System Controller Submenu - Xycom XVME-655 Manual

System Controller Submenu

The XVME-655 automatically detects if the board is in the system controller position
(the left-most slot of the VMEbus chassis). This condition controls whether system
resources will be provided by the XVME-655 or another VMEbus processor. System
resources are VMEbus Arbiter, BERR timeout, SYSCLK, and IACK daisy chain driver.
These resources must be provided by the module installed in the system controller slot.
You cannot change the field that reports the status of the XVME-655's system resources.
