USB Bootable Drive to Flash BIOS

How do you make a bootable USB drive so that I can flash the BIOS on the abit IN9 32x Max. It doesn't have support for Exx50 CPUs out of the box, so Flashing the BIOS is the first thing I need to do. I don't have a floppy drive available to use at all. If it comes down to it, I will just go buy one... But I don't want to have to do that. Someone here has got to know! Help!

Thanks

Use this utility from HP... very slick... then put your BIOS files on the drive and go...
