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
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 F6h.
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 07h, representing IDE and floppy interfaces
enabled.
