CDROMS

By default our NETUNITS.SYS driver will allocate all drives through Z to the network, so no drive letter is available to the CDROM driver (MSCDEX.EXE) when it attempts to load. If you own LBL version 2.0g or later you do not have to load NETUNITS.SYS. Simply remove it from CONFIG.SYS or REM it out. But if you do this, make sure LASTDRIVE is set at least as high as the greatest network drive letter.

Another method of solving the cdrom problem is taken care of by our CDROM utility. (located in C:\LBL\UTILS). This utility tells DOS and LBL which drive letter should be made available for the CDROM. This method must be used for earlier versions of LBL.

If you want your CDROM to appear as drive S: then put into your AUTOEXEC.BAT file prior to the CDROM extensions: 

        C:\LBL\UTILS\CDROM S:
This will make drive S: available to the CDROM driver when it loads. If you do not do this then you will get an error message from the CDROM driver saying there are not any drive letters remaining, therefore it will not load. Here is a setup example: 
        CONFIG.SYS:

        DEVICE=\CDROM\MTMCDS.SYS /D:MSCD001 /P:300 /A:0
        DEVICE=\LBL\NETBSHAR.SYS LPT1 LPT1 ON:0 OFF
        DEVICE=\LBL\NETUNITS.SYS
        DEVICE=\LBL\NET00000.SYS #45 "CDROM 286"

        AUTOEXEC.BAT:

        \LBL\UTILS\CDROM S:
        \CDROM\MSCDEX.EXE  /D:MSCD001
        \LBL\NET8
        \LBL\ARC_LINK INT13
        \LBL\NET21
A third method of installing a CDROM requires limiting the number of units allocated by NETUNITS. You must use the @n parameter on the NETUNITS line --"n" should be a number at least 1 less than the number of free drives before LBL is installed. This number can be found by running the NODE utility. Look for the number of added LBL drives indicated by "LBL added drive count = n" report. Subtract 1 from this number and put this on the NETUNITS line and tell DOS to reserve drive Z. Then you must run LBL.COM and redirect drive Z to be on the local node's drive Z, ie, to itself.

If, for example, you have physical drives A,B, and C, then an @4 on the end of the NETUNITS.SYS line will add LBL "networkable" drives D,E,F, and G -- that is, four more letters. Then your cdrom would automatically use drive letter H which is the next available letter.
