[Coco] DriveWire 4 - NitrOS-9 Floppy *BOOTSTRAP!*

[Chad H]

Nice...a lot of chains in that link on the CC3 :)  

Now if I can just trace down how the DriveWire/NitrOS-9 bootstrap is setting
up the serial communications parameters and change it to 115200/2/xor on the
output, I will be good.

Good work Chad, I must have missed the post or I would've told you to do it
just that way.

My Coco 3 has an autoboot feature (part of the Eagle keyboard interface) and
executes DOS after 10 or 15 secs if you don't hit a key. I have track 34
setup with a "dos" routine that runs a basic program that loads hdbdos from
the disk then a menu comes up (RG's RGBDOS menu) and I have it set so after
15 secs of not hitting a key, it does a DOS255 and boots NitrOS9. So I just
turn the Coco 3 on and it'll be in Nitros9 in less than a minute, while I'm
booting my Coco 1 and VCC.

My Coco 1 has no such feature and I rarely use BASIC so I just made a boot
for it the same as you described. It has the floppy boot but defaults to /dd
after it starts which is really /x0. There's a copy of the OS9Boot on the
VHD as well for "reset" warm starts. It works well for me. I do have another
disk set up for hdbdos if I want to work in BASIC and it will boot Nitros9
from drive255. I have the same "dos" program on that disk that starts
hdbdos.

Ok, someone told me this couldn't be done.  Perhaps they didn't understand
what I was referring to..

 

*	I wanted to be able to turn on my CoCo WITHOUT a DriveWire ROM, type
DOS and it 'BOOTSTRAP' into NitrOS-9 on the DriveWire 4 server.

 

I've managed to create a real Floppy that does just that.  DriveWire ROM not
required!  Essientially it is a DriveWire 4 NitrOS-9 floppy that starts the
bootup sequence from the real disk but somewhere along the way it 'switches'
to the /DD image housed on the DriveWire 4 server and seamlessly continues.
