No. In the boot process, the /boot/loader.conf file gets loaded, the kernel file gets loaded and then you boot. If you break into that process, you can change settings. This also works for hints that are read in from /boot/device.hints (which comes in handy if you've set the wrong interrupts, or have a device driver that panics the system that's automatically loaded, etc). : > I think that I understand why this didn't work, but don't understand : > what would. Maybe leaving things alone is the right idea. Turning on : > PCI interrupts vs ISA interrupts is done in register 3E.. : : The existing init_routing = 0 seems to work fine. :) :) :) :) Right. The hw.pcic.init_routing has nothing to do with clearing the intr enable bit (it enables ISA interrupt routing via ExCA registers for function interrupts).
