For anyone with RGBDOS or HDBDOS and a hard drive partitioned for both
OS-9 and Disk Basic, here is a way to test automatic booting to OS-9 at
power up. This is not the best way but does not require creating a
special boot disk with a new Boot module or modifying a ROM.
Both RGBDOS and HDBDOS cold start with the floppies off and look for
AUTOEXEC.BAS on drive 0 of the Disk Basic portion of the hard drive.
Just make that program turns on floppy access and issues the DOS
command, have both your floppy and hard drive turned on before powering
up the Coco, and you will get a feeling for auto booting OS-9 from the
hard drive even if it is much slower.
The code for AUTOEXEC.BAS might be
10 DRIVE OFF: DOS0
which turns on the floppy access and accesses drive 0 for the DOS command.
