Bit 1 - Reserved for future use.
Floppy Drive Enable - Use to enable or disable the floppy drive. Please note that only one
floppy drive controller per system can be enabled at any one time. If the EMC system requires
an EXM-16 or an EXM-MX running with the EXM-FDM, disable all but one floppy drive.
Floppy Drive Setup
Refer to the pertinent EPC manual for a detailed description of how to change the configura-
tion information stored in battery-backed RAM. In most cases, invoke the BIOS setup func-
tion by using CTRL-ALT-ESC from the DOS command prompt. Be sure to define drive A: as
a 1.44M 3.5 inch drive.
Port Conflicts
Avoid interrupt and address conflicts due to multiple serial or parallel ports with the same
address or interrupt. Be sure to either disable unused serial or parallel ports, or set them to a
value that does not conflict with other ports in the system.
Note that in general attaching a mouse to a serial port only works on COM1 or COM2.
