Read slaymate's post on the first page. It's really simple. You just download the firmware, burn the .iso file to a cd using a free program like Active ISO I think it's called. Then go into bios and set your cd drive as the first boot and follow the installation from there. There's nothing complicated about it.
Can I use the new computer that I am building without an os installed yet or should I use a computer I already have and hook it up to a port in it?
Can I do it in an XP computer?
