-
-
- This program is intended to ensure the integrity of the system built by
- DISK MANAGER. Specifically, DISK MANAGER requires two things in order to
- properly operate in the system of your computer. If these two prerequisites
- are not met, you will experience an error SIMILAR to the following when
- attempting to access a partition which DISK MANAGER has placed on your disk:
-
- INVALID DRIVE SPECIFICATION
-
- If you do not experience this type of error message, DMCFIG will not be
- helpful to you.
-
- DISK MANAGER allows the use of large and nonstandard disk drives through a
- device driver. This device driver makes the partitions that DISK MANAGER
- creates as types "WRITE-READ" and "READ-ONLY" useable to your system as
- individual DRIVE-LETTERS (C:, D:, etc.).
-
- Our device driver is named "DMDRVR.BIN". The following rules MUST be
- satisfied to see that it gets installed when your system boots:
-
- 1) The file "DMDRVR.BIN" must be on the boot device
- 2) A file "CONFIG.SYS" must be on the boot device, and
- it MUST reference the DMDRVR.BIN file.
-
- a) As a minimum, we require a statement to read
-
- "device = dmdrvr.bin"
-
- to appear in CONFIG.SYS.
-
- b) Other "device =" statements may also appear if desired.
-
- c) For more detailed information on CONFIG.SYS, see your DOS
- manual.

-
-
- Normally, when DISK MANAGER creates a BOOTABLE DOS PARTITION on the disk,
- it automatically sets that partition up in such a fashion as to cause the
- device driver to load properly. There are, however, several circumstances
- which could cause the device driver to become "configured-out" of the system:
-
-
- 1) Installation of some applications will alter the CONFIG.SYS file
- and delete the reference to our driver.
-
- 2) Use of the DOS "format" command on the DOS partition will clear
- our driver file and the config.sys file.
-
- 3) Use of the DOS (or other backup means) RESTORE process which
- changes the contents of CONFIG.SYS.
-
- 4) Inadvertently deleting or erasing either CONFIG.SYS or our
- driver file.
-
- 5) Installing a second physical disk, when the first was already
- installed, but NOT by DISK MANAGER.
-
- Fortunately, DATA IS NEVER LOST from the driven partitions when these
- situations occur. The data is temporarily inaccessible, but it remains
- intact.
-
-
- DMCFIG can be invoked from the "A>" prompt with the DISK MANAGER diskette
- in the A: drive. By default, it assumes you will be booting off of the C:
- drive, which is normally the first NON-FLOPPY drive in the system.
-
- Invoke DMCFIG as follows:
-
- A>DMCFIG<ENTER> to maintain the C: drive
-
- or, alternatively,
-
- A>DMCFIG D:<ENTER> to maintain the D: drive (substitute any
- valid drive-letter)
-
-
- DMCFIG will perform the following actions:
-
-
- 1) Verify the existence of CONFIG.SYS on the given drive-letter.
-
- If it is not found, it will be created with an appropriate reference
- to our device driver.
-
- If it is found, it will be examined for the presence of a line which
- invokes our device driver. If it does not find one, an appropriate
- line WILL BE ADDED at the beginning of CONFIG.SYS.
-
- DMCFIG will notify the operator of any action it takes.

-
-
- 2) Verify the existence of DMDRVR.BIN on the given drive-letter.
-
- If it is not found, a message is issued which indicates it was not
- present, and instructions are displayed on how to get it out there.
- Specifically, you must COPY it from the DISK MANAGER diskette.
-
- Example: A>COPY DMDRVR.BIN C:
-
- This example assumes the DISK MANAGER diskette is in A:, and
- that your target boot disk is C:.
-
- If it is found, you will be notified accordingly.
-
-
- 3) DMCFIG will then terminate.
-
-
-
- Please note that you are free to modify CONFIG.SYS to perform this or
- other functions with your favorite word processor, or EDLIN, or COPY CON,
- etc. We believe DISK MANAGER to be fully compatible with all other
- well-behaved device drivers and applications.
-
- As long as the appropriate CONFIG.SYS and DMDRVR.BIN files exist on
- your boot device, you should see the DISK MANAGER sign-on banner when you
- boot the system, and the driven partitions should be valid drive-letters.
-
- If this still does not occur, there are probably NO "WRITE-READ" or "READ-ONLY"
- DISK MANAGER partitions on your disk. You may use "DM /M" (DISK MANAGER in
- MANUAL MODE) to inspect the PARTITION TABLE to see if this is the case.
