DOCUMENT ID:        TID021516
DOCUMENT REVISION:  C
DATE:               25JAN95
ALERT STATUS:       Yellow
INFORMATION TYPE:   Symptom Solution
README FOR:         PTF606

PRODUCT and VERSION:
UnixWare 1.1

ABSTRACT:

The ptf606 file contains PTF606 -"Boot Update for IBM Thinkpad" 
a replacement IHV HBA diskette image with updated drivers to allow 
installation on an IBM Thinkpad portable computer. This PTF also 
requires a replacement boot floppy #1 diskette available separately 
in the file boot1.tar. To use this patch, you must have a working 
UNIX machine. 

SYMPTOM

Cannot install UnixWare v1.1 on IBM ThinkPad machine

SOLUTION

Download the ptf606.dd.Z, ptf606.txt and the boot1.tar file to the /tmp 
directory on your machine. Create a replacement IHV HBA diskette using 
the ptf606.dd.Z file.  Install your system using the replacement for 
boot floppy #1 (boot1.tar), the original #2 and #3 diskettes from the 
red box.  When prompted for the IHV HBA diskette use the replacement 
created from the ptf606.dd.Z image.

Installation Instructions:

DATATYPE: compressedimage

To create a diskette from an IHV HBA disk image file included in this PTF,
become superuser and format a 3.5 inch 1.44MB diskette using:

        $ su
                provide root password at Password: prompt
                place a 3.5 inch high density disk in the floppy drive

        # format -v /dev/rdsk/f03ht  ( f13ht if it's the b: drive )

Now uncompress the file using:

        # uncompress ptf606.dd.Z

Now dd the image onto the disk using:

        # dd if=/tmp/ptf606.dd of=/dev/dsk/f03ht bs=1024k

                note path to dd image may be different
                use f13ht of it's the b: drive

Solution Specifics

General Description.

This update consists of two 3.5 inch boot floppies to enable loading of
Unixware 1.1 onto an IBM Thinkpad.  The two boot floppies are:

   1) The standard "Boot Floppy 1" (Boot Floppy 1 of 3 - downloaded separately
as boot1.tar )
     
   2) A new IHV/PTF606 floppy, to be loaded immediately after the first boot
floppy, and after the system has been loaded.

New Features.

PTF606 resolves a problem where Unixware 1.1 could not be loaded onto an IBM
Thinkpad 750C with a 2.88 MB floppy drive.

It also resolves various problems with other IBM ThinkPad models as well such
as the Model 300 and the Model 500.

The floppy disk software driver has been corrected to detect media in all
Thinkpad models.

This PTF contains a disk image of a new IHV HBA diskette with drivers 
modified to allow installation on a IBM ThinkPad. This file, along with 
boot1.tar ( a replacement for "Boot Floppy 1" ) enable UnixWare 1.1 to 
be installed on an IBM ThinkPad.  The IHV HBA floppy is loaded immediately 
after the Boot Floppy 1, and after the system has been loaded.

Software Notes and Recommendations.

This update is for Unixware version 1.1 and later. Note driver found in this
package is also contained in update 1.1.2

Hardware Notes and Recommendations.

The PTF is targeted specifically for the IBM Thinkpad 750C, containing a 2.88
MB floppy and for IBM ThinkPad Models that exhibit read errors when trying to
install UnixWare 1.1 from the supplied boot floppies.


Installation Instructions.

Create two diskettes from disk images ( the first boot floppy #1 from
boot1.tar, and the IHV HBA diskette created from the disk image in this file,
ptf606.dd.Z )

The PTF consists of two 3.5 inch boot floppies.  One of the floppies is
labeled "Boot Floppy 1" (1 of 3).  Substitute this boot floppy for the
original "Boot floppy 1" in Unixware version 1.1.  Place this first boot
floppy into the floppy drive, boot the system, and follow instructions. When
processing of the first boot floppy is complete, you will be prompted to load
either the next boot floppy (Boot Floppy 2), or an IHV floppy.  At this point,
place the new IHV/PTF606 floppy into the floppy drive and press "Return", 
and continue to follow instructions.  You may also have a need to load 
other IHV boot floppies as well.

For example, if you have an Adaptec 1740 HBA configured in enhanced mode, you
must install the IHV/HBA boot floppy.

After the system is loaded, you will once again be prompted for all IHV
floppies that were installed after Boot Floppy 1.  Insert the IHV/PTF606
floppy into the floppy drive and press Return.

Caveat.

If you are installing UnixWare 1.1 on an IBM ThinkPad Model 300/500 it is
required that you DISABLE the following items in the POWER SAVING MODES:

        Power Management
        Doze Mode
        Auto Hibernate

These can be ENABLED again once you have successfully loaded UnixWare 1.1.

In addition, you must perform the following commands (as "root") on an IBM
ThinkPad 750C with the 2.88 MB floppy driver AFTER the system is installed:

        modadmin -U fd
        /etc/conf/bin/idtune FD_DOOR_SENSE 0

          (this will prompt for a "yes/no" answer for verification).

        modadmin -l fd

These steps may also be required for other ThinkPad models.  They can be
executed if a command fails to access the floppy drive in a normal fashion to
determine if that is the cause of the problem.

Troubleshooting.

PTF606 is successful if you succeed in loading and processing all boot
floppies.
