There are at least three easy and inexpensive ways people add ATA/IDE
to the 8xx processors for embedded systems:
Connect to PCMCIA interface
Use a simple CPLD between the processor bus and disk
Program one of the UPMs to generate timing and then
externally buffer the signals

It is a more difficult solution on the 850 because of the PCI bridge
(fewer
physical address lines). It is also the most expensive in money, board
space and software.
