RAM. Actually kernel code :( There no way to access ISA mem on most Macs. >We don't need any more kernel assistance, just to fix the syscall to >return an error for the AGP bus of Uni-N if we can't do any io there. We can do _IO_, not ISA mem. Some cards require IOs accesses to some VGA registers so we need the syscall to work. IOs are indeed possible on all the UniNorth busses. >Since 4.1 went out broken we can't do much now, the best solution will >be to disable the ioctl (since we don't get the right base anyway) How ? If you get base for bus 0, you'll get the AGP which is what you are looking for in this case. Ben.
