Default Re: Gemini 80-Bus System

This maybe significant. Using disked I command drive A reports 340 cylinders
this is beyond the end of the disk. A websearch gives 320 cylinders for
rodime 201. The bios appears to have the wrong DPB.

Just maybe that was why the transistors that drive the stepper motor in that
the bios tried to seek beyond the end of the disk (I don't know).

Just check on your system how many cylinders the bios is set for using
disked I command.
