Hardware Installation

Installation in a Cubix Enclosure

1. Configure the hardware options as described in Chapter 2.
2. Gain access to the backplane. Typically this requires removing the cover from the enclosure.
3. Power down the enclosure or group in which the BC will be installed (if the BC is being installed in a Fault Tolerant subsystem, only the group that will contain the BC needs to be powered down).
4. Seat the BC into the appropriate group in the backplane.
5. Secure the BC with a screw on the end bracket.
6. Install any peripheral devices required in the enclosure. Instructions for peripheral device installation may be found in the documentation accompanying the enclosure.
7. Install any adapters required to provide connectors for peripheral devices as described later in this chapter.
8. Connect the cables to all peripherals and I/0 connectors (refer to Chapter 2 - Hardware for connection information).
9. Reassemble the system as necessary.
10. Apply power
11. Use a monitor and keyboard to verify that the system is functioning properly. Monitor, keyboard and mouse support are provided through a multiplexor or via an adapter board as described in the Optional Video, Keyboard & Mouse section later in this chapter.
12. Run the BIOS setup utility to configure the CMOS (refer to the American Megatrends, Inc. BIOS Configuration Program User's Guide).
13. Install software as specified in the Software Installation & Configuration section of this chapter. Instructions to configure the 10 Base-T Ethernet drivers necessary to use the integrated Ethernet controller are included in the appendices.

Optional Video Keyboard & Mouse

The video, keyboard, and PS/2 style mouse signals are normally cabled from headers on the top of the BC board to a Cubix multiplexor where they are ultimately brought out to standard connectors and attached to a monitor, keyboard, and mouse. If a multiplexor is not used, Cubix can provide an optional adapter. This adapter is a printed circuit board and bracket that provide an interface between the BC headers and the Mini-DIN 6 and HD DSUB-15 connectors needed to connect a VGA monitor and PS/2 style keyboard and mouse. These optional connectors may be installed in an empty slot (where the end bracket of a board would normally be), or in the additional connector space of an auxiliary junction panel. Refer to "Peripheral Adapter Installation" for mounting instructions.

Optional LPT1

An optional parallel port may be added to function as LPT1 on the BC. This requires a Cubix LPT1 printed circuit board adapter and bracket which provide an interface between the BC header and the DB-25 connector. The optional connector may be installed in an empty slot (where the end bracket of a board would normally be), or in the additional connector space of an auxiliary junction panel. Refer to the Peripheral Adapter Installation section later in this chapter for mounting instructions.

Optional COM2 and Mouse

An optional second serial port may be added to function as COM2 of the BC. A PS/2 mouse input port may also be added. If the optional video, keyboard, and mouse adapter previously discussed will be installed, it is not necessary to include the mouse option on this adapter. Connecting COM2 and the optional mouse requires a Cubix printed circuit board adapter and bracket, which provide an interface between the BC header and the DB-9 and Mini-DIN 6 connectors. Both the COM2 and mouse interfaces are provided on the same adapter. These connectors may be installed in an empty slot (where the end bracket of a board would normally be), or in the additional connector space of an auxiliary junction panel. Refer to the Peripheral Adapter Installation section later in this chapter for mounting instructions.

Peripheral Adapter Installation

Follow the steps below to install optional Cubix adapter boards for peripheral devices such as video, keyboard, mouse, and LPT1.

1. Install the Cubix adapter in a panel opening on the system. Typically, an opening provided for an empty board space is dedicated to the adapter. In this case, install the bracket next to the BC board that requires the adapter port and tighten the screw firmly.
   Alternately, if the adapter is being installed into a Cubix auxiliary junction panel, the bracket provided with the adapter should be removed. Unscrew the connector from the bracket and install the adapter into the desired panel opening.
2. Connect one end of the provided cable to the appropriate header on the BC board. The pin-one side of the ribbon cable is marked with a colored (blue or red) stripe. Pin one on the BC box header is labeled with a triangular arrowhead. Align the pin-one side of the ribbon cable with pin one on the header.
3. Connect the other end of the ribbon cable to the adapter. Pin one on the adapter's box header is labeled with a triangular arrowhead. Align the pin-one side of the ribbon cable with pin one on the adapter.
4. Plug the peripheral device's cable into the connector.

Cubix Mouse/Keyboard Multiplexing Software Installation

DOS Environment

The Cubix DOS device driver CBXMOUSE.SYS provides mouse multiplexor support as well as remote mouse and keyboard support.

NOTE: A mouse driver (e.g. Logitech's MOUSE.COM or Microsoft's MOUSE.EXE) must be loaded for CBXMOUSE.SYS to provide mouse support.

To install this driver for use with the DOS operating system:

1. Copy the CBXMOUSE.SYS file from the \DOS directory of the Cubix Mouse/Keyboard Multiplexing Software diskette to the root directory of the boot drive.
2. If present, remove the following line from the CONFIG.SYS file:
   device = bcsetup.sys
3. Add the following line to the CONFIG.SYS file in the root directory of the drive:
   device = cbxmouse.sys

This sets the following defaults:

• Mouse Multiplexor Support Enabled
• Remote Mouse Support Enabled
• Keyboard Type 101/102 Keys

The following is a list of options that may be used with CBXMOUSE.SYS. Place options on the same line in the CONFIG.SYS file. Command line options are not case sensitive.

