I thought I'd seen a doc about this, but I can't find it now :(
Anyway, to set sio parameters the following is what you need:
To disable a port:
di sio<n>
To enable a port:
en sio<n>
To set the IRQ:
irq sio<n> <irq>
To set the flags:
flags sio<n> <flags>
<flags> is a hex number of the form 0x04
BTW, I thought the filename was /boot/boot.conf. I still use my old
(2.2) /kernel.config by having the following in /boot/loader.rc:
load -t userconfig_script /kernel.config
