Recently there was a post from somone who had a Xetec Fasttrack for a couple of years. He said that the driver disabled interupts for an unreasonably long time. Does anyone know if the current driver shipped still does this? I do an awful lot of up/downloading........ Also, the AmigaWhirld article states that the Xetec is a DMA controler. Is this really a new controller or did amiga or did AmigaWhirled screw up again? Eric Edwards: c506634 @ "The 3090. Proof that by applying state of the Inet: umcvmb.missouri.edu art technology to an obsolete architecture, Bitnet: umcvmb.bitnet one can achieve mediocre performance."

The XETEC controler uses what the manufacturer calls DMAx, which they claim produces DMA like speeds without the DMA bus contention when working with hi-res screens. However, I believe that the controler is really NON-DMA and uses really efficient driver software. I own a XETEC FastTrack controller driving a 48 MB 28ms seagate drive. Even with the pathetic Seagate I get throughput of about 400 Kps. The Claims of 750 Kps (Kilobytes per second) can only be realized with a really fast hard disk. I have also added the 4MB fast ram daughter board for $360 from the manufacturer with 80ns simms. I'm running it on a circa 1987 rev 5 A500 and it works great. I've never experienced any waiting while the hard drive is accessed. I've even been able to work on one partition while de-fragmenting/optimizing another. Hope this helps...

I bought the Xetec and put in a Conner cp-340. When I bought the Conner, we tested it out on the sellers Hard Frame. It got 600+k/sec (with no HD noise!) When I got it home though, I was dissappointed to find that the max the Xetec can do for my A500 is a VERY pathetic 150k/sec! I tried everything....but no go. The Conner is weird. It works with the the Miniscribe asyncronous driver AND the Quantum syncronous driver. I bet that the Conner needs it's own syncronious driver to perform it's max.... oh well Phil Dietz -- Subliminal Signature Phil Dietz A M I G A 231b3678@fergvax.unl.edu Univ. of Nebraska
