[Coco] partial OS9 boot from hard drive (back on topic)

[George Ramsower]

OS9 is synonimous with pulling hair, running down the street screaming and 
going postal.

The biggest nightmare with stock OS9 L2 is the bootlist order bug(blob).
I think this might have something to do with your problem. If I understand 
it correctly, it has to do with modules going beyond the 8k block and being 
split up. A fractured module won't work.
Also, I don't see the need in patching anything except a copy of h0.dd, 
making it the /dd.
Modify and use the copy. Your hard drive interface card should have come 
with the device descriptor on the disk it came with.

Now you don't have a /h0 DD in your boot.

I have cc3go in my boot file as the last entry. It isn't in the cmds 
directory. I don't know if this is necessary or not. I do know it's only 
used once in the boot up.

Shell is loaded from the default directory/cmds.

grfdrv is loaded from the boot disk/cmds (with unpatched modules)

Here's what I would do because it works for me.

Start over with unpatched modules.
While running with a working OS9,  type:
save /h0/ddh0.dd h0    < this will save the device descriptor ( h0 ) to disk 
with the appropriate file name, ddh0.dd.
patch THAT file from h0 to dd and place it in your config directory.

create a new boot list using that descriptor instead of the floppy dd 
descriptor.
put cc3go in the bootlist as the last entry.
Shell goes into the default drive/cmds directory
grfdrv goes into the boot disk/cmds directory

Configure the bootlist so that related modules are more closely organized... 
here's one of my bootlists...
Try to use this order in your bootlist as much as you can to avoid the BLOB.
 Lose T3.dd and MODPAK.  You probably won't be using it. This is the driver 
and descriptor for the 300 baud modem pak. My T0-T3 point to my custom comm 
ports.
 Lose T1.dd and SIO . You won't be using the bit banger for communications(I 
hope)
