BIOS upgrade for Asus 1005HA Netbook in Windows 7

The BIOS in the ASUS 1005HA netbook was shipped without support for ACPI in Windows 7. All the blue function keys on the netbook rely on the ACPI layer to work, therefore, I decided to upgrade the BIOS to the latest in order to run Windows 7.

There's only one problem -- the BIOS flash program, called ASUS updater, downloaded from the ASUS web site under 1005HA support, relies on ACPI to work :)

To get around the problem, you need a BIO flasher that can work without ACPI support. I searched the ASUS support site for the motherboard model and found this one:BIOS flash utility 6.10.02 I used it to flash the board with the latest ROM and everything works like a charm in Windows 7.

I also read some posts on the web that people has been downgrading the BIOS in order to get the flash utility to work, then upgrading the BIOS again. That's just too much busy work :)
