Figure 2. EXM Slot Numbering.
ID
is a hard-wired ID value. Each EXM has a unique ID value.
OB1/OB2 are two bytes of option information.
Note that all slots are listed on the screen even if the actual system configuration does
not have all the possible EXM slots. All slots
not
occupied by an EXM module
should show an ID of FF and OB1/OB2 of 00 00 indicating that no EXM is
present.
To add or change an EXM configuration, use the cursor keys (arrows) to move
between the fields on the screen. Move the cursor to the appropriate slot entry and
type in the correct value.
The
ID
for the EXM-9 should be set to
F6
h.
OB1 should be set according to the following bit definitions:
00 EXM-9
disabled
03
IDE interface enabled, floppy controller disabled
05
Floppy enabled, IDE interface disabled
07
IDE and floppy interfaces enabled
Table 2. OB1 Configuration Bit.
For instance, a typical OB1 value is
07
h, representing IDE and floppy interfaces
enabled.
