Super I/O Subsystems; Floppy Drive - Kontron ETXexpress-WPM User Manual

8. Super I/O Subsystems

The Winbond W83627HF chip is located on the ETXexpress Carrier Board, not the
ETXexpress-WPM Module. The chip provides support for legacy I/O devices such as
the floppy drive, IrDA, PS/2 keyboard, PS/2 mouse, parallel port, and 2 x serial ports.
Please note that the Winbond W83627HF is an optional baseboard feature; the BIOS
installed on the ETXexpress-WPM supports it, but if it is not present, or if another SIO is
used, then you must install a different BIOS, as appropriate, using a Flash utility.

Floppy Drive

The ETXexpress Carrier Board BIOS provides support for a floppy drive.
The floppy-disk interface shares signals with the parallel-communication interface. The
floppy interface is limited to one drive (drive_1). A standard floppy cable has two
connectors for floppy drives. One connector has a non-twisted cable leading to it; the
other has a twisted cable leading to it. When using the floppy interface you must
connect the floppy drive to the connector (drive_1) that has the non-twisted cable
leading to it.
Configuration
The floppy drive interface uses I/O and IRQ resources. The resources are allocated by
the BIOS during POST configuration and are set to be compatible with common PC/AT
settings.
You can configure support for the floppy drive from the BIOS Setup Utility. (Press the
Delete button during reboot to see the BIOS Setup Utility.)
Go to the Advanced Menu->Floppy Configuration Submenu.
For complete information on BIOS setup options, see the BIOS Operation section in the
back of this manual.
