Please always include your question in the body of the message on Usenet.
If the PC's BIOS supports it (and I assume we're talking about a traditional PC, and a traditional - aka non-EFI - BIOS here), then the USB disk (which might, after all be a real rotating disk too) will be accessible through the usual Int 13h functions. And it boots the same way.

That's about the same answer I gave to this question, in another group.

disk?
eIt's not very consistent, unfortunately, but if you have the emulation turned on in your BIOS, it's most commonly a hard disk. In some BIOS's it's configurable - you can set the BIOS to emulate either a floppy or HDD. If it's the boot device, it'll be 0x00 or 0x80. And remember there can be more than one.
