Did you enable Memory, IO, and Bus Master on the IDE? You need Mem and IO
enabled even if there are no memory regions associated with the device -- I'm
assuming that if I possessed the PCI IDE spec, it would tell me that a PCI IDE
device receives ISA bus cycles or some crazy thing like that.
Sorry I can't explain WHY it needs these -- I
don't know :-). But when I was
programming the bus for my project, I found I needed them.
Any devices which export legacy ISA memory or address regions need
memory and I/O decoding turned on. Since legacy ISA resources aren't
reported in the base address registers, you have to be careful...
