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.

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

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.

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.

Note: The internal cache is internal to the CPU. The external cache operates in Write-Back (WB) Mode if Enable has been selected. The external cache operates in Write-Through (WT) Mode if Enable has been selected. For optimal computer performance, keep this setting at Enabled (WB). The main logic board reserves an area of DRAM for a copy of system BIOS ROM. This DRAM called "shadow memory" is write-protected and has the same addresses as the system BIOS ROM locations. When shadowing system BIOS ROM, the ROM information is copied into an appropriate area in DRAM. This increases the performance because the system BIOS instructions are in fast DRAM instead of ROM. This option enables the system BIOS to be cached in the internal cache and external cache (if installed). This increases computer performance because BIOS instructions can be executed in cache instead of RAM. The main logic board reserves an area of DRAM for a copy of video BIOS ROM. This DRAM called "shadow memory" is write-protected and has the same addresses as the video BIOS ROM locations. When shadowing video BIOS ROM, the ROM information is copied into an appropriate area in DRAM. This increases the performance because the video BIOS instructions are in fast DRAM instead of ROM. This option enables the video BIOS to be cached in the internal cache and external cache (if installed). This increases computer performance as video BIOS instructions can be executed in cache instead of RAM. Allows to enable or disable shadowing of individual segments of ROM to increase computer performance.
Caution: Some option ROMs do not operate properly when shadowed.

Computer Memory Configurations
Adding more memory allows the computer to run larger, more complicated software and to run it faster. The amount of memory the computer supports depends on the type of CPU module that has been installed. When the Pentium PCI Series CPU module has been installed, the computer will support up to 192MB using 32MB SIMMs on SIMM banks 0 through 5. The computer is shipped with at least 8MB of memory. 4MB, 8MB, 16MB, 32MB, or 64MB (future) single in-line memory modules (SIMMs) may be added.
When installing SIMMs take care of the following: SIMMs must be installed in pairs. For example, a 32MB SIMM in bank 0 and a 32MB SIMM in
bank 1. Different SIMM sizes can not be mixed within banks.
SIMMs must be the same type, size, and speed.SIMMs must have an access time of 70 ns or less.
For Celebris XL 6150 Pentium-Pro: Memory must be upgraded in pairs in non-interleaved mode. (Two memory SIMMs of equal
capacity)
Memory must be upgraded in increments of 4 in interleaved mode (Two pairs of equal capacity
SIMMs)
System auto-detects capability to enter interleaved modeSystem auto-detects use of 60 ns memory.Only those configurations listed below are allowedMaximum 192MB

9) If the device is an internal device that has no front panel, replace the plastic filler panel.
10) Replace and lock both side panels.
11) Connect the power cord and monitor cord to the back of the computer. Connect any external devices and plug the power cord into the wall outlet.
12) If necessary, run the BIOS Setup Utility (Setup) to reconfigure the
13) for the new storage drives.
NOTE It isn’t necessary to run Setup when installing a SCSI drive and if the onboard SCSI
controller is already enabled. However, Setup has to be runned if the SCSI controller is disabled or when installing an IDE drive. Refer to
Chapter 2, “Utilities
and Configuration”
for instructions on running the BIOS Setup utility.
5) Insert the new device into the drive bay from the front (Figure 3 - 28).
6) Connect the data cable to the device. The data cable is usually a ribbon cable. Figure 3- 29 shows a cabling configuration using two IDE drives and one diskette drive. Figure 3 - 30 shows a cabling configuration for two SCSI devices.
NOTE Figures 3 - 29 and 3 -30 show sample configurations. Other configurations are
possible. Also, refer to Appendix A for thermal considerations when using disk drives with
high power consumption. Be sure the cable is connected with the correct orientation. Most cables and
sockets are keyed so that they cannot be connected backwards. If the cables or drives are not keyed, pin 1 of the cable has to be connected to pin 1 of the socket.
Pin 1 of the cable is on the edge with the colored stripe. Pin 1 of the socket should be marked number "1" at one end of the socket or with a number "1" printed on the circuit board near one end of the socket.

Chapter 4 Troubleshooting
The following pages provide initial troubleshooting procedures and tables listing specific problems, probable causes, and recommended actions to take if the computer fails after configuring it or after installing optional hardware or software. Refer to the documentation supplied with additional options when experiencing problems with specific options that have been installed.
Initial Troubleshooting
Follow the general procedure below to troubleshoot the CELEBRIS XL computer series:
1) Press [Ctrl] + [Alt] + [Del]. If the computer fails to boot, turn it off, wait until all hard disk drives
are spun down completely and then turn it back on.
2) If the 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.
3) Run the BIOS Setup utility.
4) Make sure all necessary changes have been made to the CONFIG.SYS and AUTOEXEC.BAT files.
5) Make sure all necessary video, printer, and application device drivers are properly installed.
6) Ensure that all cables and connections are secure.
7) Run the QAPLUS/fe advanced diagnostic software.
8) If these steps do not identify and/or correct the problem, perform the specific troubleshooting procedures appropriate to the circumstances.
NOTE If you need to return a failed component, pack it in its original container and return it
to Digital for service.
Fill in the appropriate fields of the Part Exchange Form with the relevant error information!!

POST and Boot Messages
The POST displays messages to alert to errors in hardware, software, and firmware or to provide operating information about the computer. Each time the POST displays a message on screen, the computer’s speaker beeps twice. If an error occurs before the monitor is initialized, specific beep codes sound to alert to a problem.
POST and Boot Error Messages
The following error messages are arranged in alphabetical order.
NOTE
Italics
indicate variable parts of a message such as memory addresses hexadecimal
values and so on. These messages can differ at each occurrence.
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. During POST, if the video configuration fails or if an external ROM module fails a checksum test, then the 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 the computer) are generally the result of a failed main logic board or some other add-on component (SIMM, BIOS, computer battery, etc.).
Each code represents the number of short beeps that are grouped together.

Digital CELEBRIS XL & XLDP PC Device Mapping
Chapter 5 Device Mapping
This section provides a series of tables listing mapping and address information related to computer memory and various main logic board devices (keyboard controller, interrupt controller, DMA controller, etc.). The memory and address locations are allocated at the factory to operate within a standard PC environment. However, due to the number of optional devices and/or expansion boards that are available, sometimes memory and address locations need to be changed. For example, some network expansion boards require a specific memory location. If that location is already allocated, a memory conflict results and the expansion board will not operate as expected. Note that some memory, I/O and interrupt locations can be changed using the BIOS Setup utility.
CAUTION Before changing any memory or address location, refer to the documentation supplied
with the optional device, expansion board, or software application and make sure adequate information is available.
