[comp.sys.m6809] OS9 bootfiles and other questions

mdk1@cblpf.ATT.COM (Michael King) (02/22/88)

Howdy fellow Color Computer enthusiasts,

This past weekend I was playing around with my OS9Bootfile.  I ran config
and installed the double-sided 40 track device driver for drive one.  I use
the basic Radio Shack 35 track single-sided drive for drive 0 and a Teac
(I can't remember the model number) single sided drive for drive one.
I ran the format command for drive one as: 'format /d1 r 1 "Test Disk"'.
That is, format drive one, one sided, and name it "Test Disk".  The format ran
and gave me a disk that had 720 sectors on it instead of the 630 I would
normally get if I ran it on a single-sided 35 track format.  On this disk I
ran the config again, and made a boot disk to be used in drive 0.  This disk
booted okay and I went ahead from there.  So far I haven't encountered any
problems.  I've loaded the disk down to where there is only 68 sectors left,
and everything seems to run okay.

Has anyone else tried this, and are there any reasons why this is a bad
idea?  Does this work because the drive 0 can read 40 tracks, even though
it is formatted for 35?

In another area, I tried to use the patch that was posted a few weeks ago
by Mark Sunderlin to allow the 2 byte control codes used with terminfo and
termcap.  The patch ran okay, except for the last change:

l cc3io
[some of the changes deleted]
c A2D DB C0
v ^^^^^^^^^^------ modpatch returns and says that it can't find this byte.

What is the correct byte?

One last question, is it possible to run cobbler on a disk twice?  I tried
this this weekend and it trashed my bootfile.  Should I make all the
changes to the system (like xmode and such) and then run cobbler only once?

Thanks for any info,
Mike King
