This would be a bug, but it isn't quite true. If you look at x86_cpu_reset() you will note that it sets the code segment base to 0xffff0000, not 0xf0000 as one could expect from the above. This is also true of a physical x86. As such, the *real* reset vector is at 0xfffffff0 as opposed to the SeaBIOS vector at 0xffff0 -- this is a backwards compatibility vector which typically just issues a real reset. Now, if Qemu doesn't handle the distinction here correctly, that is a bug. -hpa _______________________________________________ SeaBIOS mailing list SeaBIOS@seabios.org http://www.seabios.org/mailman/listinfo/seabios
