Re: I documented 10.1 installation onto a blue and white G3:

[Chris Tucker <capa150%gmail.com@localhost>]

Hello, I am not familiar with netbsd-current and I've never installed it.

I was able to install 10.1 on Qemu (UTM) using one of the config files here:
https://github.com/adespoton/utmconfigs

If I recall correctly, I used one of the Classic MacOS 9.1 UTM config
files there. This link:
https://github.com/adespoton/utmconfigs/blob/main/Mac%20OS%209.1%20(config%20only).utm.zip

But I had to play around to actually get that to work: Try opening
that config file, then additionally make the following changes to it.
I got the following to work on my Macbook Air M1 running UTM:

(Make sure have the netbsd 10.1 (or your netbsd-current) ISO "loaded"
in the UTM drive)

System menu in UTM prefs for the macos 9.1 config file:
cpu: default
cpu cores: 1
RAM: 256megs

Qemu menu:
QEMU Machine Properties: via=cuda

Input menu:
USB support: Disabled

Network menu: Emulated Network Card: tulip

Then try booting it with something like boot cd:,\ofwboot.xcf netbsd
