HP 9000 735 NeXTSTEP Problem!

I have an HP 9000 735. I tried to install NeXTSTEP 3.3 on it, got it to install on an external drive. I get the NeXTSTEP boot screen, checking disks, blah blah.. then a kernel problem something about the jupiter audio onboard. then it stops and reboots the machine. I tried reinstalling, same problem. Is my cpu board bad??

Possibly.

How much memory is installed? Which graphics?

I have 144MB of RAM, Firmware is 2.6, 99MHZ CPU and CRX24 graphics.

You're good there. Try it with a different I/O board I guess.

You do have the 735 I/O board and not, say, a 720 or 730 I/O board? If the network connector is on a separate slide-in module, you have the 735 I/O board. I have no idea what happens when you put a 735 CPU board with the older I/O, but since from a chassis point of view they're fully interchangeable, I have to ask.

Yep, it's a 735. Soooo close!

Been there, tried that, the I/O board needs to match the CPU board or the machine won't POST.

Actually it's not *that* surprising, since part of the machine identification information used (and displayed) by the PDC resides on the I/O board (as well as the PDC itself) - in other words, it's the 735 I/O board which makes it a 735, as opposed to a 720...

Another fun thing to do on a rainy day, is to mix 735 (or 720) boards from systems of different speeds: mixing e.g. a 66MHz 720 CPU board with a 50MHz 720 I/O board will create a system where the OS believes (as told by the I/O board) that it runs at 50MHz, while the CPU runs at 66MHz because the clocks are separate. And then ntpd goes nuts trying to adjust your clock :mrgreen:
