Configuration - Hard Drive

SYSTEM BOARD SETTINGS

Hard Drive configuration is accomplished using the disk-based SETUP programs .There are no user-configurable jumpers or switches on the system board.

HARD DRIVE JUMPER SETTINGS

Compaq does not support more than one hard drive at a time in the Deskpro XE systems. Therefore we offer no jumper settings for Master-Slave setups.


Configuration - System

486 Based Systems.

Switch SW500 is a four-position switch that indicates the type and frequency of the installed microprocessor.  When the computer is upgraded with a new processor or coprocessor, the settings for Switch SW500 must be changed.

80/120 Megabyte Tape Drive

COMPAQ Diagnostics Version 6.21 or Version 7.01 (or later) is required for

installing the 80/120 Megabyte Tape Drive.

SY-TOS Tape Backup and Restore Utility

  The SY-TOS tape backup and restore utility is supported by MS-DOS as published by Compaq as well as by MS OS/2 Standard Version 1.1 (or later) as published by Compaq.  The utility comes with the tape option kit and includes the hardware, software, and documentation.

  The 150/250 Megabyte Tape Drive option includes Sytos Plus File Backup Manager, which is supported by MS-DOS Version 3.0 (or later) as published by Compaq or MS OS/2 Version 1.2 (or later) as published by Compaq.

320/525 Megabyte Tape Drive or 1.3/2.0 Gigabyte Digital Audio Tape Drive (DAT) Sytos Plus File Backup Manager supports the new tape drive operating under MS-DOS Version 3.0 (or later) or MS OS/2 Version 1.2 (or later) as published by Compaq.

CAUTION

MS-DOS tape backups created with SY-TOS can be read from but not written to when using the Sytos Plus version.  Using Sytos Plus to write to a tape created by SY-TOS corrupts all data on the tape.  When writing to an existing tape with Sytos Plus, restore the tape to a fixed disk drive, format the tape with Sytos Plus, and back up the data again.

  SY-TOS cannot read or write tape backups created by Sytos Plus under the

Sytos Plus format.  SY-TOS can read tape backups created by Sytos Plus under the SY-TOS format.

IMPORTANT: MS OS/2 tape backups, created with earlier versions of MS OS/2 and SY-TOS, can be read by Sytos Plus and MS OS/2 Standard Version 1.2.
