It would be possible, but this memory also is disabled after reset. To use it as RAM you must enable graphic controller's SDRAM controller first. And to enable graphic controller's SDRAM controller, you must init its PCI configurations space first, otherwise you can't access its registers.... Using CAR is much easier, as it depends only on CPU features. Juergen -- linuxbios mailing list [email protected] http://www.linuxbios.org/mailman/listinfo/linuxbios
