Restoring Win95 Factory-Installed Software

To restore all factory-installed software, proceed as follows:

1) With the computer off, put the WIN 95 Companion CD into the CD drive.

2) Insert the CELEBRIS XL Win 95 Setup/Restore diskette into the diskette drive.

3) Turn the computer on.
The computer boots automatically from the diskette and prompts for confirmation.

4) Enter [Y] to proceed and the system software will then be copied to the hard disk drive.

5) When prompted to do so, insert the CELEBRIS XL Win 95 Setup/Restore diskette into the CD drive,
which will load the Getting Started and related help files and utilities.

6) When the files have been successfully copied, remove the boot diskette and the CD ROM.

7) Reboot the computer.
All system software is now loaded to the out-of-box factory condition.

NOTE If the computer can still perform basic functions, we recommend that the customer

makes backup diskettes of all important personal files. Restoring all factory­installed software will re-format the hard disk and erase all files.

Restoring WFW Factory-Installed Software

For Windows for Workgroups, run Make Media Master to create backup operating system and
utilities/drivers diskettes.
The Make Media Master program prompts to place diskettes in drive A and then automatically copies the
files to drive A.

To restore all factory-installed software, proceed as follows:

1) With the computer off, put disk 1 for the DOS setup into the diskette drive.

2) Turn the computer on. The computer will boot automatically from the diskette and prompts to install
the other diskettes.

3) When the files have been successfully copied, remove the boot diskette.

4) Reboot the computer.
All system software is now loaded to the out-of-box factory condition.

NOTE If the computer can still perform basic functions, we recommend that the customer

makes backup diskettes of all important personal files. Restoring all factory­installed software will re-format the hard disk and erase all files.

Restoring Windows NT Factory-Installed Software

To restore all factory-installed software, proceed as follows:

1) With the computer off, put the Windows NT OS CD into the CD drive.

2) Insert disk 1 of the Windows NT Setup diskettes into the diskette drive.

3) Turn the computer on.
The computer boots automatically from the diskette and prompts when to insert the other setup

diskettes. Follow the instructions in the Windows NT manual.

4) When prompted to do so, insert the CELEBRIS XL Software Restore CD into the CD drive, which
will load the related help files.

5) When the files have been successfully copied, remove the boot diskette and the CD ROM.

6) Reboot the computer.
All system software is now loaded to the out-of-box factory condition.

NOTE If the computer can still perform basic functions, we recommend that the customer

makes backup diskettes of all important personal files. Restoring all factory­installed software will re-format the hard disk and erase all files.

Using System Utilities

These utilities enable to upgrade or restore the BIOS and set the parallel port to EPP mode (only if the
printer supports EPP mode). If this is the first time using these utility programs, it is recommended to
follow the procedures in the order given.

1) Turn on or reboot the computer. If POST detects an error, refer to Chapter 4,“Troubleshooting” for
possible causes and suggested solutions.

2) If necessary, run PHLASH.EXE to restore or upgrade the BIOS to a new one provided.

3) Run EPP3NS.EXE to configure the computer for EPP operation.

PHLASH.EXE

All computers have BIOS software on a chip on the main logic board. This BIOS initializes hardware and
boots the operating system when the computer is turned on. The BIOS also provides access to other
services such as keyboard and disk drives.
The computer comes equipped with flash memory. This means that the BIOS can simply be restored by
running the PHLASH.EXE utility. The BIOS can also be upgraded to future releases by running
PHLASH.EXE along with any flash BIOS update diskette if necessary.

Utilities & C onfiguration Digital C ELEBRIS XL & XLDP PC

18 M C S Logistics Engineering - Nijm egen

Before Using PHLASH.EXE

Before using PHLASH.EXE to upgrade the BIOS, create a crisis recovery diskette. This diskette can than
be used to reprogram the BIOS in case the flash process built into the computer fails.

Have the following items available:

♦ A blank 3½-inch 1.44MB formatted diskette
♦ A diskette copy of the multilingual BIOS upgrade diskette

Creating a Crisis Recovery Diskette

To create a crisis recovery diskette:

1) Turn on the computer and allow the POST to complete.

2) If POST detects an error refer to Chapter 4, “Troubleshooting” and take the appropriate steps to

correct the problem. After the problem has been resolved, restart the computer.

Insert the multilingual BIOS diskette into the diskette drive and enter:

a:dir

The entry should show the following files are on the diskette:

MINIDOS.SYS
PHLASH.EXE
MAKEBOOT.EXE
MAKECRD.EXE

Note that there are some additional files as well. Refer to the README file on the diskette for

additional information.

3) Create an upgrade directory on the hard disk drive. For example, if the hard disk drive is c:>, enter at
the DOS prompt: md upgrade.

4) Copy the files from the multilingual BIOS diskette into the upgrade directory on the hard disk drive.
For example, from the DOS prompt enter: copy a:\upgrade\*.* c:\upgrade\*.* .

5) Insert a blank formatted diskette into drive A.

