Booting from a U3 USB Flash Drive

Hi, I'm new to the whole OS development stuff and I managed to create a simple kernel in assembly and C. I have compiled it and have boot.bin and system.bin. Is there any way that I can boot my operating system using my U3 bootable flash drive?
Any resources and tutorials you find would help!
thanks!

Am I right to assume your flash drive is USB?
Most new systems offer a multitude of USB booting capabilities.. Pretty sure most just emulate a hardrive.
I don't have much information about this.. sorry..

By the way, anyone know how to use grub on an msdos partition? The installation goes all weird inside qemu.

Thanks guys, it should work
Edit: with grub, how do I load the kernel and the boot file?

(
Grub would normally replace your "boot" file..
Unless it's a second stage..)
But with grub your kernel should support Multiboot..

You may also use a separate boot loader (
boot) and chain-load it with grub.. but that sorta negates the entire thing..
