Multia System Description
Overview
The Multia MultiClient Desktop is a network-ready device that implements the application
server method of client-server computing. The desktop comes with the Windows NT
Workstation operating system and Multia Base Software preinstalled. Alpha- and Intel-based
models are available.
The desktop provides users with access to Windows, Windows NT, and video terminal
applications on host systems and file servers in a variety of network environments. As
options, users can add access to X window applications and mainframe applications.

Troubleshooting
During a normal power-up sequence, the following occurs:
•

The green LED on the power switch at the front of the system box is on.

•

The diagnostic LED between the serial port and twisted-pair connector on the back of the
system box displays a list of sequence codes (page 11).

To address power system problems, you can check the power switch, diagnostic LED, and
power port pinouts. The Power Systems Problems table gives common symptoms of power
problems and recommends actions.

Power System Problems
Symptom

Recommended Action

The power switch LED is off. 1.

Make sure the power switch on the front of the system box is
pushed in.

Make sure the system is plugged in and the power source is
operating. Check the ac cord.

If the switch still does not work, replace the power supply.
(The switch is hardwired to the power supply.)

Initialization and Power-On Self-Test Errors
The diagnostic LED on the back of the system box indicates the symptom of any problem that
occurs during initialization or the power-on self-test (POST).
When you turn on the system, the SROM initializes the CPU, core logic, and memory.
During power-on, the CPU loads the POST from the SROM. Typically, the POST reports
errors that prevent the console from booting.
During power-on, if the system fails a test, the LED flashes to indicate that the test failed. On
the VX40 model, the diagnostic LED also flashes at the beginning of each self-test.

Beep Codes
When POST finds an error and cannot display a message, the computer's speaker emits
a series of beeps to indicate the error and places a value in I/O port 80h. During the
POST, if the video configuration fails or if an external ROM module fails a checksum
test, then your computer beeps three times (one long beep, and two short beeps).
The following table lists other fatal errors and their associated beep codes. Each code
represents the number of short beeps that are grouped together. Fatal errors (errors that
lock up your computer) are generally the result of a failed system board or some other
add-on component (SIMM, BIOS, computer battery, and so forth).
Resolve any problems using the appropriate troubleshooting procedures.

Restoring Multia Software
This chapter describes how to restore the software on a Multia desktop to its initial factory
state. You need the Multia CD-ROM supplied in the System Administrator Kit. The Multia
CD-ROM must be mounted or installed on a system that is network accessible to the desktop
you are restoring. For Intel-based models, you also need the RMF diskette supplied in the kit.
The chapter covers the following topics:
•

Restoring Multia software on a corrupted desktop

•

Setting up servers for the Remote Maintenance Facility

Restoring Multia Software on a Corrupted Desktop
The Multia CD-ROM for system administrators lets you restore the software on a Multia
desktop to its initial factory state. You perform this procedure from the affected desktop.
The repair procedure first downloads Remote Maintenance Facility (RMF) software provided
on the Multia CD-ROM. You must set up MOP or BOOTP and TFTP servers to handle this
process.
Caution
When you restore a desktop to its initial factory state, any user files on the local hard disk
are lost. If you want to save these files, back them up before performing this procedure.
Refer to the section for your Multia desktop model:
•

Intel-based models (page 77)

•

Alpha-based models (page 79)

Restoring Intel-Based Models (Multia Version 3.1)
Prerequisites
•

Intel-based models: Multia Version 3.1 CD-ROM and RMF diskette
Your system administrator's kit provides the CD-ROM and diskette. You need the
diskette the first time you restore a desktop.

•

MOP server or BOOTP and TFTP servers
You can use servers on a host system or Multia-based servers accessible in the
Customize Multia window, Services dialog box. Sample moptab and bootptab files
are in D:\WINNT35\SYSTEM32\DRIVERS\ETC.

To set up a MOP server or BOOTP and TFTP servers, see page 80.
To restore an Intel-based Multia desktop to its initial software state

Multia MultiClient Desktop Service Information

Restoring Multia Software on a Corrupted Desktop

Mount or install the Multia CD-ROM on an accessible host.

