 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
