STATUS:

o The core setup works within limits.
o The scsi layer seems to almost work.
I'm still chasing down the hang bug.
o The block OSM is mostly functional
o LAN OSM works with FDDI and Ethernet cards.

TO DO:

General:
o Provide hidden address space if asked
o Long term message flow control
o PCI IOP's without interrupts are not supported yet
o Push FAIL handling into the core
o DDM control interfaces for module load etc
o Add I2O 2.0 support (Deffered to 2.5 kernel)

Block:
o Multiple major numbers
o Read ahead and cache handling stuff. Talk to Ingo and people
o Power management
o Finish Media changers

SCSI:
o Find the right way to associate drives/luns/busses

Lan:
o Performance tuning
o Test Fibre Channel code

Tape:
o Anyone seen anything implementing this ?
(D.S: Will attempt to do so if spare cycles permit)