Set up the moptab file or bootptab file.
•

For a BOOTP server, specify the correct Multia RMF command file in the
bootptab file (page 82).
Syntax
bf=path\RMFVnnnM.CMD
nnn is the Multia version number. For example, if you have mounted the Multia
Version 3.1 CD-ROM on your E drive, you would specify
bf=E:\V031\files\RMF\RMFV31M.CMD

•

For a Multia MOP server, simply add the location of the Multia CD-ROM's RMF
files to the home directory (HD) in the moptab file (page 81).

•

For an OpenVMS MOP server, add the location of the Multia CD-ROM's RMF
files to the definition of the MOM$SYSTEM logical (page 81).

If you use host-based servers, make sure the servers are running.
If you use Multia servers, start them as follows:
a.

If the Multia CD-ROM is mounted or installed on a remote network drive, use the
Windows NT Control Panel to specify a startup account with administrator privileges
for the MOP or TFTP server (page 83).
You can omit this step if the CD-ROM is on a local drive.

b.
4.

Start the MOP server (page 81) or BOOTP and TFTP servers (page 82) from the
Services dialog box of the Customize Multia window.

Insert the RMF diskette, then restart the desktop. The RMF software prompts you for
•

Whether or not to partition the disk.
If you answer No, the RMF software overwrites existing files on the disk.
If you answer Yes, the RMF software partitions the disk and installs new files. All
existing files on the disk are erased.

•

The network protocol (MOP or BOOTP).

•

The RMF command file name (RMFV31M.CMD for Version 3.1).

When the procedure is complete, the software displays a message telling you to restart
the desktop.
When you restart the desktop, it displays the Multia startup screen. At this point, the desktop
is in its initial factory state. To restore the desktop’s previous configuration, enter the
desktop’s key.
Performing
the RMF
Procedure
Again

When you perform the first RMF procedure on a desktop, the procedure installs the files from
the RMF diskette and adds an RMF menu item to the operating system menu displayed
during the power-up sequence. If you need to perform another RMF procedure on that
desktop, simply stop the power-up sequence when the menu appears and select the RMF
menu item. You do not need the RMF diskette.

Setting Up Servers for the Remote Maintenance Facility
The Multia CD-ROM includes a Remote Maintenance Facility (RMF) that is invoked when
you
•

Perform a Multia software update that includes the operating system

•

Perform a Multia firmware update

•

Restore Multia software to a corrupted desktop

When you select a software or firmware update from the Configuration Manager, the Confirm
Software Update dialog box indicates whether or not the update requires the RMF software.
The automated update or repair procedure first downloads the RMF software from the CDROM kit to the selected desktop. Then the RMF software initializes the desktop’s disk and
downloads the Multia software from the CD-ROM kit to the desktop.
To download the RMF software, you need
•

A maintenance operations protocol (MOP) server, or

•

A boot protocol (BOOTP) server and trivial file transfer protocol (TFTP) server

You can use the servers provided with each desktop or the servers on a host system.
Using the MOP server provided with the desktop can reduce administrative overhead, because
you do not have to maintain a list of client desktops in the moptab file. Since desktops
include built-in support for MOP communication, you can use this approach even in
environments that typically use BOOTP and TFTP servers.
Caution
When you perform major updates involving the operating system, the desktop is restored
to an initial state. Any user files or additional software files installed on the desktop’s
hard disk will be lost. If you want to save these files, back them up before performing
major updates.
Using Multia
Servers

To start Multia servers, you use the Services dialog box in the Customize Multia window.
When you start a MOP or BOOTP server, you specify the network path to the moptab or
bootptab configuration file. For details, see the online help in the Services dialog box.

