________________________________________________________________
Upgrading the POST/BIOS to Bios level >= 3.
OS2 Version 2.0+
________________________________________________________________
Before upgrading the POST/Bios the new IBM2SCSI.ADD must be
copied from the POST/BIOS flash diskette to the OS2 subdirectory.
This may be done by using DDINSTAL from the OS2 command prompt
and installing this diskette when prompted, or by manually
copying the file. A trap error will occur if the post/bios is at
bios revision level >= 3 and a downlevel IBM2SCSI.ADD is installed
on the system. DELIVERY.SYS may also be added to the Config.sys
file for improved performance.
The OS2 installation diskette 1 should also be updated with the
latest IBM2SCSI.ADD at this time so that OS2 may be reinstalled
at a later time. Copy the file to a copy of installation
diskette 1.

IBM PS/2 SCSI-2 Fast/Wide Support
This README file contains instructions for installing the IBM
PS/2 SCSI-2 device drivers for OS/2 2.0 or later. It is
recommended that you print this README file prior to installing
the files.
______________________________________________________
Installing SCSI-2 Device Drivers for OS/2 2.0 or Later
------------------------------------------------------
Use the instructions in this section if you have OS/2 2.0 or
later installed.
Turn on the display and server.
Put the support diskette in drive A.
From any OS/2 full-screen session, type:
DDINSTAL
and press Enter.
Select "IBM PS/2 SCSI-2 Fast/Wide Adapter Support Installation"
from the menu and press Enter. This copies the SCSI-2 device
drivers to your hard disk and adds these BASEDEV statements to
your CONFIG.SYS file if the following statements are not there:
BASEDEV=IBM2SCSI.ADD /LED
BASEDEV=DELIVERY.SYS
If your server had IBM SCSI-2 device drivers previously
installed, and you added extra parameters to the above statement,
you need to check your CONFIG.SYS file and ensure that it has
only one BASEDEV statement for the IBM2SCSI.ADD. If you find two
similar statements, you need to delete the extraneous statement
from the CONFIG.SYS file, as follows:
REM BASEDEV=IBM2SCSI.ADD /LED
In addition, you should check for the presence of a BASEDEV
statement for the IBM2M57.ADD device driver in the
CONFIG.SYS file. If this statement is present, it should
also be deleted or removed as follows:
REM BASEDEV=IBM2M57.ADD
________________________________________________________________
Adding SCSI-2 Device Driver to the installation diskettes
________________________________________________________________
Make a copy of OS2 Diskette 1.
Copy the new IBM2SCSI.ADD from the POST/BIOS Flash Diskette to
the backup copy of OS2 Diskette 1.
Edit the CONFIG.SYS file on the backup copy of OS/2 Diskette
1 and check for the presence of a BASEDEV statement for the
IBM2M57.ADD device driver in the CONFIG.SYS file. If this
statement is present, it should also be deleted or removed
as follows:
REM BASEDEV=IBM2M57.ADD
OS2 will boot and install normally.
After installation, use DDINSTAL to install the DELIVERY.SYS
BASEDEV, or manually update the Config.sys file.
________________________________________________________________
SCSI-2 Device Drivers during CD ROM installation
________________________________________________________________
Make a copy of the OS2 Diskette 1.
Copy the new IBM2SCSI.ADD from Flash Diskette to the backup copy
of OS2 Diskette 1.
Edit the CONFIG.SYS file on the backup copy of OS/2 Diskette
1 and check for the presence of a BASEDEV statement for the
IBM2M57.ADD device driver in the CONFIG.SYS file. If this
statement is present, it should also be deleted or removed
as follows:
REM BASEDEV=IBM2M57.ADD
Install OS2 from the CD ROM. When prompted to reboot the system,
reboot the system with the OS2 install disk inserted. Insert the
backup copy of Diskette 1 when prompted.
When the Welcome to OS/2 screen appears press escape to exit to a
command prompt.
Copy IBM2SCSI.ADD from the OS2 diskette 1 or from the flash
diskette to the OS2 directory on the hard file. Copy
DELIVERY.SYS to the directory also.
Remove the diskette and reboot the system. The OS2 installation
will continue.
Add the DELIVERY.SYS line to the Config.sys file after
installation is complete.

FRU replacement of a downlevel processor
________________________________________________________________
Requires that the 3 diskettes of the Reference Diskette package
be available for all type 4 processors, as the existing processor
and the system partition may be downlevel from that of the FRU.
________________________________________________________________
OS2 2.0+ information for FRU replacement.
________________________________________________________________
The new IBMSCSI.ADD may be manually copied to the OS2
subdirectory. The following procedure will update the OS2
install diskettes and offers a method to boot to a HPFS formatted
drive.
Make a copy of the OS2 disk 1.
Copy the new IBM2SCSI.ADD from the POST/BIOS flash diskette to
disk 1.
Edit the CONFIG.SYS file on the backup copy of OS/2 Diskette
1 and check for the presence of a BASEDEV statement for the
IBM2M57.ADD device driver in the CONFIG.SYS file. If this
statement is present, it should also be deleted or removed
as follows:
REM BASEDEV=IBM2M57.ADD
Boot install disk insert disk 1 with new IBM2SCSI.ADD when
prompted
Press escape at the "Welcome to OS2" information screen to exit.
If the boot partition is FAT, skip to the next step. If the boot
partition is HPFS, insert disk 2 and type "CHKDSK", which will
load HPFS device drivers. If the Installation media was CD ROM,
the system will prompt for the CDROM and load the drivers
automatically.
Copy the new IBMSCSI.ADD to the OS2 directory. Copy DELIVERY.SYS
to the OS2 directory.
Verify the Config.sys file contains the two BASEDEV lines for
IBM2SCSI.ADD and DELIVERY.SYS.
