[Coco] NitrOS9 Boot Help

[Bill Pierce]

Vincent,
1st,  Do you have a 6309 CPU? If not, then you're using the wrong disk images.
No "standard" off-the-shelf Cocos came with a 6309, so most likely you have a 6809 CPU.

2nd, booting from DriveWire, only images ending in "_dw" will boot, all others will fail.
Since you are getting the "OK" prompt after "DOS", this suggests you are trying to boot a 6309 image on a 6809. The image you need is:

nos96809l2v030300coco3_dw.dsk

This image will boot on both 6809 & 6309.

3rd... Is there an offset set in your HDBDOS rom? This will also produce an "OK" prompt after "DOS" if there is no VHD with an RSDOS partition.
To find out type:

PRINT PEEK(&HD938)

If the result is 0 then you're fine. If it's non-zero then you need to set your offsets to 0 for a disk image.
Use:

POKE&HD938,0:POKE&D939,0:POKE&D93A,0

Then type "DOS"

4th... No OS9 disk can read directly by RSDOS/HDBDOS. You will not get "DIR" results with any image from the repo while in RSDOS/HDBDOS. Only the "DOS" command will produce results and then ONLY on bootable disks (disks with an OS9Boot file).

As for the CocoSDC, I don't own one, so I can't tell you how it should react.

As Tormod pointed out, use DriveWire4 as DriveWire3 is a bit out-dated and has no where near the features of DW4.

Subject: [Coco]  NitrOS9 Boot Help


Greetings all -- After trying to Google help on booting NitrOS9 on my Coco3
and
coming up with nothing that has worked for me, I am hoping someone can
point me
in the right direction.  I've been trying to boot NitrOS9 for the
longest time
and can't seem to get it going.

My setup:
* Coco 3 with serial to USB cable to
my PC
* HBD-DOS v1.4 DW3 cartridge
* Drivewire 3 & 4.  (I've tried both)

I
mount the NitrOS9 disk image to drive0 in Drivewire and type "DIR" on the
Coco
and all I get is an "OK" back.  When I do a "DIR", I get "DRIVE=0
FREE=63" 
(blank floppy?).

Here are the NitrOS9 files:

I've also tried the
nos96309l2v030300coco3_cocosdc.dsk with the CocoSDC and
all I get when EXEC is a
scrambled screen.

Any help would be appreciated.  Thanks.
