Looking at the linux source closer for the hpt driver, I'm thinking it's proprietary. There are several pre-compiled object files that appear to contain the driver code for the various RAID related functions. That also suggests the controller is a fakeraid controller, a HPT trademark, especially given the price point locally. -- Drew "Nothing in life is to be feared.
