Well......Cort had it working once, I tend to break and fix it at
various times. I think right now it is broken......
The IDE has assumed knowledge of PC-style addresses and behavior. To
use things like ATA Flash cards in the PCMCIA of the 8xx, I break the
generic IDE interface. On the 8xx, it is also sensitive to the interrupt
controller. Cort and I are always going back and forth about how to
use the internal interrupt controller in combination with the external
8259. I want things that are more generic to other 8xx boards, and to
get IDE to work you have to make assumptions unique to the MBX.
I understand it would be nice to have the IDE working on the MBX, but
all of the products I have worked with use ATA flash....nothing has
ever used an IDE drive through a PCI/AT bus adapter. This is why code
I tend to check in will allow PCMCIA ATA Flash and not the more complex
external IDE.....it represents products in the field.