Table 3-1
CBXMOUSE.SYS Command Line Options

All Cubix mouse software is designed to be used explicitly with Logitech PS/2 style mice. If non-Logitech mice are to be used, the command line option -nl should be entered in the config.sys file following the mouse emulation software filename:

device = cbxmouse.sys -nl

The -nl option disables the synchronizing algorithms specific to Logitech mice. As a result, mouse multiplexing is not supported. However, remote mouse support will still be available.

4. Reboot the Cubix processor to allow the modifications in the CONFIG.SYS file to take effect.

Windows 3.1x Environment

The Cubix virtual device driver CBXMOUSE.386 will allow a mouse to function properly if it is attached directly to the Cubix processor after Windows is invoked, or if it is attached through a Cubix multiplexor and multiplexed to the Cubix processor after Windows is invoked.

To install this virtual device driver with Windows:

1. Install CBXMOUSE.SYS as described in the DOS Environment installation section.
2. Copy the file CBXMOUSE.386 from the \WIN31X directory of the Cubix Mouse/Keyboard Multiplexing Software diskette to the Windows SYSTEM directory (usually \WINDOWS\SYSTEM).
3. Modify the [386enh] section of the Windows SYSTEM.INI file (usually in the \WINDOWS directory) to include the line:
   device = cbxmouse.386
   and, if present, remove the line:
   device = vhotfix.386
4. Reboot the Cubix processor to allow the modifications to take effect.

Windows 95 Environment

The Cubix Windows 95 mouse driver provides PS/2 mouse support on Cubix processors running Windows 95.

To Install the Cubix PS/2 Mouse Driver for Windows 95:

1. From the Windows 95 Control Panel, select the Add New Hardware icon.
2. From the "Add New Hardware Wizard" window, click on the Next button.
3. When prompted about whether or not Windows should search for the new hardware, select NO and click on the Next button. A list of hardware type options appears.
4. From the Hardware Types list, select Mouse and click on the Next button. The Manufacturers and Models list appears.
5. From the "Manufacturers and Models" list, click on the Have Disk button.
6. Make sure the Cubix Mouse/Keyboard Multiplexing Software diskette is in the floppy drive, and A:\ WIN95\ is the file path. Click on the OK button.
7. When the Cubix Mouse Driver option appears, select it and click on the Next button.
8. In response to the message "To continue installing the software needed by your hardware, click Finish," click on the Finish button. When the current window closes, the installation is complete and the driver is available for immediate use. Note that rebooting the system is not required.

Windows NT Environment

CBXI8042.SYS is a complete multiplexed mouse and keyboard device driver for Cubix processors running Windows NT. CBXI8042.SYS replaces the I8042PRT.SYS device driver file provided with Windows NT.

To install the Cubix mouse/keyboard driver for Windows NT, run the InstallShield setup program found in the \WINNT subdirectory of the Cubix Mouse/Keyboard Multiplexing Software diskette:

1. Make sure the Cubix Mouse/Keyboard Multiplexing Software diskette is in the floppy drive. From the DOS command prompt of Windows NT, type
   a:\winnt\setup

Follow the prompts provided by the Setup program to install the mouse/keyboard driver.

OS/2 Environment

The Cubix device driver CBXMOUSE.SYS is a fully functional mouse driver that replaces the OS/2 MOUSE.SYS driver. CBXMOUSE.SYS loads PS/2 mouse support whether or not a mouse is physically present.

To install the Cubix mouse driver for OS/2:

1. 1. Copy the file CBXMOUSE.SYS from the \OS2 directory of the Cubix Mouse/Keyboard Multiplexing Software diskette to the \OS2 directory of the boot drive.
2. 2. In the CONFIG.SYS file, remark out the line: device = os2\mouse.sys
3. by placing "REM" in front of it, so that it reads: rem device = os2\mouse.sys
4. 3. In the CONFIG.SYS file, add the line: device = os2\cbxmouse.sys
5. 4. Reboot the Cubix processor to allow the modification in the CONFIG.SYS to take effect.

All Cubix mouse software is designed to be used explicitly with Logitech PS/2 style mice. If non-Logitech mice are to be used then the command line option -nl should be entered in the CONFIG.SYS file following the mouse emulation software filename:

device= cbxmouse -nl

The -nl option disables the synchronizing algorithms specific to Logitech mice. As a result, mouse multiplexing is not supported. However, remote mouse support will still be available.

Mouse/Keyboard Multiplexing Hints

The Cubix mouse drivers are intended for use in Cubix multiplexor subsystems. This section lists some hints for using the mouse/keyboard effectively.

1. Avoid moving the mouse when selecting different channels on the Cubix multiplexor subsystem.
2. When the multiplexor subsystem is powered up, make sure that at least one processor completes the boot process without changing the multiplexor channel.
3. Make sure that the multiplexor channel is enabled while the processor boots so that the mouse will be connected to the processor.
4.
