[Qemu-devel] Re: [RFC] linuxboot Option ROM for Linux kernel booting

["Nguyen Anh Quynh" <aquynh@gmail.com>]

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
