OS/2 INSTALLATION INSTRUCTIONS on FastCache III

1. Installing OS/2 from CD-ROM

   -  To install OS/2 to a supported boot drive via CD-ROM attached
      to the FastCache III, first use diskcopy A: A: to make a backup 
      copy of the OS/2 CD-ROM "Install Disk 1" and the OS/2 "Diskette
      for CD-ROM".
   -  Next, using the copy command, copy the file "CSCFC3.ADD" from
      the FC3 Diskette to the backup install disk.  Edit the 
      "CONFIG.SYS" file on this disk, and add the following line to
      the end of the CONFIG.SYS:
      BASEDEV=CSCFC3.ADD
   
   -  Reboot the system with the OS/2 CD-ROM "Install Disk 1" in 
      your boot drive.  When OS/2 asks for "Diskette for CD-ROM"
      insert your new disk. The installation process will be 
      completed automatically.

2. Installing OS/2 FROM FLOPPIES

   -  Proceed with normal OS/2 installation from floppies as
      described in the IBM manuals.  This procedure will complete
      using the built-in OS/2 "Int-13" driver.
   -  When the installation screen "Advanced Options" appears, 
      select the check box for prompt for "Install device support diskette".
      insert the FC3 Diskette and select OK.  This will automatically
      update the OS/2 installation to load the CSCFC3 device driver.

3.  Installing the device driver to an existing OS/2 system

    -  Select the Device Driver Install Icon in the System Setup Folder.  
       The OS/2 device driver installation program will load.  Place 
       the FC3 Diskette in the floppy drive. Select the Install button 
       to update the existing system.

DEVICE DRIVER OPTIONS

The CSCFC3.ADD driver supports all standard OS/2 ADD SCSI
command line parameters.  A description of these 
parameters is listed below.  You may view the OS/2
help file for SCSI command line parameters by clicking on the
information Icon, and selecting the command reference.  Open the
topic "OS/2 commands by name", and look up the BASEDEV command.
select Adapter Device Driver parameters for more information on how
to use these parameters as specified for CSCFC3.ADD. 
The following BASEDEV parameters are supported, with
defaults shown in parentheses:
Verbose Mode:           (/V)    /!V 
Debug Mode:             /DEBUG /DEBUG:nnnn 
Adapter No:             /A:n 
Host ID:                /ID:nn    (7)
Port No:                /PORT:nnnn (auto)
IRQ No:                 /IRQ:nn   (auto)
Ignore Adapter:         /IGNORE
Target No:              /T:n 
Disconnect Mode:        /D /D:n (/!D) /!D:n 
Synchronous Mode:       /SN /SN:n (/!SN) /!SN:n 
SCSI-2 Mode:            (/SCSI2) /SCSI2:n /!SCSI2 /!SCSI2:n 
DASD Manager:           (/DM) /DM:n /!DM /!DM:n
SCSI Manager:           (/SM) /SM:n /!SM /!SM:n
SCSI Parity:            /PARITY /!PARITY (auto detect)

The following options can be specified globally prior to an /A: option:

	/D /!D /SN /!SN /DM /!DM /SM /!SM /SCSI2 /!SCSI2 /PARITY /!PARITY


ABSTRACT

FUNCTIONAL DESCRIPTION
**********************
Release 1.x of the OS/2 2.x device driver for the CSC FastCache III 
Vesa VL-Bus SCSI-II/III controller is a fast, multi 
threaded, interrupt driven driver.  This driver supports
CD-ROM, tape, and hard disk drives.   Other devices 
supported under OS/2 and under DOS windows in OS/2 through
VASPI may be used with this driver.  The driver is most
easily loaded during a CD-ROM installation, but may also be
loaded from floppy disk as described below.  This driver
provides about a 200% speed increase over the Int-13
device driver in most applications.

RESTRICTIONS
************
The command line switch /D (for disconnect mode) will not
operate with all SCSI devices.  This option should normally
be left disabled unless several devices are connected to
the SCSI bus and all connected devices fully support 
SCSI-II disconnect features.

Due to the speed of the Fastcache III, enabling Synchronous transfer (/SN) 
doesnt improve performance that much, as the controller 
transfers data as fast as the disk driver provides it.
