The Omnigo BIOS supports standard APM calls (just like your PC or
Notebook). Marcus Groeber has supplied me with an assembly dump of the
GEOS power management driver and I've been able to piece together a few
things (like how to shut down the serial port, PCMCIA port, ect). However,
if you just want to shutdown the Omnigo you can simply call the proper APM
interrupt function.

Also, it should be noted that the power drain in DOS is double (or more)
of that in GEOS. This is because DOS does no power management at all.
