Out of curiosity, has anyone suffered/experienced the above phenomenon before? It sounds like no-one else has seen this behaviour before.

The files are on an ISO9660 partition. I didn't make an hfs partition on the C i'm currently trying to boot. The file name was originally netbsd_generic.gz, so when I made a pure ISO9660 (I omitted 31-character extensions. Should I allow 31-character filenames?) the filename of the kernel was truncated to netbsd_g.gz. I'll rename the kernel file to netbsd on a new ISO, and try then new ISO.

I don't know why either. Perhaps we'll leave this issue for now, and perhaps we'll get some ideas later.

I didn't realise OFWBOOT.XCF looks for a NetBSD disklabel, so I didn't create any NetBSD disklabels on the ISO. Might this cause problems?

On an ISO image, what is the difference between partition 0 (aka "ide1/dis@0:0" (correct me if i'm wrong)) and partition 1 (aka "ide1/disk@0:1" (again, correct me if i'm wrong))? I see identical directory listings when I invoke "dir ide1/disk@0:0",
