Hi:
I'm trying to configure a box with 6 IDE interfaces
and not getting very far. I followed the instructions
at the top of `ide.c' and patched the kernel correctly,
I think, but I get an oops when the kernel tries to probe
for ide4 and ide5.
My configuration:
Intel motherboard ide0, 1
Promise UltraDMA/33 PCI ide2, 3
Promise UltraDMA/33 PCI ide4, 5
Hopefully the PCI autoconfiguration should have selected
the correct ports and IRQs, so I didn't spend too long
thinking about those.
My question, then: do you have any patches to the latest
versions of the kernels which successfully enable ide4
and ide5, and are you planning on increasing the max
number of interfaces in the standard configuration?
Rich.
