Having done several non-standard IDE interfaces before, I can say PIO mode for the IDE OpenCore would be straight forward to implement. DMA is always a bit more complicated. I took a quick look thru the OpenCore documentation. It looks like the core would work on the 8xx bus with few modifications. > I have downloaded the lmbench software to determine some benchmarking information.

Sure, download our Journeyman product for 8xx, it includes cross-compilers and 8xx userland. ftp://ftp.mvista.com ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
