Yes, there is something that can be done - you will need to edit
/usr/bin/bosboot and then rerun bosboot -a. If you can temporarily get back
that 8MB card to get back to 16MB, then you won't need to boot in maintenance
mode; otherwise, you will.
After you've booted your machine, (after running /etc/continue if in
maintenance mode), edit /usr/bin/bosboot. Look for a comment which will say
something like "If there is only 8MB of memory, must compress the RAM disk".
Comment out the "if [ "$sizemem" -le 8192 ]" the "then" that follows, then
the "fi" which follows that. Write the file back to disk. sync if you
are in maintenance mode. Then, run bosboot -a. You should then have
a system which will boot in 8MB.
