IBM OS/2
NOTE: To install the 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
NOTE: If you are installing the Ultra2SCSI host adapter, delete the aic7870.add driver as well.
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
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
3.Copy the driver from the Adaptec 7800 Family Manager Set diskette for IBM OS/2 onto the IBM OS/2 installation diskette #1.
a)For Ultra2SCSI host adapters, the driver (AIC78U2.ADD) will be located in \OS2\AIC787U2 directory.
b)For UltraSCSI or earlier host adapters, the driver (AIC7870.ADD) will be located in \OS2\AIC7870 directoy
