Peter Anvin" Hi, I am thinking about comibing this ROM with the extboot. Both two ROM are about "booting", so I think that is reasonable. So we will have only 1 ROM that supports both external boot and Linux boot. Is that desirable or not? Thanks, Quynh On 4/21/08, Nguyen Anh Quynh wrote: > Hmm, the last patch includes a binary.
