Oh yeah, it works.  Has since I put it in.  It's just one of those
boards that implements the Extended IDE, capable of something like 14
MB/sec with the drivers and a fast EIDE drive.  Since I have a lower
speed drive daisy chained on with it, I could only acheive something
like 5 MB/sec or a bit less under DOS/Win.  This thing uses a chipset
made by Promise themselves which they  license to other OEMs.  I'm not
sure if it is CMD640 compatible (I doubt it) as the manual doesn't say
anything about this and they supply their own drivers.

I was just curious if anyone knew of any support that might have been
added in the 2.1.xxx kernel series for the Promise chips.  A bit more
throughput than the current 1.5 MB/sec I'm probably getting now would be
nice.

Or, see if I can cause it to crash spectacularly!

Thanks, Happy Thanskgiving to all!
