS, head to Supermicro’s main web site: http://www.supermicro.com/index_home.cfm.
- If you have a copy of the latest BIOS already, skip to step 7.
- Enter your motherboard model number in the Search field to the upper right of the page. This model number should be listed in DMI and FRU info for your system.
- Select one of the top results from the next page to enter the motherboard support page.
- This will take you to the motherboard support web page. On this page, click on “Update Your BIOS” under Links & Resources.
- Click on the hyperlink for the .zip file on the next page, and accept the EULA to start the download.
- Once you have a copy of the latest BIOS, extract the .zip file and locate the BIOS binary file. Motherboard BIOS files are named by their motherboard model and release number, and will have a number for the file exension.
- Rename the file to “SUPER.ROM”. Be sure to replace the file extension, otherwise the file will not work.
- Copy the SUPER.ROM file to the root of the FreeDOS/MS-DOS USB drive.
- Make sure the server is completely powered down. Plug in the USB drive into a USB port on the motherboard, then power on the server.
- The BIOS recovery should automatically start. If it fails to start automatically, you may need to manually force the recovery with a hotkey combination. While the system is powered off, press and hold down the <CTRL> and <HOME> keys simultaneously, then press the power button while holding down the keys. Watch for I/O on your USB drive: As soon as the drive activity light flashes you can release the keys.
