	What is this about write protected disks?!  If RS has managed to
	do this, it is a SEVERE blow to the phylosopy behind os9!
	Whatever happened to sweet ol' *ROMable* os9?!

	I don't have os9 2.0.0 yet due to a severe lack of interest on
	behalf of the local Radio Slack store, however, the problem
	you describe sounds like a problem that's been with us from the
	days of os9 1.0.0!
	The problem, if i recall correctly, was that the shell
	gave a silly mask to i$chdir.  It specified that it wanted write
	permission to the directory, thus not allowing a chdir to a
	directory for which you didn't have write permission.

	To fix this problem, either disassemble the shell, and change
	the permission the shell wants when it does the i$chdir, or
	use "debug" to find the i$chdir call in the shell and patch
	a 'lda  #$07' (or whatever the mask is) just preceding the
	i$chdir to not include the the write bit.

	If anyone is interested, I could find the location(s) and
	report back in a few days with a patch.
