Flash BIOS from USB?

This is a ridiculous question.

New PC that I'm having issues with RAID setup so I'd like to update
bios BUT the file is > 2mb. I really don't want to go on a hunt for
2.8mb floppies (nor do I want to be seen purchasing them). Any way to
make the file available to bios flash? USB?

thanks.

Nevermind. I reformatted the flash usb stick and it was instantly
recognized. Not sure of the issue before, but it worked.
