Questions on ScsiMiniport driver for native mode

Hi all~

I have some questions on ScsiMiniport driver for native mode.
My PCI IDE card has 2 channels with 4 access ranges. What should
I reserve the necessary resources for this one under only one IRQ ?
My though is “allocate only one device extension and two seperate
PRD table for the DMA operation”. Any other else I forget ?

Any comments are very welcome!!

Merry Christmas!!
