As you can see, the NVRAM only manages options; there is nothing that has to be set for the controller to work:
NVRAM ~~~~~ The A3000 also has a NVRAM configuration which is powered by the same battery which the clock is. It supports the setup of the following:
SCSI Controller ID: This places the onboard SCSI controller at a specific ID location, 7 by default. You can change this to something else, to get a device at 7.
Long SCSI Timeout: This slows the boot process for SCSI drives, for those units which take longer to spin up and be ready.
Synchronous SCSI: This enables Synchronous SCSI mode, which can speed access on some drives. This is fully operational on Kickstart 3.1.
Multiple LUNs Mode: This enables multiple LUN's, which allows for multiple drives at each address.
