First of all, I can't get the installer to see an external cd-rom, works fine off the internal bus, I don't know what that's about.
On this machine, everything works swimmingly until its about to boot off the install cd, it says "this may take awhile" and then text across the desktop says "floating point exception," then it reboots, but it doesn't eject the floppy, and it goes through the whole process again, same error, reboots, until it does the same thing again.
I tried swapping ROMs, swapping RAM... same thing.
When making the start-up floppy, disk copy gives me an error, says there something wrong with the disk image, but then asks to insert another disk. I made 4 of them before realizing they were all bootable, but maybe the problem is there... odd if it would boot and go all through the initial stages before screwing up though.
I am using a fujitsu drive that I haven't set up in anyway yet, unsure of what drivers may be there, so I am not sure if the problem is there, but I have usually had amazing success with the A/UX installer being able to set up drives it has no business being able to set up, and I don't see what a drive has to do with floating point stuff. I was just experimenting to see if the installer would set it up, but I can't even get to that point, so I don't know.
Is this a bad board? What causes a floating point exception?
It almost sounds like a bad floppy drive. Maybe you just need to clean it out or something?

The "floating point error" message sounds weird.
But as far as the installer not seeing an external CD-ROM, you need to be using an Apple CD SC, CD300, or CD300e/i -- in other words, an Apple branded 1x or 2x CD-ROM drive. Nothing else is supported by A/UX. More recent Apple CD drives (4x, 8x, etc.) will work -- with some minor glitches -- once you've already installed A/UX. But for actual installation, you're fsck'd unless you use one of the aforementioned CD drives.

The external cd-rom is an Apple 600e, may explain why it doesn't work if you are right. The Apple CD SC doesn't work for sh!t, never has, will sometimes mount after install, but always gives errors, so I'm ready to toss it (or hack something into it, its a neat box).
The only success I am having (on install) is with the apple internal 24X cd-rom drive from an 8600, so you are way off there, it worked fine on 3 other installs, it's just a pain to work with the box all opened and frankensteined (and 3 curious cats skulking around, they just have to be where you don't want them).
they're not the only cd-rom drives supported, 'cause i tried to install a/ux on my iisi recently with a pioneer cd rom changer DRM-604X and it worked
IIRC there is a "univeral" CD driver on either the CD or the floppy. Also, IIRC, I copied it to a regular Mac OS isntall and it worked fine. It's been a while since I played with A/UX, but I did get it installed on an SE/30 with and old non-Apple CD drive.
