You must be using the potato installer? The woody installer's
kernel file is named linux.bin, and uses Penguin-19.
With only 12MB of memory, you're better off using potato
anyway. that might not be enough for woody.

You're getting the kernel launched, at least. Were you sure
to launch MacOS holding the shift key down, to disable extensions,
before launching Penguin? I got all sorts of strange things
happening before I learned to do that, although I usually got
farther than you're getting.

One more thought, when you downloaded 'linux' under MacOS, did
you download it 'as binary' not 'as text'? Most web browsers
on the Mac assume it's text if it doesn't have any extension -
one reason the name was changed to linux.bin. That has problems
too, if you have Stuffit or Fetch set up to automatically extract 
Nacbinary encoded files, they will assume from the .bin extension
that they are to decode the file - which will destroy it.
