The disk is now connected to the HPT366 controller on the Abit BP6 board (instead of the PIIX4 controller). There are actually a few differences to be seen. The previous bonnie figures for UDMA33 are included for comparison. > 3. Dual Celeron-366, 66 MHz system bus, 256 MB memory, > IBM DPTA-372730 (EIDE), 4.0-CURRENT as of 29.

It is only sequential read that show any marked difference (more than 53000 kB/s). Notice also that two of the runs produced sequential write bandwidth that was only about half of the other runs. I also had one run which made the machine hang solid - couldn't break to DDB or anything. This indicates to me that there may still be bugs in the HPT366 support.
