Solution Specifics

These release notes acquaint you with the contents of UnixWare 
PTF170 - SONY CDU HBA Driver Package

1. General Description

This PTF is a re-release of the SONY CDU HBA Driver Package. Because 
it is necessary to completely replace the original package, this 
package will be installed as the "sony" package (instead of "ptf170").  
Additionally (and also as a result of this being a package re-release), 
backup/restore processing as normally done by PTFs is not performed.

The Sony Host Bus Adapter (HBA) driver (sony) supports the Sony 
proprietary Host Bus Adapters used with the Sony CD-ROM drives CDU31A, 
CDU33A and CDU535. This driver supersedes the "cd31a" and "cd535" 
drivers originally included on the UnixWare 1.1 IHV/HBA diskette.

The following problems have been corrected in this updated package:

- Unable to successfully complete installation using the CDU535 drive.

- Excessive errors encountered on the CDU31A and CDU33A drives. Symptoms 
of this problem included mount failures and extremely long delays in 
reading even small files.

2. New Features

None

3. Software Notes and Recommendations

This PTF can be installed on any UnixWare 1.1, 1.1.1 or 1.1.2 system 
which is or will be configured with the supported CD-ROM drives.


4. Hardware Notes and Recommendations

If the driver is to be used for UnixWare installation, the controller 
must be configured to use interrupt 5 and I/O address 320H.

For the CDU31A and CDU33A drives, the HBA card must not have DMA 
enabled (do not install any jumpers on the DMA Select jumper block).

5. Installation Instructions

If UnixWare is to be installed from CD-ROM media using the Sony HBA, 
when the system prompts you to insert the "Host Bus Adapter Drivers" 
diskette, this diskette should be inserted before the UnixWare 1.1 
IHV/HBA diskette.  

If this package is being added after installation of the UnixWare 
(because the Sony CD-ROM drive is being added subsequent to UnixWare 
installation), it may be installed either via the Application Setup 
window or, from the console or an Xterm window, with the following 
command (as root):

     # pkgadd -d diskette1

After installing this package, a system reboot will be needed to 
rebuild the kernel and incorporate the driver.

Because this is a re-release, backup/restore is not performed. To 
remove this version of the package and install the previous version, 
you must first pkgrm this version, followed by pkgadd of the 
previous version.
