I recently started thinking about upgrading the stock Solid State Drive with a faster and higher capacity model. It runs fairly fast already since I use light-weight applications, but extra speed is always a plus.
The prerequisite on the manufacturer's website for the faster drive was that the Eee PC needed to have a newer BIOS installed. It did not surprise me to discover that my version was so old that it wasn't even listed on ASUS' download page anymore.
I figured that even if I don't ever get a new SSD, at least I'll have a newer BIOS with all the latest fixes and after doing some quick reading I discovered that upgrading the BIOS was pretty straightforward.
- Download the latest BIOS file from ASUS. (version 1102 from 2009/06/16 as of this writing)
- Format a USB flash drive to FAT16.
- Extract the BIOS ROM from the archive, rename it to 900A.ROM, and copy it to your flash drive.
- Place the USB flash drive into the left USB port.
- Plug your AC adapter into the system and reboot.
- Hold down ALT+F2 at POST to launch the built-in BIOS updater.
- Always remember: Do NOT turn off the system until it finishes.
I was forced to use an SD card with a USB card reader because for some reason my 900A could not detect the BIOS when it was on a normal flash drive.
