Frankly, you buy one if you can't figure it out on your own... It's more of a service charge for the help.
All I've ever needed to know is the make/model of the machine or the motherboard or both.
Remember that some older boards will not have such BIOS updates and we'll see more pleas like yours since many BIOS don't do over 120GB drives.

I wish to upgrage my BIOS so I can install a 40G hard disk. I thought these upgrades were available for free but if so they are very hard to find. Can anyone suggest where I might look for an Award BIOS?
I can buy one for US$24.95. Is that the usual rate?
