Long boot delay - Amiberry on MacOS

[rkelleyrtp]

Greetings everyone,

I am running the latest Amiberry (7.0.8) on my M1 Mac (ARM) using AmigaOS 3.2. For some reason, I have a very long boot delay (+20secs black screen) until the workbench desktop starts to appear. This happens regardless if I boot from either floppy or hard disk. I am very new to Amiga (and Amiberry), so I am sure something is misconfigured on my part. Using a number of online guides, I don't see any reason for the delay. I use the exact same config on my Linux desktop, and Amiberry boots the OS almost instantly.

For details, I use the standard A1200 Quickstart configuration with 4MB expansion, the floppy disk is set to TURBO speed, and I am using a 3.2 install disk (ADF) to boot the system. I can't get the system to boot any faster. Are there some hidden options I need to look at?

Perhaps you're using the accurate CPU speed setting? That week emulate the real CPU speed, and the boot process will be slower due to that. Try setting the CPU speed to Fastest, instead.

Thanks for the reply. I tried all sorts of settings: "fastest CPU speed", different ROMs, different WorkBench versions, etc and nothing has shortened the boot delay.

Strange, then it might help if you posted your config here, so we can see what's wrong.

I have the same problem on my M4 Mac with the Amiga 3.2 ROM (Amiberry and FS-UAE). This isn't a problem with 3.1. I chalked it up to a change in 3.2 boot behavior.

See: https://www.exxosforum.co.uk/forum/viewtopic.php?t=6948 and https://amigastore.eu/en/index.php?controller=attachment&id_attachment=63 ( I haven't tried tinkering with the ideas in the FAQ)

But this doesn't explain why it is fast on the Linux machine.

3.2 ROMs have the delay built-in, while waiting for HDDs to become available.
The same thing would happen on a real Amiga with the same setup, I believe.

On Ubuntu 25, it's a 10 second delay from start until the Kickstart screen shows up, when using ROM 3.2.3.
