Updating The Asus Eee PC’s BIOS

To update the Eee PC’s BIOS is a pretty simple affair with a few catches:

  1. Download the latest BIOS from Asus’ Web site.
  2. Extract the BIOS ROM file.

  3. Rename the file to 1000HE.ROM
  4. Make sure the Eee PC A/C adapter is plugged in.
  5. Copy the 1000HE.ROM file to the root of a FAT32 USB flash drive.
  6. Power down the Eee PC.
  7. Power up the Eee PC.
  8. Press ALT + F2 key combination at the BIOS/Splash screen.
  9. The built-in flash utility will pick up the 1000HE.ROM file and flash it.
  10. Once finished, power down the Eee PC.
  11. Pull the USB flash drive.
  12. Power the unit up.
  13. Press F2 to enter setup (may need F1 after that).
  14. Verify that the BIOS version is the same as downloaded.

We are flashing the 1000HE because the newer BIOS firmware has added support for Windows 7 features.

Any way for a non-Windows user who has installed this to revert to 1002?

Download the BIOS version you want and follow the blog post instructions to put it on a USB stick and flash the BIOS.

The keystrokes to update the BIOS are OS agnostic. Your USB flash drive does need to be FAT or FAT32 formatted though.

Yeah, I tried that... since that's how I updated to 1104. It says gives me an error saying the 1002 bios is too old. There is apparently an Asus Windows utility that has a checkbox that allows you to install old bios... but I don't have Windows.
