CoreModule/PC Technical Manual
2-4
The SETUP function within the ROM-BIOS can be accessed either with a "hot-key" entry (CTRL-
ALT-ESC) during POST or through the SETUP program provided on the CoreModule/PC Utilities
Diskette. The SETUP function is used to specify all of the configuration parameters stored in the
board's nonvolatile Configuration Memory.
Table 2-3 lists the main functions which are controlled by the contents of the nonvolatile
Configuration Memory. Use of the SETUP function is discussed in Chapter 3 and in Appendix A.

Table 2-3. Configuration Memory Options
The CoreModule/PC is shipped with a set of preprogrammed selections. If the Configuration
Memory is ever programmed in such a way that it is impossible to boot or regain control of the
system, a shorting block can be installed temporarily on J2-7/8 to defeat the Configuration Memory
and use the defaults instead. The system can then be reconfigured using the SETUP function.
2.2 DC POWER INPUT
The CoreModule/PC requires only +5V (±5%) for normal operation. The ±9V for RS232C (serial
port) is generated onboard. If a 12 volt Flash EPROM is to be programmed in the byte-wide socket,
typically +12V at 30 mA is required while programming the Flash EPROMs. Check the
manufacturer's specifications for the device you use. (Jumper W4 must be installed when
programming +12V Flash EPROMs.) Power is supplied via the 8-pin Power Connector J5. See
Figure 2-1 for the location of this connector and Table 2-4 for its pinout.
The power requirements of the CoreModule/PC depend on several factors, including what functions
are present on the board (e.g. DRAM and byte-wide memory devices), and what peripherals are
connected to the board's I/O ports (e.g. keyboard) or bus header. For example, a MiniModule video
