Please note that with a Zip GS in the system, the system will always
report an error, even if none exists. You will get an 05xxxxxx if DIP
switch 1-4 is ON, but if that's off, you're likely to get 0Bxxxxxx
(not on all Zips) or 0Cxxxxxx errors. If you suspect a real problem,
then you can either switch off the Zip (1-6 off), or remove the Zip
from the system and try with the normal processor. Do all
modifications to DIP switches or cards in general with the computer
off, as usual.
--- End quoting

   Therefore, if you have an accelerator or other cards in your system,
remove them before trying the self test.

   Should not at all. There is no software method to even detect what
version of the VGC to my knowledge. Even if it could be detected, the
presence of an older VGC will have no effect on the execution of any
version of the system software, other than providing occasionally
incorrect video output.

>Is this error code related in failing to install System 6.0.1 ?

   Nope, no system software affects the hardware inside the GS.  Try
removing *all* cards, joysticks, etc from the GS except for the bare
minimum of only the GS, keyboard and monitor. Turn on the system, and
run a self test. If it succeeds, the problem is somwhere in the
hardware you just removed, and can be isolated.
