[A/UX] Drop-in clean A/UX install image for SCSI2SD

You can add the lido.img file using the exact commands detailed in the page linked by aladds:

dd if=lido.img of=disk.img seek=64 bs=512




Write the SCSI2SD image first, then overwrite the driver with the lido image by running the above command.

I got the sad mac 000000F/000021 error on my SE/30 and fixed it by writing the lido driver to the SD card. After that it (eventually) booted right up.

Hi everyone,

New to the forum but browsing for a while. I’ve caught up on this thread and A/UX just intrigues me to no end. 
 

I know you all are talking about imaging to something like SD2SCSI but I don’t use those things. I’m a vintage hardware purist. Do you have a working image that I could image onto a real SCSI hard drive ?  How would I do that with only my vintage Macs being able to use SCSI?  
 

Your image also assumes large SD cards (over 4GB). I want to try A/UX on my 1GB Iomega Jaz drive. Thoughts?

The image comes with a configuration, so it's easy to image onto an SD card with Etcher and apply the configuration with the scsi2sd utility.

However, if you are not using a SCSI2SD, it will probably be easier to install from the CD, since the image is tailored for the scsi2sd configuration.

Good luck installing it from CD however. It is a difficult process and, depending on your hardware configuration, it may not even work at all.

I have a one time installed from CD on a Quadra 800 onto a 1.2GB hard disk. That install is long gone but I do have experience installing it. 
 

I like the thought of changes and updates to the system that have been made which is why I thought of using the image already made.

If you have a Linux box you should be able to find a cheap SCSI PCI card and dd this image to a SCSI drive.

That won't work, because the SCSI2SD configuration also provides multiple virtual drives on one SD card by offsetting them in the image. The virtual drives start at different areas of the image.

FWIW if I dd this to a SATA SSD, then connect that to SATA -> IDE adapter, then an IDE -> SCSI adapter, AU/X does at least boot and try to start up. It complains about not being able to check opt, but I figured that was more due to the size of opt. It also eventually reaches a grey screen, so something is not quite right... but it at least partially works.

It is because /opt is on a different partition on a different virtual drive configured on scsi2sd utility

Is there any way to have a image made available that could be imaged onto a real SCSI hard drive device for a more traditional use?  I’d really like the additions and modifications you have done to this project.

Here's a strange glitch I'm observing on my SE/30 – if you remove A/UX Startup from Startup Items, I can't run A/UX Startup manually – I get the following error:

IMG_9312.JPG

(It used to be 512k.) No editing of the minimum + preferred memory sizes fixes the problem. Has anyone seen this before?

Is there any way the file is corrupt?  That almost seems like a corruption issue.

What happens when you put A/UX Startup back in Startup Items

I know this is a bit old to be digging up, but I managed to fix the Sad Mac/21 error using the lido.img driver from Step 3 here.

And it works (albeit slowly) on my SE/30 :)


May I please know if the lido.img needs to be dd to the start of ALL scsi devices (i.e., SCSI#0, #1, #2 and #3) on the SCSI2SD card) or does it only need to be written just once to the start of the entire SD card, i.e., the start of SCSI#0.  The SD image referred to here in this thread has more than one SCSI device on it, so I would like to know if I need to dd the lido.img just once at the start of the SD or many times at the start of each devices.

I was able to boot the image by following tub’s instructions quoted above.

I have managed today to finally get the AUX SCSI2SD image referenced in this thread to work on my Macintosh SE/30.

However, when I tried to select the alternative boot option of X11 rather than Apple's GUI at the login screen option menu, it was unable to boot into X11, stating simply, 

"xterm: Error 18, errno 22: Invalid argument."

I have rechecked the PATH for the binary and also removed all the arguments to the xterm reference in .x11start but it still can't get into X11 environment.  Please see attached photo.

Anyone knows how to fix this, please kindly advise.  Thank you!

I have managed to start the X11 Session -- just need to create normal user account and login under X session in the A/UX login option menu.

Something seems scripted into the root account that prevents it from starting xterm, even if all references to xterm are removed from .x11start.

Out of curiosity, how much time do you need to boot this image on your se/30 ?

I mean regular boot, not first boot.

Is 3.0.1 or 3.1 faster on SE/30 ?

How would you set up these versions on se/30 ? I tried to flash install iso of these version on my sd card but I wasn’t able to boot from them.

Do you get similar performance as I do ? I did a video of my setup : 






EDIT : I guess I'm just low on RAM and the system keeps swapping, am I right ?

Sorry for the thread necromancy, but I'm having a bit of trouble getting this running on my SE/30. It's got a BMOW Macrominator II and 68MB of RAM, with a SCSI2SD V5.5 hanging off the back. I installed the SCSI2SD configuration on my device, then I wrote the image to my SD card on Linux:

Code:
sudo dd if=Apple-AUX-3.1.1-03a.img of=/dev/sdb bs=1M status=progress

Then I wrote in the lido disk:

Code:
sudo dd if=Downloads/lido.img of=/dev/sdb seek=64 bs=512

First time I tried to boot it, I got the 000000F/000021 sad mac. I cleared the PRAM and forced boot from SCSI ID 0, then 1, both of which just showed me a flashing floppy. Now it only shows the flashing floppy icon. Any thoughts?

Just for ruling out the image, or your hardware, have you tried doing a dd of the original A/UX install CD iso image to your SD card? It should image over and be bootable, if the .iso image file is clean and proper. If that has the same error, then it's likely something with your hardware or the way you're dd'ing it.
