-
- RELEASE: SCO UNIX System V/386 Release 3.2 Operating System Version 4.0
-
- PROBLEM: There is a misprint in the July/August 1992 issue of SCO Magazine
- regarding how to change an Adaptec 1740 SCSI host adapter to or
- from enhanced mode. The text of the article is accurate and
- complete, but the chart on page 18 is somewhat ambiguous.
-
- SOLUTION: The chart on page 18 illustrates what mscsi looks like BEFORE
- changes are made. It reads in part as follows:
-
- Partial contents of /etc/conf/cf.d/mscsi:
-
- ha/tattach/tnumber/tID/tlun
- ad Sdsk 0 0 0 #HARD DRIVE AT ID=0
- ad/tStp/t0/t2/to/t #TAPE AT ID=2
-
-
- The chart on page 18 should read in part as follows:
-
- Partial contents of /etc/conf/cf.d/mscsi:
-
- *ha attach number ID lun
- *
- ad Sdsk 0 0 0 #HARD DRIVE AT ID=0
- ad Stp 0 2 0 #TAPE AT ID=2
-
- SEE ALSO: Another article in this database entitled "How to switch Adaptec
- 1740 SCSI host adapter to or from enhanced mode."
-
- ------------------------------------------------------------------------
-
- What is interesting is that it's still wrong. This is the text
- of item #2 which is correct (IMHO) and was probably the original
- source of the article.

- How to switch Adaptec 1740 SCSI host adapter to or from enhanced mode
-
- KEYWORDS: v4 unix scsi host switch adaptec adapter change driver link kit 1740 enhanced mode 1540 1542 standard eisa ad eiad
-
- RELEASE: SCO UNIX System V/386 Release 3.2 Operating System Version 4.0
- SCO Open Desktop 2.0
-
- PROBLEM: I have installed Version 4.0 of SCO UNIX System with an Adaptec
- 1740 SCSI host adapter in standard mode. Now I want to switch
- the Adaptec 1740 SCSI host adapter to enhanced mode.
-
- NOTE: This is not instruction on adding a host adapter to the system,
- it is simply instruction on changing an existing host adapter.
-
- SOLUTION: First, some files need to be edited and the kernel will need to be
- relinked. Then your machine will need to be rebooted in order for
- the changes to take effect. If you installed SCO UNIX System V
- Operating System with an Adaptec 1740 SCSI host adapter in standard
- mode, the operating system is using the 'ad' driver. In order to
- utilize the full functionality of the Adaptec 1740 SCSI host adapter
- in enhanced mode, the 'eiad' driver must be used.
-
- To implement this change, while logged into the system as root,
- do the following:
-
- 1. Change directories to /etc/conf/cf.d
-
- 2. Use the text editor of your choice to manually edit
- the mscsi file. You should see something similar to
- the following:
-
- *
- * [text about this file commented out]
- *
- *ha attach number ID lun
- *
- ad Sdsk 0 0 0 <--SCSI hard drive at ID=0
- ad Stp 0 2 0 <--SCSI tape at ID=2
-
- You may or may not have entries for SCSI peripherals
- other than a SCSI hard drive at ID=0.
-
- Change all occurrences of the string 'ad' in the left
- column (shown above) of the mscsi file to read 'eiad'.
-
- 3. Save the changes you have made to the mscsi file and
- quit out of the editor.
-
- 4. Change directories to /etc/conf/sdevice.d
-
- 5. Use the text editor of your choice to manually edit
- the ad file. You should see something similar to
- the following:
-
- ad Y 1 5 0 0 330 332 0 0
-
- Change the Y in the second field to an N.
- Save the change you made to the ad file and quit
- out of the editor.
-
- 6. Use the text editor of your choice to manually edit
- the eiad file. You should see something similar to
- following:
-
- eiad N 1 5 0 0 0 0 0 0
-
- Change the N to a Y in the second field. Do not
- make any other changes to this file. The zeros (0's)
- imply auto-configuration of the appropriate values.
- Save the change you made to the eiad file and quit
- out of the editor.
-
- 7. Change directories to /etc/conf/cf.d
-
- 8. Relink your kernel by typing: ./link_unix
- and press <Return>.
-
- 9. Shutdown the system.
-
- 10. Run the eisa configuration utility to change
- the mode of the Adaptec 1740 SCSI host adapter.
-
- 11. Boot your system.
-
- Your system should now be running with the Adaptec 1740 host adapter
- in enhanced mode.
-
- If you wish to change the mode of the Adaptec 1740 host adapter to
- standard mode from enhanced mode, simply follow the instructions
- above, but replace every occurrence of eiad with ad and every
- occurrence of ad with eiad.
