- An Introduction to X-DOS
- Introduction
-
- X-DOS 5.0 is an enhanced Disk Operating System (DOS) for personal
- computers. It runs on 8088, 8086, 80186, 80286, 80386, i486 and
- compatible microprocessors and supports a wide variety of
- additional hardware. X-DOS is versatile, fast, and user-friendly
- and is designed as a replacement for other disk operating systems
- for personal computers.
- What is a Disk Operating System?
-
- You may be wondering why you need a disk operating system like X-
- DOS 5.0 in the first place. The reason is simple; you will not be
- able to run any existing application programs on your personal
- computer without first loading a disk operating system. The disk
- operating system is the link between the hardware (your computer)
- and the software (any program you may wish to use on your
- computer). Without going into too much detail, disk operating
- systems handle all input and output between the computer, its
- peripheral equipment, and the software program.
- What is Special about X-DOS?
-
- If you have a PC you must already be using a disk operating
- system, so you may well may be wondering why you should switch to
- X-DOS. If you start using X-DOS you will soon find out that there
- are many reasons. X-DOS 5.0 has a user-friendly interface as well
- as an extensive help on all commands, to guide you through the
- initial stages.
- In addition, X-DOS 5.0 includes a number security measures that
- were not previously available at the operating system level.
- These security features include the following:
- * Partition password protection for partitions on hard disks
- with the FDISK command.
- * Management of password protection on partitions with the LOCK
- and UNLOCK commands.
- * Read-Only protection for partitions on hard disks with the
- FDISK command.
- * File encryption with the ENCODE and DECODE commands.
- * The capability to hide files and directories from prying eyes
- with the ATTRIB command.
- * Deletion of files so they cannot be undeleted with the
- WIPEFILE command.
- Besides protecting your data X-DOS also provides utilities to
- ensure the integrity of your data. These features include:
- * Checking of up to 256 files for a possible virus attack with
- the VIRUSCHK command.
- * Making FORMAT perform a SAFE FORMAT of diskettes and hard
- disks so that all data can be recovered from an accidentally
- formatted hard disk.
- * Making CHKDSK perform a surface analysis of a diskette or hard
-

-
- disk to check for bad sectors which may have developed since
- the disk(ette) was formatted.
- * CHKDSK will mark any bad sectors unusable and try to recover
- any data which is located in the same area (cluster) as the
- bad sector.
- * Recovering of accidentally deleted files with the UNDEL
- command.
- In addition to the above mentioned features, X-DOS 5.0 gives you
- many other commands and utilities which are not included in other
- DOSs.
