- How to put more than 20 CDROM disks on line when you only have 26 drive
- letters under DOS...
-
- Since I haven't seen the solution anywhere despite quite a number of inquiries
- and since numerous Tech Support departments couldn't help, here goes.
-
- Problem: Since each CDROM disks consumes a drive letter, and since most
- people remap local drives to other drive letters, when you get above about 12-
- 15 CDROM disks on line you start wishing DOS supported more than 26 drive
- letters.
-
- There are 2 solutions. The first are programs that support the XDISC Pioneer
- program for Pioneer minichangers. That is workable, I believe but it requires
- 3rd party software use and means the caller must exit via a door losing the
- familiar PCBoard interface. It also means PCBoards lose ROBOCOMM
- compatibility for disks accessed in this manner. Also this leaves out the
- people who shun the minichangers in favor of individual drives. Still, you'll
- be able to get up to 90 disks on line with 15 drive letters using minchangers.
-
- Another way is to use a computer as dedicated a CDROM server. I'm using
- Lantastic. If you boot from floppies (no hard disk), you'll have 24 available
- drive letters on that computer. You can on put 4 minchangers for 24 CDROM
- disks or if you prefer standalone 1 disk units, you'll still be able to put
- 24 disks on. You'll use drive letters C: through Z: on that machine. We'll
- call this server \\ROM1.
-
- On the other computers in the LAN, you log into \\ROM1, then use the command
- NET USE Z: \\ROM1
- This maps ALL drives in \\ROM1 to Z: on the local machine. Z:\C through
- Z:\Z become the CDROM disks, each in a subdirectory under the drive letter Z:.
- PCBoard's indexing utilities have no trouble indexing these disks this way.
- You can put a second CDROM server on line, again with no hard disk and with
- 24 CDROM disks using a second drive letter, Y:, and a third using X:, etc.
- Using 3 computers as ROM servers, we've mapped in 72 disks using only 3
- network drive letters.
-
- It isn't cheap but there is no longer a 15 or so disk ceiling. Using your
- original 15 drive letters, you could put 360 CDROM disks on line this way. If
- this isn't enough, I believe it may be possible to to use a second line of
- computers as CDROM hub's, each serving 24 CDROM servers, getting you up to
- 8640 disks in 8640 conferences, again, just using 15 drive letters. This way,
- each CDROM disk can be in its own conference, no doors are needed, no external
- protocols are used, and the board stays fully PCBoard compiant including
- Robocomm compatibility for all disks.
-
- Getting back to solution 1, using Xdisk supporting 3rd party programs, it may
- be possible to map each 6 disk minichanger into a drive letter on the server
- allowing up to 24 changers on 1 CDROM server or 144 CDROM disks on 1 CDROM
- server using 1 drive letter on the network.
