Do you hae the terminal software set for 38400 baud? That's OF's
native rate AFAIK. Also, check that the NVRAM output-device is also
set to ttya (usually both input-device and output-device default to

Have you actually run the Make Hard Disk Bootable menu item? That
writes a boot block on the disk (partition '0') which starts quik.  If
you're getting the boot: prompt, then that's done properly. If this
message is coming from quik, re-check your quik.conf to be sure you've
properly specified a root partition. But it doesn't sound like a quik
message, because quik would be looking for ext2, not hfs.

I believe I read something about it in the mkisofs or cdrecord
documentation. You copy the code from an existing bootable MacOS CD,
IIRC. Legality is not my area.

You wouldn't be erasing firmware, just the Apple disk driver partitions.
If you won't have MacOS, you won't need them at all.
