Floppy Interface
The floppy-drive interface of the coolMONSTER/PM uses a 2.88MB super I/O floppy-disk controller and
can support two floppy disk drives with densities that range from 360kB to 2.88MB.

Notes
: (*) To protect the external power lines of peripheral devices, make sure that:
-- the wires have the right diameter to withstand the maximum available current
-- the enclosure of the peripheral device fulfils the fire-protecting requirements of IEC/EN 60950.

Configuration
You can configure the floppy disk interface in the BIOS Setup Utility. You can choose the 3.5” (common)
or 5.25” drive types with densities of 360kB, 720kB, 1.2MB, 1.25MB, 1.44MB or 2.88MB. Refer to the
Main Menu section of the Appendix B: BIOS Operation chapter for more information on configuring the
floppy drive.
You also can disable the floppy-disk interface in the I/O Device Configuration Submenu.
