You need to setup ITR and DTR to map the first 256Mb of memory. Also as soon as possible you need to call map_pal_code() to pin down the region which holds the PAL (preferably *before* you try calling any PAL functions. > > BTW: I moved scanning the MADT to a place where it now happens to > be called only when SMP is defined. This is bogus. I probably > broke non SMP configs :-/ I guess it needs its own SYSINIT to make it run just before the MP initialisation code. -- Doug Rabson Mail: dfr@nlsystems.com Phone: +44 20 8348 6160 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe cvs-all" in the body of the message
