Booting from a U3 USB Flash Drive

Post by dcboy »

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.

(Grub would normally replace your "boot" file..:roll: Unless it's a second stage..)

But with grub your kernel should support Multiboot..

http://www.gnu.org/software/grub/manual/multiboot/

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