Just booted it up and it runs wonderfully :) So, the IOP firmware for the E series has not only been found, but confirmed to work! It was so neat to type "HEL-A000..." on a terminal this morning. The dual E's are noticeably faster than my dual 2100 Access system, but not as much faster as I would have expected. Odd, since the processors are significantly faster, and using the high performance memory option. The basement doesn't heat up quite as much running on two E's as opposed to two 2100A/S. Also, I seem to be able to run it indefinitely without tripping a circuit breaker. Nifty! I ran in to lots of cpu problems this morning, and had to go through every one of my 21MX-E spare cpu's to get a working combination. Yikes - makes me wish I hadn't given away all my E's. At some point in the future I should probably try the M series firmware board, just to be sure that works as well. I also wound up having to scavenge some parts from my 2100 Access system to get the MXE Access system up. Bummer! Hopefully some trades will produce the necessary stuff to have both operational. Yup, I'm pondering some RJE setup between the two :) Oh, except I apparently only have one set of processor interconnect cables, thought I had two :\ Making up THOSE cables will suck. Anyways... just wanted to let folks know that the E series IOP firmware is definitely a go. The biggest problem I had was trying to figure out how to set up the FAB board. I'd really have preferred to go the FEM route, but Access is so hard-coded in the system processor side of things. Regards, Jay West
