PTSCDEX.COM Driver

Purpose: File system support for CD-ROM disks (ISO9669) in presence of
         hardware driver.

Syntax:  [drive:][path]PTSCDEX.COM [/D:driver] ... [/L:letter] [/C:size]

Description:

     This driver is used to access to files stored at CD-ROM disks.
     Typical usage of the driver in CONFIG.SYS is the following:

        DEVICEHIGH  = C:\CD\ATAPICD.SYS /D:PTSCD001
        INSTALLHIGH = C:\PTSDOS\PTSCDEX.COM /D:PTSCD001 /L:S /C:2048

usually supported with CD-ROM drive) with PTSCD001 name.  The second one
installs CD-ROM file system support.

           be arbitrary but the same as the name of the hardware driver).

           hardware driver.
