- >>Foreword<<
- ------------
- This story begins with The Boot Factory BBS running
- RemoteAccess v1.11. When I purchased a CD-ROM for my
- BBS, I searched for a program or door to manage the
- file areas and such so that I could run multiple CD's
- on one drive, and still only have the users see the
- files on the currently mounted CD-ROM disk. I
- evaluated several nice programs for this purpose and
- was on the verge of purchasing one when Andrew Milner
- released RemoteAccess v2 with built-in CD-ROM support.
- I realized that with a few little programs I could
- almost completely automate the mounting/dismounting of
- the different disks. I wrote a few programs to manage
- the tough stuff and automated the running of them via a
- simple batch file.
-
- I also found myself telling a LOT of people how to do
- this setup, so I thought I would share the entire
- concept with the rest of the RemoteAccess BBS world -
- hence this document and accompanying files were born.
-
- --------------
- >>Disclaimer<<
- --------------
- Basically this system works extremely well on my
- system, but it is not guaranteed to do anything on your
- system. Cabell Clarke or The Boot Factory BBS assume
- no responsibility for this document. You are on your
- own.
-
- --------------
- >>Principles<<
- --------------
- The problem was "How do I keep users from trying to
- download files from the CD's which were not in the CD-
- ROM drive?" It was immediately apparent that I needed
- a way of only letting them have access to the stuff in
- the drive. In order to set up a single CD system with
- multiple CD's, I determined that I needed to use a
- combination of File Groups, Areas, and Flags to control
- access to the different CD's.
-
- This system uses 2 programs written in Turbo Pascal 7,
- AGSET.EXE and FLAG.EXE which are part of my R_Utils
- package and a controlling batch file, MOUNT.BAT. It
- requires that you set your files groups and areas up in
- a specific way in order for it to work. This document
- will describe how I set my system up. You can either
- set yours up identically, or similarly, or use the
- system as you see fit as long as you understand the
- principles behind it.
-
- This document assumes you already know how to get your
- CD-ROM file descriptions into the RA File Database, so
- we will not cover that here. The steps below will
- outline exactly what I did and hopefully show you how
- to do the same thing or something similar.
-
-
- -------------
- >>Procedure<<
- -------------
- The first step is to assign a unique File Group to each
- CD in my collection. For example I assigned File
- Groups 1, 2 and 3 to "Shareware '93" Volumes 1, 2, and
- 3 ( 3 CD's in this collection). I assigned group 4 to
- "All the files on my Hard Disk", and Group 5 to the CD
- "OffWall Files Vol. 5".
-
- The next step is to assign a unique Flag in
- RemoteAccess to each disk. I have reserved all of the
- 'C' flags for my CDs. As above, the "Shareware 93" and
- "Offwall" CD's are assigned in this order:
-
- CD Flag
- Volume 1 C1
- Volume 2 C2
- Volume 3 C3
- Hard Disk C4
- OffWall C5
-
- The final system setup step is to edit each File group
- and Area, so that the assigned flags are associated
- with the File Group for that CD and the File areas
- found on that CD. All of the areas associated with
- Volume 1 above would have their List and Download C1
- flags set to X (ON). I also set my C1 flag for the File
- Group associated with Volume 1 although you do NOT need
- to use file groups at all if you don't want to.
-
- As you will notice, I can only do 8 CD's using the
- method I have outlined here. If you want to go to a
- little more trouble and set up access bit MASKS with
- your flags, you should be able to mount 255 CD's with 8
- flags (minus 1 for your hard disk areas - 254 maybe).
- Someone correct me if that number is wrong. I haven't
- actually tried it but I'm sure it would work.
-
- -------------
- >>Mount.Bat<<
- -------------
- Finally the Mount.Bat file which automates the mounting
- and dismounting of the CD's. Here it is:
-
- @Echo Off
- if z%1 == z goto Syntax
- if z%2 == z goto Syntax
- agset fg4 fa1
- Flag %1 On
- Flag %2 Off
- Goto Xit
- :Syntax
- cls
- Echo SYNTAX: Mount [OnFlag] [OffFlag]
- :Xit
-
- Let's look at each line individually:
-
- @Echo Off
- Let's turn off screen echo first for cleanliness.
-
-
- if z%1 == z goto Syntax
- if z%2 == z goto Syntax
- These two lines simply check for existence of two
- parameters.
-
- agset fg4 fa1
- This line runs the AGSet program which resets
- every users default file area and group to one that
- always exists on your system - in this case it was
- group 4 and area 1 which reside on my hard disk.
-
- Flag %1 On
- Flag %2 Off
- Finally, the meat and potatoes. We set the flag ON
- (X) (mount) using the first command line parameter and
- the flag OFF (-) (dismount) using the second parameter
- for ALL users.
-
- :Syntax
- cls
- Echo SYNTAX: Mount [OnFlag] [OffFlag]
- :Xit
- And lastly we finish up cleanly with a SYNTAX
- display if necessary.
-
- Plug in the CD that was associated with the Mount flag
- (1st parameter) and away you go. When you remove that
- CD and plug in another simply run Mount.Bat again
- feeding it the appropriate parameters to dismount the
- current one and mount the new one.

- I hope you find this method useful. I do. Please
- consider registering my R_Utils programs for use on
