Enter the total number of EXM card cage connectors in the backplane (not the
number of slots in the chassis - count each EXM module or faceplate, then add two if
using the EMC-FDM) using the arrow keys to display the number. Note that in some
systems, the EXM-FDM floppy drive module consumes the two highest numbered
slots on the backplane, both of which must be included in the total number of
2
available slots.
As a "worst case" configuration example, if an eight-slot backplane is set for only
four slots, all EXMs above that fourth slot will not configure. (The only exception is
the video card, which auto-enables to allow for error recovery.) Continuing with this
example, the system would not boot if the boot device was located above the fourth
slot. Information would be cleared for the missing four slots, and would have to be
re-entered once the number of slots is corrected.

EXM Setup Screen

The EXM setup screen is used to configure EXM expansion modules in the system.
It is displayed by pressing the F2 function key from the main setup screen. The
EPC's battery-backed RAM holds identification and configuration information for the
number of available EXM slots entered in the EXM Main Setup Screen. The BIOS
displays the configuration information in hexadecimal format. The EXM Setup screen
for a system with
EMC-FDM in slots 6 and 7, and an EPC-23 in slot 0 might resemble the following:
RadiSys EPC-23 EXM Setup, System BIOS V3.06

0 FF 00
1 ED 01
2 7D 07
3 DB C1
4 D5 C1
5 DE 00
6 7C FF
7 FF 00
ID is the unique EXM-ID number.
OB1 and OB2 are option bytes 1 and 2.
The option bytes interpretation is unique to each EXM-ID.
See the EXM user manuals for the semantics of the option bytes.
