Error in Gamba's documentation?

[Mk.558]

I've seen a few posting of some smart folks who dive into DeclROMs and other stuff involving the startup boot sequence.

This gets me interested because in Gamba's instructions for installing 8.1 on 68030 machines, and I'm not sure if I found an error not. Perhaps we can shed some light on it.

In the instructions for 8.0, one of the required steps is to edit the gusd resource at the 000010 offset. In that position, I would do the following (for a IIci):

0016 0006 < old
000B 0005 < new

However in 8.1, it says to do the same steps, but :

0016 0006 < old
000B 0006 < new

I've been fighting 8.1 on this machine for almost the entire day, and I'm not sure which one is correct. Shouldn't it be

0005

for the 8.1 as well? I'm going to try both. It only takes 10 minutes to decompress a vanilla 8.0 install :/

Not an error. Here's 8.1 with 0005:




Looks great doesn't it? Hard disk with zero K free, weird errors, hard drive icon is a floppy disk. Here's with 0006:



How do I rate 8.1 on a IIci? Well let me ask you this. Got a 68040 accelerator? No? Don't do it. 24 seconds to open the Chooser. Sluggish. Not SE or Plus on 7.5.5 sluggish, but may as well be.

Still curious about what the difference does internally though. Maybe we'll never know.

Interesting bit of digging there. I’ve actually never tried this hack.

You can plop the OS 8 Finder into System 7 but I’ve never tried that either.

OS 8 on stuff like an SE/30, IIci or IIfx has never made sense to me. 7.1 is great for those and does everything you need, you can drop in 7.5 extensions/control panels to bring extra features into 7.1.

I do use OS 8 on my 40MHz Wombat but I’m still using 7.1 on my faster baby Wombat (an accelerated 475 running at 45MHz).

I got OS 8.1 up & running on my IIfx and I'm pretty certain I followed Gamba's instructions.
It runs well with 32MB RAM.
My install is here: https://macintoshgarden.org/apps/mac-os-81-a-mac-iifx-or-maybe-just-a-68030
I haven't tried it on a IIci yet but it might work.

That's a fun and weird set of misbehaviours!

I especially like the title of the error dialog box. So weird.
