Thanks for clarifying that.
Questions:
How do _you_ determine the appropriate append strings for the Promise
channels from cat /proc/pci/?
How do _you_ determine the appropriate append strings for the mobo
IDE channels?
Once I have this information, I can experiment in your tracks.

Huh? I do want it controlling IDE2 & IDE3. This happens
automatically with many kernels, but not the one used in the 7.2
installer (limited to IDE0 & IDE1).

I have not experienced this (yet?). My new mobo and drives accept
DMA operation - to great advantage. You may possibly be striking a
very common defect in mobos.
