[Coco] OS9 Lev1 Ver2 / NOS9 Lev1

[Chester A Patterson]

Are not these bugs ironed out in Nitro OS-9 Level 1?

I have only the OS9L1 bootfiles, shell and 4 cmds. The rest I copied
over from NOS9L1, including OS9Gen & Cobbler.
So far all work well, just this pesky boot problem.

I see the DECB requirement to read "OS" as the first two chars read from
disk when DOS is executed.

What are the kernel files for OS9L1 (not NOS9L1)?? I've saved BOOT,
INIT, OS9 and OS9p2 as they don't appear to be part of the OS9Boot file.

I think BOOT is the file the DECB DOS command loads first, and which
must have "OS" chars as the very first. Cannot they be merged to the
file? There is the third char, 0D. I don't know if it'll be a bother.
Perhaps changing it to NOP?

There is a bug in the counter.  The DOS command puts the boot sector on
track 35 side 0.  OS-9 Level 1 Version 2 puts it on track 35 which is on
side 1 and not 53 tracks from track 1 on side 0.  If you can patch that
one, I want a copy, along with most of the OS-9 community.
