Adaptec 7800 Family Manager
Installing OS/2 v2.1x (Ultra SCSI Driver Only)
Follow these instructions only if you are installing OS/2 v2.1x for the
first time. We assume here that OS/2 is not already installed on the
system. You will need to have access to a computer where you can
copy DOS files from one diskette to another.
Note:
To install the aic7870.add driver, it is necessary to
copy the driver from the 7800 Family Manager Set diskette
for OS/2 on to the OS/2 installation diskette #1. However,
before you can copy the driver, you must first remove
various files from the OS/2 installation diskette #1, as
explained in step 2 below.
1
Go to a computer on which DOS, Windows
®
, or OS/2 is
already installed. Use diskcopy to make backup copies of all
IBM OS/2 and Adaptec-supplied diskettes. Use the backup
copies as your working diskettes.
2
Delete some of the existing files on the backup copy of the
OS/2 diskette #1 so that approximately 120 KBytes of disk
space is available on the diskette. Use the following
information to help you decide which files to delete:
– If the Adaptec 7800 Family host adapter is the only Adaptec
host adapter installed in your system, delete all Adaptec
drivers (
aha152x.add , aha154x.add , aha164x.add ,
aha174x.add , aic7770.add , and fd16_700.add ).
– If you have an Adaptec host adapter that is not part of the
7800 Family, delete all of the Adaptec drivers not used by
that particular host adapter. For example, if you have an
Adaptec AHA-1540CP host adapter installed in your
computer, delete all Adaptec drivers except for the
aha154x.add driver.
– If you have deleted the suggested Adaptec drivers above,
and you still do not have approximately 120 KBytes of disk
space available on the diskette, delete these files:
ibm2flpy.add , ibm2adsk.add , and ibm2scsi.add .
3
Copy the os2ldr file from the 7800 Family Manager Set diskette
for OS/2 (i.e.,
\os2\aic7870\ ) onto the OS/2 installation
diskette.