6) On drive A, make a directory for the files previously copied. For example, from the DOS prompt
enter:

md ugrade.

7) Return to the hard disk drive and copy the files. From the DOS prompt enter: makecrd.

The

QEOIGVH

command prompts for a recovery diskette to be placed in drive A and then

automatically copies the files to drive A.

8) Remove the crisis recovery diskette from drive A and store it in a safe place.

PC Utilities & Configuration

MCS Logistics Engineering - Nijmegen 19

Using the Crisis Recovery Diskette

The crisis recovery diskette must be used only if the BIOS fails or if a BIOS upgrade was unsuccessful.
If the BIOS failed to flash properly or is corrupted in some way, the following sequence of events occur:

1) POST detects an error after a normal boot cycle or a BIOS upgrade.
Messages appear on the monitor screen to inform that the BIOS did not flash properly or has failed.

2) The BIOS in the bootblock memory automatically executes.

3) The computer attempts to find the correct BIOS files to execute the correct boot cycle.

4) The computer beeps several times.
This means the computer cannot properly boot using the BIOS files that were just copied during the

flash update.

5) The diskette drive begins searching for the crisis recovery diskette to restore the BIOS to its previous
known state.

Restore the BIOS to its previous known state by performing the following procedures:

1) Turn off the computer, unlock and remove the left-side cover, and set the recovery jumper (J34) to
enabled. Also, make sure that J35 is enabled.

Jumper J34 controls whether the computer is in recovery (Enabled) or normal (Disabled) operation.

Jumper J35 allows for (Enabled) or prevents (Disabled) flashing of the BIOS.

2) Replace the left-side cover, insert the crisis recovery diskette into drive A, and then power on the
computer.

The computer automatically boots from drive A and upgrades the BIOS. Upon completion, the

computer sounds a beep code and attempts to restart.

3) After the BIOS is restarted, turn off power to the computer and remove the crisis recovery diskette
from drive A.

4) Remove the left-side cover and set the recovery jumper (J34) to disabled.

5) Replace and lock the left-side cover and turn the power back on for normal operation.

Upgrading The BIOS

Perform the following steps to update the BIOS in flash memory:

1) Create a crisis recovery diskette if not already done so.

2) Insert the multilingual BIOS diskette in the diskette drive.

3) Turn on the computer and allow the POST to complete.

The computer now boots from the multilingual BIOS diskette.
If POST detects an error refer to Chapter 4, “Troubleshooting” and take the appropriate steps to

correct the problem. After the problem has been resolved, restart the computer.

4) At the MS-DOS prompt, type: \upgrade\phlash

A screen appears on the monitor warning that you are about to erase the computer’s BIOS.

5) Press [Enter] to continue. Else, press [Esc] to cancel.

When pressing [Enter], PHLASH.EXE automatically updates the computer’s BIOS.
After the flashing process completes, the computer automatically reboots itself so changes

immediately take effect.

6) Remove the multilingual BIOS diskette.

Perform the following steps to upgrade the BIOS to a new language:

1) Turn on the computer and allow POST to complete.
If POST detects an error refer to Chapter 4, “Troubleshooting” and take the appropriate steps to

correct the problem. After the problem has been resolved, restart the computer.

2) Insert the multilingual BIOS diskette into drive A.

3) At the DOS prompt, type: \phlash**
where ** represents the appropriate BIOS language as follows:
GR German
FR French
IT Italian
EN English
For example, to switch to a Spanish BIOS enter: \phlashSP
A screen appears on the monitor warning that you are about to erase the BIOS.

4) Press [Enter] to continue. Else, press [Esc] to cancel.
When pressing [Enter], PHLASH.EXE automatically updates the BIOS.
After the flashing process completes, the computer automatically reboots itself so changes

immediately take effect.

5) Remove the multilingual BIOS diskette.

Using EPP3NS.EXE to Configure an EPP Parallel Port

EPP3NS.EXE is a device driver for configuring the parallel port as an enhanced parallel port (EPP).
Before loading this device driver, check the documentation for the device to be connected to the parallel
port and make sure it supports EPP mode. If it does not, there is no need to load this device driver.

If the device does support EPP mode, perform the following:

1) Either copy EPP3NS.EXE to the hard disk drive or locate it on the hard disk drive’s factory installed

software (Note the path where the driver is located).

2) Edit the CONFIG.SYS file to enter the path for EPP3NS.EXE.
Refer to the DOS documentation for information on editing the CONFIG.SYS file. For example a

line in the CONFIG.SYS might be: device=C:\epp3ns.exe

3) Save the new version of the CONFIG.SYS file.

4) Press [Ctrl] + [Alt] + [Del] to reboot the computer.

5) Before POST completes, press [F2] to enter Setup.

6) Choose the Advanced Menu in Setup and select Parallel Port Mode.

7) Choose EPP mode.

8) Select Save Changes and Exit to save the new setting.
The computer will then automatically reboot.

The parallel port is now configured as an EPP port.
