SubjectRe: Any experience with Promise PDC20376 and SATA RAID?

There is no GPL/LGPL support for the promise 20376 Fastrak 133
controller on Linux at the moment. There is a binary module from
Promise, but only on 2.4.18 i believe.

I think someone is working on reverse engineering the code for
stock kernel inclusion.

I've got the same controller on my board, but no use for it
since i only have 2 disks on the machine which fit nicely on the
2 onboard IDE controllers in my A7V8X motherboard - though it'd
be nice to be able to buy and support ATA150 drive speeds.
