- A. Installation Notes
-
- Although System Commander itself only takes a few minutes to
- install, a number of very important decisions must be made.
-
- Even if you're an expert and never look at manuals, we strongly
- suggest reading chapter 3, and following those instructions.
- Almost all reported problems have resulted from not reading or
- following the instructions in this critical Chapter.
-
- Additional Notes not in the manual:
-
- Multiple Primary DOS Partitions
- Unix System V
- Disk Error Message after OS Selection
-
-
- Multiple Primary DOS Partitions
-
- Although extremely rare, it is possible to have a system with
- more than one DOS primary partition on the first drive. DOS by
- itself (and DOS's FDISK) will NEVER create such a configuration.
- If additional drives are necessary, FDISK will only allow one
- primary DOS partition, but makes no restrictions on the number
- of DOS logical partitions.
-
- System Commander is designed to work on systems with multiple
- DOS partitions, even if the bootable DOS partition is not the
- first primary DOS partition. For example, a system has OS/2
- version 1.x installed (which always uses a DOS partition).
- Later DOS is installed into another primary partition by using
- OS/2's FDISK.
-
- When installing System Commander on such a system, you must boot
- up from the hard disk under DOS (i.e. not OS/2). To do this, use
- FDISK or the SCDISK utility included on the System Commander
- diskette to mark the DOS partition that holds DOS as bootable,
- and reboot.
-
- Once DOS is running, install System Commander. System Commander
- will automatically detect the unusual configuration. If it has
- any problems with the configuration (like no partitions marked
- bootable), System Commander will notify you, and exit before
- completing the installation.
-
- Unix System V
-
- Most operating systems expect to see a single partition bootable,
- with all other primary partitions marked as non-bootable. Unix
- System V requires all System V partitions be marked as bootable,
- even if the partition is not truly bootable. Bootable status is
- often referred to as the "active partition" by FDISK.
-
- A new option was added to the local options menu, under setup,
- to override the default operation. The new option is
- "Bootable/active status across partitions". If using Unix
- System V, set this option to OVERRIDE ON. All other operating
- systems, including other Unix variants, should use the default
- setting of AUTO.
-
- Disk Error Message after OS Selection
-
- If you have non-standard hard drives which cannot be properly
- accessed without a special device driver, System Commander may
- not be able to update partition information on that drive.
- IDE, ESDI, MFM, and SCSI drives do not usually fall into this
- category.
-
- For example, some hardcards remain in a read-only mode until
- their device driver runs. These types of drives are usually
- limited to DOS, since device drivers are rarely available for
- other operating systems.
-
- It is safe to select "Continue" instead of the recommended
- "Reboot" from the disk error warning message. To eliminate the
- problem (without replacing the drive), from the OS selection
- menu, select F2-Setup, then "Global special options menu".
- Select the choice "Disk drives, above drive 0, ignored". If
- the problem drive is the third drive, select 2. If the drive
- is the second drive, select 1 & 2. This option forces
- System Commander to ignore the specified drives. Drive 0
- must always be accessable.
-
-
- B. Disk Compression
-
- We do not recommend using System Commander with disk compression.
- Although it is possible to do so, the disk compression program
- can cause problems when different DOS versions are run. In
- addition, System Commander itself must operate before the disk
- compression software runs. Drive swapping can cause compression
- or misplacement of the System Commander files. In all, there
- may be a number of problems and you are ON YOUR OWN should you
- attempt this!
-
- If you attempt to install System Commander on a system using disk
- compression, you MUST know which drive is the non-compressed boot
- drive. This is often hidden by the disk compression. For
- example, on two systems using Microsoft's DoubleSpace disk
- compression, one uses drive D, and another uses drive H as the
- non-compressed boot disk. It is rarely drive C:. Perform a DIR
- command from each root directory to help locate which drive is
- the non-compressed boot drive. The boot drive usually has
- a few files. One file, usually marked as hidden, is used for
- disk compression and will be huge.
-
- After the System Commander installation, when you reboot, should
- you get an "Boot Err n, Hit key." message, it indicates either
- you selected the wrong drive to install System Commander and/or
- the disk compression method prevents access to System
- Commander's files. Refer to Chapter 6, Troubleshooting for
- notes on restoring the system to normal. DO NOT go in and delete
- System Commander files, one file holds the original master boot
- record, needed to restore the system to normal.
-
-
- C. Features
-
- With System Commander you'll be able to have multiple operating
- systems function on a single PC. Once installed, when you boot
- up, you will be provided with a menu of OS choices, based on the
- operating systems you install.

-
- D. Problems
-
- Most problems are easily resolved as described in the manual
- under Chapter 6, Troubleshooting.
-
- System Commander's installation always provides an Uninstall
- option, available from the hard disk or the diskette. Refer
- to the Uninstallation instructions, should you need to do
- this.
-
- Boot Err 2 - Hit Key
-
- If immediately after installation the "Boot Err 2" message
- appears, see Chapter 6, Troubleshooting for reasons why this
- might occur and how to correct for it.
-
- One reason this can occur is if you simply copy the files from
- the installation floppy to the hard disk. You MUST install
- System Commander from the diskette so it's files are properly
- placed on the hard disk and uninstall information is saved onto
- the diskette.
-
-
- E. Technical Support
-
- If you followed the steps in Chapters 3 and 4, you are unlikely
- to have any problems. Chapter 6, Troubleshooting covers some of
- the rare problems which might be encountered. Seemingly bad
- problems like "Invalid COMMAND.COM" are usually solved easily,
- and are described in Chapter 6.
-
- Technical support is available to registered users for 90 days
- after purchase. If you call after this period, please have a
- credit card ready for a nominal charge per call. All technical
- support calls require your serial number and version number,
- which is found on your diskette label.
