I now have two Intel ISP1100s humming away in a rack in Fulham. They're

1) They won't power off with a shutdown -p. Is this anything to do with
the following comment in dmesg:

apm0 at mainbus0: Power Management spec V1.1 (BIOS mgmt disabled)
APM power mgmt engage (device 1)
: power management disabled (0x10f)
apm0: A/C state: on
apm0: battery charge state: no battery


Intel 82371AB Power Management Controller (PIIX4) (miscellaneous bridge,
n 0x02) at pci0 dev 7 function 3 not configured

2) How do I force the boot loader to not be confused by the BIOS claiming
the serial port it's using for redirection is nonexistent? It's not a
problem that I'm using bot serial ports (one for the BIOS, one for NetBSD)
right now, but it'd be nice to be more gadget-efficient.

3) I get a lot of "stray interrupt 7". Any ideas as to what might be
making such interrupts? The ISP1100 lacks a parallel port...

4) I've got the front panel LEDs working nicely. See for a userland
driver. Who thinks this should be in the kernel? Votes? It'd be nice to
tie it into the system state a bit better - perhaps init could control the
LEDs, using the power/fault indicators to show if the machine's booting,
halted, running, or in single user mode... leaving the two other LEDs for
userland stuff.
