I call this "FRAID" and it is not hardware RAID (it
adds *0* hardware).
Any drivers will be proprietary and not open

contain RAID code licensed from a 3rd party that is
not GPL (and
never will be, because it is the core IP of that

lifeblood of their business).
Be very 'FRAID. 8-) If it was me, I'd figure out how to get the drives recognized as plain old ATA drives and then use the software RAID striping native to Linux rather than depend on the promise card to do anything other than act as an ATA controller. I think the likelihood of roaching the volume while depending on the promise software RAID bandaid is probably rather high for no performance payoff whatsoever.

My first attempt at RAID...
Tried a different distribution with the latest kernel, and indeed the PTA drives on the Promise controller were recognized but they were recognized as two separate drives while the controller was in RAID mode (rather than IDE mode).
Are you saying that even if the drives are recognized, I will not be able to implement RAID in hardware mode?
Any other options installing CenOS 4 on unsupported hd controller besides:
a. install CentOS 4 while drive in recognized hd controller
b. get new kernel
c. compile/install new kernel (without pulling my hair out)
d. move drives to unsupported hd controller
e. set controller to IDE mode
f. boot using new kernel (while praying)
g. do software RAID ---------------------------------
