First-Time Installation of IBM OS/2 2.1X From CD-ROM
Only the AIC7870.ADD driver is supported under IBM OS/2 2.1X. The Ultra2SCSI
AIC78U2.ADD driver is not supported under IBM OS/2 2.1X.
NOTE: To install the aic7870.add driver, it is necessary to copy the driver from the
Adaptec 7800 Family Manager Set v3.00 diskette for IBM OS/2 on to the IBM OS/
2 Diskette #1. However, before you can copy the driver, you must first remove
various files from the IBM OS/2 Diskette #1, as explained in step 2 below.)
1. Use diskcopy to make backup copies of all IBM IBM OS/2 and Adaptec sup-
plied diskettes. Use the backup copies as your working diskettes.
2. Delete some of the existing files on the backup copy of the IBM OS/2 diskette
#1 so that approximately 140 KB of disk space is available on the diskette. Use
the following information to help you decide which files to delete.
a) If the Adaptec 7800 Family host adapter is the only Adaptec host adapter
installed in your system, delete all other Adaptec drivers (aha152x.add,
aha154x.add, aha164x.add, aha174x.add, aic7770.add and fd16-700.add).
b) 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.
c) If you have deleted the suggested Adaptec drivers above, and if you do not
have a Microchannel architecture system, and you still do not have approxi-
mately 140 KB of disk space available on the diskette, delete these files:
ibm2flpy.add, ibm2adsk.add, and ibm2scsi.add.
NOTE: If you have a combination PCI/Microchannel architecture system, you
need to delete third-party driver files not required.
3. Copy the OS2LDR file from the Adaptec 7800 Family Manager Set v3.00 dis-
kette (i.e., \OS2\AIC7870\OS2LDR) onto the IBM OS/2 installation. diskette.
This overwrites the existing IBM OS/2 loader on the diskette.
4. Copy the IBMINT13.I13 driver from the Adaptec 7800 Family Manager Set
v3.00 diskette (i.e.,\OS2\AIC7870\IBMINT13.I13) onto the IBM OS/2 installa-
tion diskette #1. This overwrites any existing version of the driver included on
diskette #1.
5. Copy the AIC7870.ADD driver from the Adaptec 7800 Family Manager Set
v3.00 diskette (i.e., \OS2\AIC7870\AIC7870.ADD) onto the IBM OS/2 instal-
lation diskette #1. This overwrites any existing version of the driver included on
diskette #1.
