DOCUMENT ID:        TID300042
DOCUMENT REVISION:  B
DATE:               25JAN95
ALERT STATUS:       Yellow
INFORMATION TYPE:   Symptom Solution
README FOR:         PTF615

PRODUCT and VERSION:
UnixWare 1.1

ABSTRACT:

The ptf615 file contains PTF615 - "IDE Disk Driver Update". This PTF 
also requires a replacement boot floppy #1 diskette available 
separately in the file boot1.tar. 

SYMPTOM

Cannot install UnixWare v1.1 on machines with IDE drives. A symptom of 
the original problem was a warning from the disk driver that a disk 
driver request had timed out.  This was most common with IBM controllers.

SOLUTION

Download the ptf615.dd.Z, ptf615.txt and the boot1.tar file to the
/tmp directory on your machine.  Create a replacement IHV HBA diskette
using the ptf615.dd.Z files.  Install your system using the 
replacement for boot floppy #1 (boot1.tar), the orginial #2 and #3
diskettes from the red box.  When prompted for the IHV HBA diskette
use the replacement created from the ptf61d.dd.Z image files.

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 )

     # uncompress the image using:

          uncompress ptf615.dd.Z

Now dd the image onto the disk using:

        # dd if=/tmp/ptf615.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.

These release notes acquaint you with the information for UnixWare 
PTF615 - "IDE Disk Driver Update".  This update requires a replacement 
for the original boot floppy number one for your product (available 
separately as boot1.tar) and an HBA boot image floppy created from 
this PTF.  After booting the system using the 3 UnixWare boot floppies, 
including boot floppy #1 (replace the boot floppy #1 from the original 
product with the replacement created from the image in boot1.tar), 
the system will prompt you for the HBA floppy, use the one created 
from the disk image provided in this PTF.

The 3 boot images and the additional HBA boot floppy provide a new 
disk driver for booting and installing a UnixWare system from an IDE 
hard disk drive.  The booting problem persists when using an 
IBM WDA-L42 IDE hard disk drive.

New Features

PTF615 a new HBA boot floppy containing an updated driver for IDE hard drive.

Software Notes and Recommendations.

PTF615 updates a system file to support IDE hard drives.  The only file that
gets updated is /etc/conf/pack.d/athd/disk.cfg.

This update is for UnixWare version 1.1.

Hardware Notes and Recommendations.

The PTF is targeted for the i386 and i486 CPU's.

Installation Instructions.

The PTF consists of two 3.5 boot floppies. The first one contains the 
UnixWare boot floppy #1.  It replaces one of the original boot floppies 
(the one labeled "1 of 3"). The second floppy is an HBA boot floppy.  
To install PTF615, place boot floppy #1 (the one which was created 
using the boot1.tar file, replacing the original one) into the boot 
floppy drive (drive 0, or drive "A") and reboot the machine.  You may 
now follow the installation instructions stated by UnixWare as the 
process continues, using the original boot floppies #2 and #3.  
After processing boot floppy #1, UnixWare will prompt you to insert 
the HBA floppy into the floppy drive.  UnixWare will then continue to 
prompt you for boot floppies 2 and 3.

After processing the 3rd floppy, UnixWare will prompt you for the media 
with which you want to install the various system packages, such as the 
base package and the graphics package.  After the installation of these 
packages (usually from cartridge tape or CD-ROM) is complete, UnixWare 
will again prompt you for the same HBA floppy which you used after 
floppy #1.

Troubleshooting.

PTF615 is successful if you succeed in installing Unixware onto your IDE hard
drive, and booting from the drive.
