USB Ports

Four USB 2.0 ports, USB0 through USB3, are accessible using cable assemblies attached to connector J15 and
J16.

USB support is intended primarily for the following devices (although any USB-standard device should function).

Keyboard

Mouse

USB Floppy Drive (This is required for Crisis Recovery of boot ROM)

USB flash disk

The BIOS supports the USB keyboard during BIOS initialization screens and legacy emulation for DOS-based
applications.

The USB ports can be used for keyboard and mouse at the same time that the PS/2 keyboard and mouse are
connected.

11. NOTES ON OPERATING SYSTEMS AND BOOTING PROCEDURES

11.1

Windows Operating System Installation

Windows operating systems installation should follow these steps, or some device drivers may not function
correctly under Windows.

Enable CD-ROM support in the BIOS. Change the boot sequence in the BIOS so the system boots from
CD-ROM first.

Insert the Windows installation CD into the CD-ROM and restart the computer.

Follow the manufacturer’s instructions for installing Windows.

11.1.1

Driver Installation

Drivers are provided on a CD. Please, follow the instructions included on the CD to install drivers for the different
operating systems.

11.1.2

BIOS Setting for Windows

When using any version of Windows, the Operating System selection in the BIOS setup menus should be set to
Win98. Also,

Legacy Audio

must be disabled for Windows to boot properly.

11.2

DOS Operating Systems Installation

User the following sequence to install DOS operating systems: MS-DOS, FreeDOS and ROM-DOS.

Enable the following in BIOS:

Floppy Drive detection

Legacy USB support

Change the BIOS boot sequence so the system boots through the USB floppy drive.

Insert the DOS installation floppy disk into the USB floppy drive and start/restart the system.

Install any drivers needed.

Note:

For DOS Ethernet, set

Operating System

other

in the BIOS.

Note:

DOS Sound emulation is currently not functional.
