Promise will be shipping two ATA/100 raid controllers, one samiliar to the 
Fasttrack66, another one will probably have a i960 CPU and 4 IDE 
channels/conectors. If someone is interested to write support I will try to get 
some controllers and information from Promise although they seem to be a 
little bit sensible about the internals of their products (their linux driver should 
be neither open source nor available as source). I do not know if it is worth 
the work, as by next year Serial ATA should be available. 

I was interested if someone has compared the IDE Raid controllers to 
software raid, some time ago there was a database test (Informix and Oracle I 
think) run on SCSI raidcontroller systems and softwareraid under Linux, these 
tests indicated that the softwareraid was almost on par with the SCSI Raid