80 Multia MultiClient Desktop Service Information

Setting Up Servers for the Remote Maintenance Facility

Configuring a Multia MOP Server
If you plan to use a Multia MOP server for updates and repairs, you must set up the moptab
configuration file. Each desktop comes with a sample moptab file in the following location:
D:\WINNT35\SYSTEM32\DRIVERS\ETC\MOPTAB

The moptab file must specify the network path to the home directory (HD) or directories
containing the Multia RMF files to serve for the update or repair. The network path is the
only required information.
The MOP server will service requests from any MOP client for Multia software. The client
request includes a software identification (SI) for the file it is requesting. The MOP server
checks the home directory list for the requested file.
Moptab
Syntax

The moptab file for a Multia MOP server uses the following syntax:
HD=directory1; . . . ;directoryn
HD specifies one or more directories to search for the requested RMF files. The Multia CDROM provides the RMF files in an \RMF subdirectory (Version 3.1 and later) or \EDR
subdirectory (Version 3.0). Separate directories with a semicolon. For example:
HD=D:MULTIA\EDR;F:\KITS\EDR

As an option, you can specify individual clients in the moptab file, along with the file (SI) to
serve each client. This allows the MOP server to serve requests from those clients even when
the request does not specify a file. For details, see the explanation in the sample moptab file
provided with the desktop.
The moptab file must reside in the following location:
D:\WINNT35\SYSTEM32\DRIVERS\ETC\MOPTAB

Configuring an OpenVMS MOP Server
If you use a MOP server on an OpenVMS host system, add the location of the Multia CDROM’s RMF files to the definition of the MOM$SYSTEM logical. Use the DCL DEFINE
command from an account that has system privileges. For example:
$ SHOW LOGICAL MOM$SYSTEM
"MOM$SYSTEM" = "SYS$SYSROOT:[MOM$SYSTEM]"(LNM$SYSTEM_TABLE)
$ DEFINE MOM$SYSTEM SYS$SYSROOT:[MOM$SYSTEM], RMF_directory

RMF_directory is the location of the RMF files. For example, if you installed the RMF files
in SYS$SYSROOT:[MOM$SYSTEM.RMF], you would enter
$ DEFINE MOM$SYSTEM SYS$SYSROOT:[MOM$SYSTEM], -_
_$ SYS$SYSROOT:[MOM$SYSTEM.RMF]

Starting the Multia MOP Server
If you want to use the Multia MOP server, start the server from the Customize Multia
window.
1.

In the Customize Multia window, click the services icon.

In the Services box, select the MOP server.

Enter and save the startup parameters. You have the option to specify the path to the
moptab file. By default, the MOP server uses the following file:
D:\WINNT35\SYSTEM32\DRIVERS\ETC\MOPTAB

Choose Start and Automatic to start the server now and have it automatically start
whenever the desktop is restarted.

For More
Information

See the online help in the Services dialog box.

Configuring a BOOTP Server
If you plan to use a BOOTP server and TFTP server for updates and repairs, you must set up
the bootptab configuration file. Each desktop comes with a sample bootptab file in the
following location:
D:\WINNT35\SYSTEM32\DRIVERS\ETC\BOOTPTAB

The bootptab file must contain an entry for each Multia desktop client to be serviced by the
BOOTP server.
Bootptab
Syntax

For each Multia desktop, add the following entry in the bootptab file. Use a colon to
separate parameters.
Desktop: ht=1: ha=hardware address: ip= IP address: bf=RMF command file

Desktop
Specifies the desktop’s name.
ht=1
Specifies the desktop’s hardware type. This value is always 1 or ethernet.
ha=hardware address
Specifies the desktop’s Ethernet hardware address. You must specify the address in
hexadecimal numbers. You can include optional periods and a leading 0x for readability.
ip=IP address
Specifies the desktop’s IP address. Use standard Internet dot notation, decimal, octal, or
hexadecimal numbers. Octal numbers begin with 0, hexadecimal numbers begin with 0x or
0X.
bf=RMF image file
Specifies the path to an RMF boot file in the Multia CD-ROM kit. The Multia CD-ROM
provides the RMF files in an \RMF subdirectory (Version 3.1 and later) or \EDR subdirectory
(Version 3.0)
•

For Intel-based models
The RMF boot file is RMFVnnnM.CMD, where nnn is the Multia version. For Multia
Version 3.1, the file is RMFV31M.CMD

•

For Alpha-based models
Specify an RMF boot file based on the type of network connection used by your
desktops:
ThinWire or twisted-pair

RMF.SYS

Thickwire

RMFAUI.SYS
