This is only FYI. I have successfully gotten our IDE support to work with
multiple PCI interfaces, and have added Promise support to one of my
experimental copies of the system. One very important note: I was having
a significant number of I/O errors, but was using a nice, long IDE cable.
When I started using the cable included with the Ultra/33 WDAC35100 drive,
the errors went away. The results speak for themselves:
System: Dual PPro/200, running SMP (1 512K CPU, and 1 256K CPU), with
FreeBSD-current as of a week ago + some mods and improvements. The IDE
code is pretty much the same as in -current, with code to support multiple
busmasters. The filesystem is 2K/16K UFS. There are 4 other IDEs sitting
on the MB PIIX3 controller, and 1 IDE (the WDAC5100 drive) on the
Promise Ultra/33 controller. This code is not in -current yet, and it
will likely be a week or so before it is ready to be committed. Note
that the IOZONE being run is modified only to support more complete results.
