Sony CDU-31A device driver for the Windows NT(tm) operating system
Beta Release 06/01/93
------------------------------------------------------------------------

These files comprise a Beta version of a device driver supporting the
Sony CDU-31A CD-ROM drive under the Microsoft Windows NT operating
system. These drivers require a March 1993 or newer version of the
operating system.

THIS IS A BETA TEST RELEASE ONLY

The purpose of this release is to test the device driver under a variety
of system configurations. If you experience any problems, send a
detailed report to the CompuServe ID listed at the end of this document.

The device drivers and this file are owned by Sony and protected by
United States copyright laws, international treaty provisions, and all
other applicable national laws. You may not reverse engineer, decompile,
or disassemble the device drivers.

Files enclosed:
OEMSETUP.INF - required for maintenance mode driver setup
READ.ME - this file
SLCD32.SYS - device driver for Windows NT - x86 processor.
SLCD32.M - device driver for Windows NT - Mips processor.
SLCD32.A - device driver for Windows NT - Alpha processor.
TXTSETUP.OEM - used during text setup, initial system install.

Copy all files to the root directory of a floppy disk and mark it
'Sony - CDU-31A setup disk. Beta Version'. If you are installing on a
Mips or Alpha based computer then copy the appropriate driver to the
file SLCD32.SYS. You must also change the last line in the file
OEMSETUP.INF. Change the value for SIZE to the new size of the file
SLCD32.SYS.

Installing from a CDU-31A - x86 processor
-----------------------------------------
To install Windows NT from a CDU-31A drive with no other supported SCSI
host adapter installed, boot the computer from the Boot floppy provided
with the operating system. After you hit ENTER to indicate 'install now'
and then choose either Express or Custom install, the installation
software searches for a supported host adapter and CD-ROM drive. It
displays 'Scanning for SCSI adapters' in the bottom of the screen. The
device drivers used during this phase of installation are expected to be
on the Windows NT CD-ROM disc, which these currently are not. When the
scan is complete, the install program asks if you want to 'Configure
Additional SCSI adapters', hit 'S' to select this. It then displays a
list of adapters with the last line highlighted reading: 'Other (Requires
disk provided by a hardware manufacturer)'. This is the setup floppy
created above. Hit Enter to select other, the program prompts to insert
the floppy, do so and hit Enter again. The install program then reads the
slcd32.sys device driver from the floppy, installs it, finds the CDU-31A
drive and uses it to install the operating system.

The install program also makes all of the necessary registry entries
automatically.

For this to work the CDU-31A host adapter MUST be set for IRQ 3. If the
host adapter jumpers are later changed the registry must be manually edited
using REGEDT32.

Adding support for CDU-31A to a pre-existing NT system
------------------------------------------------------
Within Windows NT under the window 'main', 'Windows NT Setup' select
'Options', then 'Add/Remove SCSI Adapters'. Then click on the 'Add'
button. In the window 'Select SCSI Adapter Option', scroll the 'Adapter'
selection down to 'Other (Requires a disk from a hardware manufacturer)'.
Click on this option and when prompted insert the floppy with the Sony
files. The system copies the device driver from the floppy and makes all
the necessary registry entries automatically. These entries assume an
IRQ of 3. If the host adapter jumpers are later changed or if you are
using an IRQ other than 3, the registry must be manually edited using
REGEDT32.

31A Unique registry entry data
------------------------------
In addition to the normal mini-port stuff, the registry entry allows
specifying a base port address for the host adapter and which IRQ it's
set for. If the base port address is specified, then the driver does
not do its search for a host adapter and drives.

Specifically, under the entry for Slcd32 add a key for 'Parameters', and
under this add the key 'Device0'. This is for the first host adapter.
Under this add a value named 'DriverParameter' of type REG_SZ. This is
a string where you can specify the parameters. Entries are of the
form: 'name = value' where allowable names are: 'base' and 'irq'. Upper
or lowercase is not important and all values are hex. Entries are
separated by spaces. For example to specify the defaults of the adapter
jumpers and driver use the value:
base = 340 irq = 3
The driver defaults to irq 3 and will search for a host adapter and
drives if no entry is made. The hex port addresses searched are:
340, 230, 330, 350, 360, 250, and 348

The base address and irq must match the host adapter jumper settings.
Note that the Sony host adapter model CDB-334 does NOT come shipped
with an irq selected since interrupts are not used with the DOS device
driver.

For installation, my registry entry is:

HKEY_LOCAL_MACHINE
SYSTEM
CurrentControlSet
Services
Slcd32 -> Type: REG_DWORD: 0x1
Start: REG_DWORD: 0x0
Group: REG_SZ: SCSI miniport
ErrorControl: REG_DWORD: 0x1
Tag: REG_DWORD: 0x14
Parameters
Device0 -> DriverParameter: REG_SZ: base = 340 irq = 3


CD-ROM not accessible after reboot
----------------------------------
If your CD-ROM drive is not accessible once you reboot your computer,
use REGEDT32 to edit the registry data. The installation process creates
a value named 'Security' under the entry:

HKEY_LOCAL_MACHINE
SYSTEM
CurrentControlSet
Services
Slcd32 -> Security: REG_BINARY: ...

Delete this value and restart the system.
