Sure. IDE is not supported on that machine. Although the hardware is
available, this hardware is hidden from the OS. This machine was
intended to use SCSI only. Hence no OFW support for IDE. You have to
add quirks to make IDE work.

IIRC I had no PCI memory problem. I think once I got an ex(4) to emit
packets because it uses PCI memory only. PCI DMA was the problem.

A SCSI bus needs to be terminated at booth ends of the cable. Without
cable or with a short cable a single terminator should work. Check if
there is a terminator on the mainboard that can be en-/disabled by a
jumper.
