Your standard.bl is just what it should be. That means there is some
hardware or OS problem in creating the boot disk.
Did you boot with the 80 track disk on your real Coco or an emulator? If
you can boot the 80 track disk on your Coco, can you read text files
from any directory and ident modules from any directory without errors?
You will not be able to correctly create a boot disk unless you boot
from the NitrOS-9 distribution disk. If you can create a boot disk with
an emulator but not with your real Coco, I would suspect a hardware
problem either with the controller (or MPI if there is one) or a drive
problem. At least check the drive speed with the strobe markings, as
OS-9 is more sensitive to speed deviations than Disk Basic.
You descriptions of the problem match random read/write errors which can
have several sources. However, your first task is to prove you can read
everything on the 80 track distribution disk using your Coco.
