Configuration of Media Vision CD-ROM/Sound Card T3100 AST for Tandy System
Sold by Computer City.  This kit was also used on certain configurations
of Tandy Omni II MT Servers by AST and Tandy Omni Profile II machines by
AST.

This particular upgrade kit consisted of:

    CDR-H93RSA          SCSI CD-ROM drive
    Media Vision sound card (no special identification)

Checked setup for the OMNI Profile II system (259-7710) and disabled the
printer port to free up IRQ5 and IRQ7.

Installation of the CD-ROM was standard with adding the CD-ROM drive in
the 5.25" drive bay, adding the interface card jumpered to the default
settings, and running the cables between the two boards (the audio cable
and the SCSI interface cable).  Interface card and CD-ROM drive logic
board are clearly marked which pin is PIN 1.  Cable is keyed for insertion
on the interface card, but not on the CD-ROM logic board.

Included is a PAS 16 SCSI Installation Disk.  The INSTALL procedure
configures a default system as follows:

    DMA                           5
    IRQ                           7
    Joystick Enable               Yes
    Sound Blaster emulation       Yes
        I/O Address               220H
        IRQ                       5
        DMA                       1
    MPU 401 emulation             No
    Modify C:\DOS System files    Yes
    Modify Windows System files   Yes

Once the installation is complete, you can then check in Control Panel to
locate the following driver options:

    Spectrum Sound Mixer Driver
    Spectrum Sound Wave/MIDI/Aux

When the system boots up, the message displayed is that the SCSI host
adapter for the CD-ROM drive is detected at port 388H.

The following entries are added to the boot files:

    CONFIG.SYS

    device=c:\spectrum\mvsound.sys d:5 q:7 S:1,220,1,5 m:0 j:1
    device=c:\spectrum\tslcdr.sys /d:mvcd001 /R

    AUTOEXEC.BAT

    set blaster=A220 D1 I5 T3
    c:\spectrum\mscdex.exe /d:mvcd001 /m:10 /v /e

All three of the device drivers can be loaded into upper memory if there
is sufficient space.
