Then both would be run. If one were to put two real VGA ROMs in "vgaroms/", then both roms would be run, both would try to map hardware registers to 0xa0000-0xc0000, and things would break. However, the sgabios isn't a "real" vga rom - it doesn't try to map 0xa0000. Instead, sgabios is just a blob of code that we'd like to run early so that it can hook int10. The "vgaroms/" capability was added specifically to allow sgabios to run early in the boot. http://www.coreboot.org/pipermail/coreboot/2009-May/048678.html -Kevin _______________________________________________ SeaBIOS mailing list [email protected] http://www.seabios.org/mailman/listinfo/seabios
