Over the years I have had to update many BIOS chips on many systems, However coming mostly from a Microsoft background in computing I had normally done most of my BIOS updates via a DOS boot disk, or a DOS or Windows application. So when It came to updating the BIOS on the eee 701 Xandros auto update did all the work for me and I didn't have to worry. I have now installed eeeUbuntu 2.0 (By far the best distro for the eee I have tested) and I had no idea how to do a BIOS update.

I need not of worried, here is a small how-to, on updating the eee BIOS.

1) Goto http://support.asus.com/download/download.aspx?SLanguage=en-us
Select EEE family in the product, then your model in the series, Now find the BIOS ROM file you require.

2) Once you have downloaded the new BIOS ROM unzip the file and rename the ".ROM" file
to (For the eee 4g and all over 701 models) to "701.ROM" if you have a 901 then of course rename to "901.ROM" and so on.

3) Copy the newly rename ".ROM" file to a newly formatted USB stick (None the formatting has to be FAT or FAT16 -
(FAT32 and NTFS WILL NOT WORK)

4) Now insert the USB stick into the EEE and power on, during BIOS check screen press "ALT-F2"
This will then enter into a BIOS update via USB screen, follow a few on screen instructions and your BIOS will be updated in no time at all.

5) Enjoy your new BIOS.
The 1101 for the eee 701, has some great fixes, one I noticed right away was much better CPU scaling, the main reason Installed this BIOS was to fix a bug I had while booting the EEE with an SD card installed, it would hang the system with any distro based on ibex (Cruncheee, and eeeBuntu 2.0 for example) All fixed now and running like a dream, oh and the battery life is about 20% long with this BIOS.
