Hi Malcolm,

QDOS/SMSQ boots from ROM. That takes just a few seconds. If you just want
to use QDOS/SMSQ, here you are.
If you want to start Linux, you simply execute the Linux loader, which is
an QDOS/SMSQ application. You can do that from the commandline or your
bootfile or any other basic program. That will start the Linux kernel,
which will leave QDOS/SMSQ and take control over the Q60.
To get back to QDOS/SMSQ you shutdown Linux and reboot QDOS/SMSQ.
Q40/Q60 Linux is no QDOS/SMSQ application except for the loader. It is
directly based on the Q40/Q60 hardware just like PC Linux is based on the
Intel PC hardware. This is much more than just an optimization, it is a
complete operating system port. An enormous work - Richard deserves the
highest respect for this achievement.
BTW if you want to run a QDOS application while using Linux on a Q60, you
can use a special version of UQLX. Unlike emulators on a PC it can run QDOS
programs native on the 68060, which is of course a lot faster.
All the best
Peter
