0910 -
091001 - Follow up ref SDS 3 0000, ref SDS 2 0000.
091002 -
091003 - Have been unable to use the printer the past few weeks.  Today tried
091004 - changing the printer port assignment, but his did not solve the
091005 - problem.

091403 -
091404 - Follow up ref SDS 3 0494.
091405 -
091406 - About a month ago the boot sequence on CPU 08 began reporting conflict
091407 - with port 378.  There was a message that pressing F1 would allow boot
091408 - up to continue.  I used that for about a week or so.

091410 -    [On 980706 Brad with Mountain Computer fixed this. ref SDS 5 3510]
091411 -
091412 -    [On 990419 solved similar problem on CPU10. ref SDS 7 5510]
091413 -
091414 - I called Morris and he suggested changing the assignment of the
091415 - printer from port 0378.
091416 -
091417 - The procedure is to open the CMOS setup screen during boot up by
091418 - pressing Del key.
091419 -
091420 - In the CMOS screen select "Integrated Peripherals."
091421 -
091422 -     Near the bottom is an option for LPT.
091423 -
091424 -     Use PgUp and PgDn to scroll through choices.
091425 -
091426 - I selected the next option.  I have forgotten what it is, so today, I
091427 - checked W98...

091452 -
091453 -     ...per ref SDS 3 0494.
091454 -
091455 - So it looks like we need to change the assignments on the printer

091480 -
091481 -        ...since that is the only assignment that does not return a
091482 -        conflict during boot up and it is for LPT1.
091483 -
091484 -           I tried to print a test page and it failed.

091912 - The person who answered suggested there may be nothing wrong with the
091913 - LPT controller.  He suggested removing the W95 printer driver and
091914 - installing it again.
