Note: This is the error reported by "BSD/Mac68k Booter" for /netbsd.new
(earlier I thought the error was something to the effect that the file
was in a format that the BSD/Mac68k Booter couldn't execute):

Booting...
transparent = 1
Huh????

Boot error: Failed to read header from kernel image - read 0 bytes.

*********** Boot Stopped. ***********
Boot error: kernel_parse(COUNT_KERNEL) failed
