PHLASH.EXE
All VENTURIS Pentium computers have BIOS software in a read-only, non-volatile memory (ROM) chip.
The BIOS initializes hardware and boots the operating system when the computer is switched on. The
BIOS also provides access to other devices such as keyboard and disk drives.
The computer comes equipped with flash memory. This means that the computer's BIOS can be restored
simply by running the PHLASH.EXE utility contained on the supplied System Utilities diskette. The
computer's BIOS can also be upgraded to future releases by running PHLASH.EXE along with any flash
BIOS update diskette, if necessary.
CAUTION
When not familiar with utility programs and their uses, carefully read and understand
all of the listed topics before attempting to use PHLASH.EXE.
Have the following items available:
♦ Blank 3½-inch 1.44 MB formatted diskette
♦ Diskette copy of the system utilities
Creating a Crisis Recovery Diskette
A crisis recovery diskette should always be prepared before attempting to upgrade the BIOS. This diskette
is used to reprogram the BIOS in case the flash process fails. To create a crisis recovery diskette:
1) Turn on the computer and allow the POST to complete. If POST detects an error refer to
“Troubleshooting” and take the appropriate steps to correct the problem. After the problem has been
resolved, restart the computer.
2) Insert the system utilities diskette you created from Getting Started and make sure the following files
are in the UPGRADE directory:
MINIDOS.SYS
PHLASH.EXE
DEVTBLS.DAT
PHLASH.INI
VENTURIS.ROM
MAKEBOOT.EXE
MAKECRD.EXE
NOTE
This diskette also contains multilingual BIOS files that can be used to change the
language type in Setup.
3) Create the same directory on the hard disk drive and then copy the above files to it.
4) Insert a blank formatted diskette into drive A.
5) On drive A, make a directory for the files previously copied.
6) From drive C: type MAKECRD. This copies the files to drive A.
7) Remove the crisis recovery diskette from drive A and store it in a safe place.

Digital VENTURIS Pentium PC Utilities & Configuration
MCS Logistics Engineering - Nijmegen 17
Using the Crisis Recovery Diskette
The crisis recovery diskette must be used only if the computer's BIOS fails or if a BIOS upgrade was
unsuccessful.
♦ POST detects an error after a normal boot cycle or a BIOS upgrade.
♦ The BIOS in the bootblock memory executes.
♦ The computer beeps several times.
♦ The diskette drive begins searching for the crisis recovery diskette.
If the computer's BIOS fails:
1) Set the recovery jumper (J25 on VENTURIS 560 models, J10 on the other VENTURIS Pentium
models ) to enabled.
2) Insert the crisis recovery diskette into drive A and power on the computer.
3) After the BIOS is restarted, turn off the power and remove the crisis recovery diskette from drive A.
4) Turn the power back on for normal operation.
