Overview of Start-up Procedure
The following list identifies the things you will need to do before
you can use this board, and where to find the information you need
to perform each step. Be sure to read this entire chapter and read all
Caution notes before beginning. Hardware Preparation
To select the desired configuration and ensure proper operation of
the MVME177, certain option modifications may be necessary
before installation. The MVME177 provides software control for
most of these options. Some options cannot be done in software, so
are done by jumpers on headers. Most other modifications are done
by setting bits in control registers after the MVME177 has been
installed in a system. (The MVME177 registers are described in
Chapter 4, and/or in the Single Board Computers Programmer's
Reference Guide as listed in Related Documentation in Chapter 1).
The location of switches, jumper headers, connectors, and LED
indicators on the MVME177 is illustrated in Figure 2-1.
The MVME177 has been factory tested and is shipped with the
factory jumper settings described in the following sections. The
MVME177 operates with its required and factory-installed Debug
Monitor, MVME177Bug (177Bug), with these factory jumper
settings.
Settings can be made for:
? General purpose readable jumpers on header (J1)
? SRAM backup power source select header (J2) (optional)
? System controller header (J6)
? Thermal sensing pins (J7)
? EPROM/Flash configuration jumper (J8)
? Serial port 4 clock configuration select headers (J9 and J10)
Refer to Table 2-2 to configure the jumper settings for each headerThe general purpose readable jumpers on header J1 can be read as I/O control
register 3 (at $FFF40088, bits 0-7) in the VMEchip2 LCSR (see Chapter 4,
VMEchip2). The bit values are read as a 1 when the jumper is off, and as a 0
when the jumper is on.
2. On the MVME177, pins 7 and 8 (bit 3) are removed for board ID and the bit
value is reserved.
