Great!
but there still some problems which should be considered
- how to make usbrom only respond to requests which used for usb
not hard
disk. ( in my eyes, diff these requests by drive number?) 2) how do assign the drive number for usb disk? just followed by 80?
anyone
can give me an details about that?
This is covered in the bios boot specification (bbs) document.
