I haven't been following this thread closely. So, pardon me if I'm going over old ground. My ASUS A7V333 mobo has a similar IDE controller... 00:11.1 IDE interface: VIA Technologies, Inc. Bus Master IDE (rev 06) (prog-if 8a [Master SecP PriP]) Subsystem: Asustek Computer, Inc.: Unknown device 808c Flags: bus master, medium devsel, latency 32 I/O ports at a000 [size=16] Capabilities: [c0] Power Management version 2 It's works well at fairly low latencies. But, to get that working, I had to upgrade my kernel to 2.4.19. The 2.4.18 (and earlier) IDE device driver unable to do DMA with this chip. Fixing that made a dramatic improvement in disk performance. Have you already gone through all the hdparms rigamarole? -- Jack O'Quin Austin, Texas, USA
