New Description
The Chihiro uses a earlier version of the Xbox motherboard based on the Xbox development kit motherboards, utilizing a earlier version of the Nvidia chipset (MCPX X2) and a "Arcade" Kernel. As with other debug motherboards, it features 128MB of RAM, twice the amount found in a retail Xbox.
Typicaly a Chihiro came in two versions, earlier in the release of the chihiro it was using a Xbox motherboard with the old style powerconnector and connected to the baseboard was a Type 1 DIMM board similiar to a Naomi.
A newer version, probebly using the newer ATX powersupply connector is a Type 3 Chihiro with a media board integrated (with ram varieing for 512mb to 1gig for gameloading. There are no known Type2 models.
The Xbox gameboards are found in 4(3?) versions. In Type 1 Chihiros you might find a motherboard with 3 CPU caps or 4, and a old singleline powersupply connector or a ATX modern powersupply connector.
On both the type 1 and 3 the GDRom can be connected to the Mediaboard over special SCSI like cables. there are adapters availeble to load games from CFcards instead for faster loading. for all games PIC key like adapters are required but hacked keys are sold to allow any game. (I a editor of this page, arent sure if all names or parts are correct, but please help make this better if you know more)

Not all names for parts are the same everywhere with sellers and collectors but generaly the following names are used:
Xboxboard or gameboard(?)
baseboard the one with the lpc connector and gamecontroller IC (it contains the calibration in eeprom)
Mediaboard (this is diferent from type 1 or 3, type 1 has connectors for a Naomi netdim)
A type 3 mediaboard also(could?) have a network board, wich allows loading certain games over network or network play.
Filter Board, this is where the audio connects and gets it power from a PSU (standard naomi connectors)
On both the type 1 and 3 the GDRom can be connected to the Mediaboard over special SCSI like cables. there are adapters availeble to load games from CFcards instead for faster loading. for all games PIC key like adapters are required but hacked keys are sold to allow any game.
