[Coco] OS9 Lev1 Ver2

[Becker, Gary]

You might try looking at IT.DNS (byte $16) of the device descriptor for
the drive using to generate the boot disk. It should be $03 for an 80
track drive. I have never run Level 1 Version 2, so Rogelio may know of
an issue that I am unaware. See his email on this topic.

Actually it's HDB-DOS...
Command DOS does nothing at all, just checks drive 0 for a couple of
seconds then returns to the OK prompt.
So I guess that "OS" thing must be the problem. Does not Cobbler and/or
OS9Boot (from Nitros9 Level1) take care of that?

When you say you tried to boot it and no dice, what exactly did the
system do?

DECB DOS command looks for "OS" as the first two characters on the boot
track. So if the disks you are making have this track in the wrong
place, DECB will come back to a prompt. If it tries to boot but then
fails, then it is a different problem.

Messing around with OS9 Level 1 Version 2. Replaced CCDisk and
associated floppy descriptors with rb1773, DD, D0 & D1 from NOS9 Level
1. All this on a 35 track single sided disk. Boots great. Format a 80
track double sided floppy, cobble it, DED OS9Boot so the DD, D0 and D1
descriptors have the correct cylinder count (&H50) and sides (2). Try to
boot it. No dice. Tried with 40 track double sided. No dice. 80 track
single sided. Nothing. Tried every combination. Nothing. Tried OS9Gen
instead of Cobbler. Nothing. I can boot with the 35TSS disk with 80TDS
descriptors no problem, CHD & CHX to a big disk and all works fine. Just
can't make a big bootdisk. I can make all the 35TSS bootdisks I want
using RS-DOS BACKUP. But that's not the point. What am I doing wrong?
Thanks. /Chester
