Setting Flash Memory Bank A/Bank B Header (J9) (Pins 1 And 2); Setting System Controller Selection Header (J2) - Motorola MVME2100 Installation And Use Manual

Setting Flash Memory Bank A/Bank B Header (J9) (Pins 1 and 2)

Bank A (soldered memory) consists of four 16-bit devices that are
populated with 8-Mbit flash devices (4MB). Jumper header J9 (pins 1 and
2) provides selection between the Bank A (Bank 1) or Bank B (Bank 0)
configuration (for PPCBug use only).
Bank B consists of 1MB of 8-bit Flash memory in two 32-pin PLCC 8-bit
sockets.
A jumper must be installed either between J9 pins 1 and 2 for Bank A, or
left off for Bank B (factory default).

Setting System Controller Selection Header (J2)

The MVME2100 is factory-configured in automatic system controller
mode (jumper is installed across pins 2 and 3 of header J2). This means that
the MVME2100 determines if it is the system controller at system power-
up or reset by its position on the bus; if it is in slot 1 on the VME system, it
configures itself as the system controller.
Remove the jumper from J2 if you intend to operate the MVME2100 as
system controller in all cases.
Install the jumper across pins 1 and 2 to prevent the MVME2100 from
operating as the system controller under any circumstances.
