I was looking for a way to say 'controller wd0 at pci?' but this leaves two unresolved in linking the kernel. I can set flags to turn on 32-bit access and PIO mode 4 which really speeds up disk access and yet even though the kernel reports the IDE adapter on the PCI bus it does not assign a drver to it. I think in my case its just that I don't have the right syntax in the kernel config. I someone who understands how to do this, there's two people for sure that would appreciate it. -- Duane Eddingfield Powered by FreeBSD - Real Unix for free!
