Hey there davidstark
Firstly could you tell us what processor you are using in this board, is it the AMD Athlon 64 or other?
Secondly, your question 1 and 3 are techincally the same thing, awdflash is used to flash/update the BIOS.
- what is the main reason for you wanting flash the bios, is it souly because you have seen an update on the Asus website or are you wanting to run a newer processor which aren't currently supported by the current BIOS version?
Thirdly, chipset drivers, personally I wouldn't use the Beta version for something like chipset drivers, mainly because Beta means it is a test, so they haven't gotten rid of all the bugs yet. If there are problems it will crash windows quite often in theory.
I would use v 6.34, the answer to my first question will help determine whether you need to download the 64 bit or 32 bit version.
