Two pictures posted:

Full USB HID support is built as modular. I don't seem to be able to
change it to built in. make menuconfig is only giving me modular or
not set.  (Kernel config USB info this is set is at the end)

lspci says the controller is an Apple controller and the driver is
'macio' which seems sensible. I see it in the boot screen I think.
That driver is built in, but the PATA_MACIO driver is not:

(chroot) livecd linux # cat .config | grep MACIO
# CONFIG_PATA_MACIO is not set
CONFIG_ADB_MACIO=3Dy
(chroot) livecd linux #

Maybe I've mistakenly left the right disk driver out of the kernel
thinking the hardware was SATA based? Does the PATA_MACIO option need
to be set for the Mac Mini? I don't understand how this kernel config
would have ever worked befor unless I'm confusing where it came from.

Does the append=3D"init=3D/bin/bash" command allow the kernel to load
drivers or do I need to build USBHID into the kernel to get the
keyboard to work at this level of boot?

Thanks,
Mark
