Has anyone been able to > use it, let's say with a hard disk? Any tips regarding this problem? 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. -- Dan ** Sent via the linuxppc-embedded mail list.
