A/UX Won't run on Centris 650

I have a full 040, and 36 MB RAM, and a 1GB HDD.  it gets to the end of the loading "this may take a while" and the computer reboots!

I seem to recall that the Quadra 650 needed a small hack to work, like manually copying the system enabler to the install floppy, or some such thing. Have you done something similar on the Centris, and/or do you have on board Ethernet or a supported Ethernet nubus card? A/UX is very hardware specific.

the 040 enabler is on there.  I have onboard Ethernet but its not connected.  What happens is that it lauches the installer off the CD after booting from floppy and when its all done, it switches to a grey screen and ejects the floppy and then it reboots.  Whats going on?

One of the things A/UX seems to do first is configure networking/ other cards etc., so it is  likely attempting to autoconfigure the machine, and not finding what was expected. I believe there is something in the manuals about this. This is why I asked about the Centris 650 System 7 Enabler, and networking in particular. Did the Centris have onboard Ethernet?

Onboard Ethernet yes.  but its AAUI connector so I cant connect it to my network yet.  it also has the real 040 and not the LC version.

its basically a quadra 650 without the lips floppy drive (the quadra 650 floppy drive opening looks like it has lips, the centris just has a slot)

If

it lauches the installer off the CD after booting from floppy and when its all done, it switches to a grey screen and ejects the floppy and then it reboots....
then it is surely installing something, unless maybe that’s not expressed very accurately.

You have followed a set of installation instructions? There are several decent guides out there, though the easiest thing would be just to accept the defaults. Or do you not get that far?

Step 1.  Insert boot floppy

step 2. insert CD

step 3 boot PC

step 4 it loads off the disk and says workgrup server 95

when the bar graph is done after this is when it reboots

This was missing from your steps, did you perform this?

"Additionally, if you are installing A/UX on a supported Macintosh that requires a system enabler in order to boot, you 
can accomplish the installation by copying the necessary system enabler to the System Folder of the A/UX installation
diskette prior to beginning the install." from doc ID 14662

Slightly different?

"You should make a copy of the A/UX Install Boot floppy and then copy the Enabler for the Q610/650 onto this copy. You then boot up from this floppy and install A/UX as usual. Finally, you'll need to copy the Q610/650 Enabler onto the A/UX MacPartition (or whatever MacOS disk you will use when starting up your Mac and booting A/UX); do this by first booting off a boot floppy or boot CD and then copy the Enabler over. You do not need to make any changes to the A/UX System Folder (i.e. the System Folder used under A/UX)." from http://christtrekker.users.sourceforge.net/doc/aux/faq.html#InstQuadra

I have found that A/UX will not recognize even an Apple screen at resolutions like the one you are using without some work, and never on installation.  It really, really wants stock, period hardware. 

When the machine goes dark at the end, are things still happening on the drives? If so, then I’d wager that the trouble is the screen. Do you have an adapter that can force a 640x480 resolution?

If that doesn't work...

In the video, you mentioned that you were told it was a full 040 with FPU, you should visually verify this.  You just need to open it up and check the number on the processor
