I don't believe that the SDK documents the inner working of the OG's power
management hardware - on the other hand, the power driver (which is for
example contained in the SDK) is only about 5k in size, so having look at
how it does things should not be too difficult. My GeoDump tool should be
quite helpful for this purpose... ;-)
In addition, the SDK even comes with sample code for Power Management
drivers. Funny enough, this is one of the few driver types whose interface
*is* documented, while other important types like video, printer or
import/export aren't.
The ultimate source for the OmniGo's hardware is probably the VG230 data
manual (this is the PC-on-a-chip module around which the OG's design is
centered), which is available from Vadem or one of their resellers. This
book gives a good overview on the structure and limits of the OG's hardware
and generally helps in understanding BIOS and driver operations.
