I'm trying to update/flash the BIOS on my HP a1640n (Asus P5BW-LA motherboard) running Windows XP Pro SP3 (32-bit) from 3.08 to 3.17. I found and downloaded the "new" BIOS (in the form of sp35153.exe) and tried to run it multiple times. However, every time I ran it, I got an error message saying that I wasn't logged in as an Administrator (even though I was) along with displaying the number 9999 (which I'm assuming is the error code).
Is there something I'm doing wrong? Is there a BIOS flashing program that I should be using instead? I tried installing a 2.4x version of Asus Winflash, but it wouldn't install because it was intended for netbooks according to the installer. And AFAIK Asus' EZFlash can only be used if your motherboard came with it.
