System Software Restore CD and the System Software Restore/Boot diskette supplied with the computer.
Individual program applications can be re-installed using the Restore Factory Programs selection included
in the “Getting Started” Service selection.
A Windows 95 Backup CD is also included should you choose to install the Windows 95 operating system
only. However, when using only this restore method the computer will not be optimized with the various
utilities and system application software integrated and fully supported by Digital.
Restore All Factory-Installed Software
To restore all factory software proceed as follows:
1) Close and save any open files, close all applicationsand shut down Windows 95.
2) Insert the System Software Restore/Boot diskette into the diskette drive.
3) Insert the System Software Restore CD into the CD-ROM drive.
4) Reboot the computer.
The computer will then prompt for confirmation that you want to perform the software restore
procedure and format the hard disk drive.
5) Enter [Y] to proceed.
The system software isl then copied to the hard disk drive. This process will take about 15 minutes.
6) When the files have been successfully copied, remove the System Software Restore/Boot diskette and
the System Software Restore CD.
7) Reboot the computer.
All system software is now loaded to the out-of-box factory condition.
8) The computer will now display several Windows 95 welcome and user registration screens. Select
“Gathering Information”, then enter any requested user registration and COA license information
requested.
NOTE If the computer can still perform basic functions, Digital recommends to first make
backup diskettes of all important personal files that are created since purchasing the
computer. Restoring the factory software will re-format the hard disk and erase all
personal data.

PHLASH .EXE
Starion computers are equipped with flash memory. This means that users can restore the computer's
BIOS simply by running the PHLASH.EXE utility. Users can also upgrade the computer's BIOS to future
releases by running PHLASH.EXE along with any flash BIOS update diskette if necessary.
Download the PHLASH Utility and any required BIOS update files from the Digital BBS. Afterwards,
PHLASH Utility and BIOS update files can be copied onto diskettes for use. Accessing and using the BBS
is described using the “Getting Started” Services selection or a Digital service representative can help.
The following files should be copied onto the BIOS Diskette:
♦ PHLASH.EXE and associated runtime files.
♦ Binary BIOS images.
Before Using PHLASH.EXE
Before upgrading the BIOS using PHLASH.EXE, make a backup diskette (crisis recovery diskette) of the
old BIOS. It is important to make this diskette. Should you find the BIOS upgrade unsuccessful, this
crisis recovery diskette can be used to return to the old BIOS.
The following is needed to create this diskette:
♦ A blank 3½-inch 1.44 MB formatted diskette.
♦ A diskette copy of the PHLASH Utility downloaded from the Digital BBS.

Utilities & Configuration Digital STARION 9xx & 20xx PC

Creating a Crisis Recovery Diskette
1) Turn on the computer and allow the POST to complete.
If POST detects an error, refer to Chapter 4, “Troubleshooting” to identify and determine how to
correct the problem. After the problem has been resolved, restart the computer.
2) Insert the BIOS diskette into the diskette drive and enter: A:DIR.
The entry should show that the following files are on the diskette:
MINIDOS.SYS
PHLASH.EXE
MAKEBOOT.EXE
MAKECRD.EXE
DEVTBLS.DAT
PHLASH.INI
STARION.ROM
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: C: MD UPGRADE.
4) Copy the files from the 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: A:MD UPGRADE.
7) Return to the hard disk drive and copy the files. From the DOS prompt, enter: C:MAKECRD.
The makecrd 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.

Using a Crisis Recovery Diskette
The crisis recovery diskette must be used only if the computer's BIOS fails or if a BIOS upgrade was
unsuccessful. If the computer's BIOS failed to flash properly or is corrupted in some way, the following
sequence of events occurs:
♦ POST detects an error after a normal boot cycle or a BIOS upgrade. This message appears on the
monitor screen, indicating that the computer's BIOS did not flash properly or has failed.
♦ The BIOS in the bootblock memory automatically executes. The computer attempts to find the
correct BIOS files to execute the correct boot cycle.
♦ The computer beeps several times. This means the computer cannot properly boot using the BIOS
files that were just copied during the flash update.
♦ The computer accesses the diskette drive. The computer is searching for the crisis recovery diskette
to restore the BIOS to its previous known state.
Restore the computer’s BIOS to its previous known state by performing the following procedures:
1) Turn off the computer, unlock and remove the coverand set the recovery jumper (J32) to “Recovery
Mode” (jumper on).
Jumper J32 controls whether the computer is in recovery or normal operation.
2) Replace the cover, insert the crisis recovery diskette into drive Aand 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 cover and set the recovery jumper (J32) to “Normal” (jumper off).
5) Replace and lock the left-side cover and turn the power back on for normal operation.
Upgrading the Computer's BIOS
1) Perform the following steps to update the computer's BIOS in the flash memory to a new updated
one.
2) Locate or create a crisis recovery diskette. (Do not use a crisis recovery diskette created on any other
computer.) Refer to “Creating a Crisis Recovery Diskette”.
Insert the BIOS diskette in the diskette drive.
3) Turn on the computer and allow the POST to complete. The computer now boots from the BIOS
diskette.
If POST detects an error, refer to Chapter 4, “Troubleshooting” to identify and determine how to
correct the problem. After the problem has been resolved, restart the computer.
4) At the MS-DOS prompt, type: A:\UPGRADE\PHLASH.
A screen appears on the monitor warning that the computer's BIOS is about to be erased.
5) Press [Enter] to continue. Press [Esc] to cancel.
If [Enter] is pressed, 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 BIOS diskette.

Configuring the Boot Block Jumper
Perform the following steps to configure the boot block jumper (J32).
1) Turn off power to the computer.
2) Disconnect external devices and power.
3) Unlock and remove the cover.
4) Change the jumper setting of J32 from position 1 - 2 to position 2 - 3.
5) Close the drive bay subassembly.
6) Replace and lock the cover.
7) Reconnect external devices and restore power.
8) Repeat steps 2 - 5 of the BIOS update procedure.
9) Repeat steps 1 - 4 of this procedure.
10) Restore the jumper setting of J32 to position 1 - 2.
11) Repeat steps 6 - 8 of this procedure. The BIOS should now be successfully upgraded.
Utilities and Video Drivers
Setting High Resolution Mode for the Monitor
When purchasing a high resolution monitor, you might want run the Windows 95 Settings program and
access the control panel Display selections to change the monitor type, video resolutionsand color depths
to match the capabilities of the monitor. Refer to “Changing System Setting” section of the Windows 95
manual for more information.
S3refrsh.EXE is an MS-DOS based utility that works in conjunction with Windows 95 Display selections
to set the video controller monitor refresh rates. This utility has been pre-installed and configured at the
factory to meet most monitor resolution needs. In most cases this utility is never needed.
To use S3refrsh.EXE proceed as follow:
1) At the C:\> prompt type: S3refrsh.EXE and then press [Enter].
The S3refrsh utility screen appears.
The refresh options are shown on the left side and the corresponding resolutions are displayed on the
top of the matrix.
2) Click on the desired boxes.
The "X" mark means that a selection is not valid. Selected refresh rates are defined by check marks.
3) Click on EXIT to set the new refresh rate.
The utility will then prompt when wishing to save the changes in the AUTOEXEC.BAT file. Confirm
by entering yes [Y].
