A/UX Install Issues

[tlc630]

-v = verbose

Well, no joy with that solution...seems like it's having trouble booting the Kernel. Trying the 'verbose' option yields nothing. Freezes in the same spot.

I'll keep playing...but any other suggestions are welcome. :beige:

Where are you? I have some A/UX compatible CD-ROM drives, cabling etc. if you are anywhere near London.

What kind of media did you burn the images onto? CD-R media has been sold in 700 MB capacity for years, but when A/UX was written the capacity of a CD was 650 MB. I burned my copies onto 650 MB CD-R media, never tried 700 MB because I assumed A/UX would throw fits. Might be worth a try...

Also, many old CD-ROM drives had issues reading CD-Rs at all - some of which could be alleviated by burning at the slowest possible speed (1X is an hour to burn a full 650 MB disc if memory serves...).

beachycove: Alberta, so...that probably won't work...thanks though...

Blinkenlightz: I had a spindle full of I don't know what kind of CD-Rs, which I tried at the lowest speed my computer can do (4x). Then I picked up some Sony CD-Rs, not sure on the size, I think 700 MB. I'll have to see if I can get 650MB to try, if those can even be found anymore.

On another note, anyone have a known-good A/UX backup image they can point me in the direction of? If I know the image is good, I can rule that out.

I think the CD capacity is a red herring. All my installation disks are 700MB Sony CD-R created with ImageBurner at 1X speed on a G4 Powerbook. They all work without issue.

Agreed. With the number of different discs and images and media I've used, I think I can rule that out.

My list of things to rule out is:

1) Hardware (ie. IIsi)

2) Drive (CD 300)

3) SCSI Voodoo

4) Disk images (CD and floppy)

I think I've eliminated 2 and 3, since the discs are readable in System 7. 1 is difficult to rule out, since only my IIsi is A/UX capable, so I can't test the install on another machine. I've tried taking it down the the minimum, which isn't much (ie. remove network card). No matter what I try, I always get stuck on the 'This is the point of no return for launching an A/UX kernel.' message. CD or boot floppy image, maybe? Setting the verbose flag gives no further information on why it stops at this point. Obviously, it IS having trouble loading the kernel, but I have no idea why.

Incidently, anyone try the images available at http://macintoshgarden.org/apps/aux-apple-unix-68k-version-301-31-update? Are they good? (CD and floppy?)

It may be CD image related. When I did my A/UX install probably around a decade ago I used the windows version of cdrtools which essentially was using a DOS prompt. Might find more info on this page which I made around the time of the installation: http://aux.preterhuman.net/

Solved!!!

Sort of...

I finally managed to acquire a (much coveted) SE/30, and I tried to get an A/UX install going on that, and it got me right through to the partition screen no problem. So it would seem that something about my IIsi is causing the problem...but what, I wonder...?

Do you have any way of changing the RAM SIMMs? I had a similar problem with my SE/30; the kernel would freeze more or less at the same point. I had to replace the ram SIMMs and everything worked fine. All versions of UNIX I have ever worked with somewhat "stress-test" the memory.
