I have an SCSI hard connected to the front of the SGI challenge system. Its the only HDD connected to system right now and was working fine but now for some unknown reason its controller number become 1 instead of 0. I am attaching the screenshot of the terminal running HINV command. Now I need to change this SCSI controller number to 0 so that I could install IRIX and other software on it., anyone please suggest the solution, how to change the controller number back to 0
