+Current Release

+
+
+Previous Stable Release (2.4.18ac3)
+	AMI MegaRAID[0]		FAIL
+	DPT Smartraid		------------ Use dpt_i2o module ------------
+	Intel SCU RAID		FAIL[2]	???	N/A	???	FAIL[2]
+	Promise Supertrak100	YES[3]	YES[3]	N/A	YES[3]	N/A

+[0] In I2O mode. For normal mode use the megaraid driver
+[1] Initialisation oddities and scsi failure. Use dpt_i2o module instead.
+[2] Card hangs under certain load patterns.
+[3] The driver works correctly. Certain values are misreported by this
+card but the results are only cosmetic. Firmware updates are required for some
+very early cards. Set the card into I2O not 'Linux' mode.
+[4] HTML configuration mode not available.
+
+Requirements
+------------
+
+I2O 1.5 compliant hardware
+PCI bus interrupt driven I2O devices
+Devices in classes Block, Lan or SCSI.
+32bit I2O messages supported
+
+Limitations
+-----------
+64bit message formats are not supported (64bit I2O is basically a whole 
+		different driver variant)
+I2O Tape class is not supported (no known devices using this..)
+Currently only 32bit x86 platforms are supported.

-STATUS:
+Promise
+	Providing a Supertrak 100 board and support info
 
-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.
+DPT (now Adaptec)
+	Providing a DPT smartraid I2O card (use dpt_i2o for this
+	board however)
 
-TO DO:
 
 General:
-o	Provide hidden address space if asked
-o	Long term message flow control
+o	Finish 64bit and big endian cleanup
+o	Switch to new PCI mapping layer throughout
+o	Hotswap of controllers
 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	Multiple major numbers (problem goes away in 2.5)
 o	Power management
-o	Finish Media changers
 
 SCSI:
-o	Find the right way to associate drives/luns/busses
 
 Lan:	
 o	Performance tuning
