DOCUMENT ID:        TID300032
DOCUMENT REVISION:  B
DATE:               25JAN95
ALERT STATUS:       Yellow
INFORMATION TYPE:   Symptom Solution
README FOR:         PTF169

PRODUCT and VERSION:
UnixWare 1.1

ABSTRACT:

The ptf169 file contains ptf169 - Driver support for LMSI CDROM models
CM205, CM225, and CM250 models and UnixWare 1.1.  To install UnixWare 
from a CD-ROM media using the "ptf169" driver, the controller must be 
configured at interrupt 5 and I/O address 340H. Note that these 
supported LMSI controllers do not support DMA. 

SYMPTOM

Support needed for LMSI CDROM models CM205, CM225, and CM250 models with
UnixWare 1.1.  

SOLUTION

Apply the ptf169 file.



Installation Instructions:

DATATYPE: compressedtar

1.  Download the ptf169.tar.Z and ptf169.txt files to the /tmp      
    directory on your machine.

2.  Read the release notes contained in this file.              

3.  Now become root, and add the package to your system using the following
    commands: (This assumes that ptf169.tar.Z is in the /tmp directory, 
    and that /tmp is the working directory.)

     $su
          (become the super user)
     #mkdir ihv
          (make a directory to hold the files)
     #cp ptf169.tar.Z ihv
          (copy file into ihv directory)
     #cd ihv
          (make ihv the working directory)
     #uncompress ptf169.tar.Z
          (uncompress the file)
     #tar xvf ptf169.tar
          (un tar the file)
     #rm ptf169.tar
          (remove the tar file)
     #/usr/sbin/format /dev/rfd0
          (format diskette1)*
     #mkfs  -F s5 /dev/dsk/f0t 2844:711 2 36
          (make file system on diskette1)*
     #mount -F s5 /dev/dsk/f03ht /mnt
          (mount diskette)*
     #find . -print | /bin/cpio -pmud /mnt
          (copy files to diskette)

Solution Specifics

These release notes acquaint you with the contents of UnixWare PTF169 -
Phillips LMSI-205 HBA Driver Package

1. General Description

This PTF is a re-release of the Phillips LMSI-205 HBA Driver Package.  
Because it is necessary to completely replace the original package, 
this package will be installed as the "lmsi" package (instead of "ptf169").  
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 LMSI Host Bus Adapter (HBA) driver (lmsi) supports the Laser 
Magnetic Storage International (LMSI) proprietary controller used 
by the LMSI CD-ROM drives CM205, CM225 and CM250.  This driver supersedes 
the "cm205" driver originally included on the UnixWare 1.1 IHV/HBA diskette.


2. New Features

With respect to the original "cm205" driver: the CM225 and CM250 drives are
now supported.

With respect to the previous release of the "lmsi" driver: there are no new
features.

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 340H.

5. Installation Instructions

If UnixWare is to be installed from CD-ROM media using the LMSI 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 LMSI 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.
