Faster dual boot

If you end up dual booting Mac OS Classic and OSX like me, you’ll notice that the boot menu takes ages to become responsive.

This is because it’s reaching out looking for things it can boot over the network. If you never plan to use netboot you can just turn it off and the boot menu will load much faster from then on.

Disable netboot

Hold CMD + Option + O + F to enter the Open Firmware prompt.

Enter:

setenv skip-netboot? true

Followed by:

reset-all

To reboot the machine.

And of course, to re-enable netboot just perform the same steps but set it to `false instead:

setenv skip-netboot? false
