There are a limited number of system BIOS calls that need to be implemented. It is a fairly small number. wakeup.S could supply implementations for these and patch them into the right interrupt vectors while the VBIOS is being run. There is no requirement that VBIOS run the actual system BIOS, it only has to think that it is running on the system BIOS. This is the same scheme used for running the ROMs in user space. -- Jon Smirl jonsmirl-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org ------------------------------------------------------- This SF.Net email is sponsored by: IntelliVIEW -- Interactive Reporting Tool for open source databases.
