ELS IRQ-3 disable correction

It has been discovered that when NetWare ELS-1 is used with either the
Novell NE-1000 or the 3Com 3C501 in the file server, IRQ-3 may in a
particular instance, be taken from the network card causing the workstations
to loose their connection with the file server. This occurs ONLY when a
program written in interpretive BASIC or IBM or Microsoft Compiled version
1.0 is run on the file server/workstation.

Interrupt 3 will be taken from the lan card when the application terminates.
The only solution that is currently available is to re-configure the
operating system to use either interrupt 2,5 or 7, whichever is available.
The available options for 3C501 support are:

Configuration of LAN A Interface:
    Network address [00000001]   Node address is
determined automatically.
    Hardware Option: 3Com EtherLink
  * 0: IRQ = 3, IO Address = 300h, No DMA, No
ROM used (check decode)
    1: IRQ = 5, IO Address = 300h, No DMA, No
ROM used (check decode)
    2: IRQ = 3, IO Address = 310h, No DMA, No
ROM used (check decode)
    3: IRQ = 5, IO Address = 310h, No DMA, No
ROM used (check decode)
    4: IRQ = 2, IO Address = 300h, Not for assy
345 (check decode)
    5: IRQ = 2, IO Address = 310h, Not for assy
345 (check decode)
    6: IRQ = 4, IO Address = 300h, Not for assy
345 (check decode)
    7: IRQ = 4, IO Address = 310h, Not for assy
345 (check decode)
    8: IRQ = 6, IO Address = 300h, Not for assy
345 (check decode)
    9: IRQ = 6, IO Address = 310h, Not for assy
345 (check decode)
   10: IRQ = 7, IO Address = 300h, Not for assy
345 (check decode)
   11: IRQ = 7, IO Address = 310h, Not for assy
345 (check decode)

The NE-1000 options are:

Configuration of LAN A Interface:
    Network address [00000001]   Node address is
determined automatically.
    Hardware Option: NetWare Ethernet NE-1000
  * 0: IRQ = 3, I/O Base = 300h, no DMA or ROM
    1: IRQ = 2, I/O Base = 320h, no DMA or ROM
    2: IRQ = 4, I/O Base = 340h, no DMA or ROM
    3: IRQ = 5, I/O Base = 360h, no DMA or ROM
    4: IRQ = 2, I/O Base = 300h, no DMA or ROM
    5: IRQ = 3, I/O Base = 320h, no DMA or ROM
    6: IRQ = 5, I/O Base = 340h, no DMA or ROM
    7: IRQ = 4, I/O Base = 360h, no DMA or ROM
    8: IRQ = 4, I/O Base = 300h, no DMA or ROM
    9: IRQ = 5, I/O Base = 320h, no DMA or ROM
   10: IRQ = 2, I/O Base = 340h, no DMA or ROM
   11: IRQ = 3, I/O Base = 360h, no DMA or ROM

* is the current configuration option number

The utility "SCONFIG.EXE" will be needed to change the option. It is found
on "GENOS-3" of all 2.0a NetWare systems or can be download from NetWire
with this bulletin as "ELS-FIX.ARC." It will be necessary that a copy of
"NET$OS.EXE" resides on the same diskette as "SCONFIG.EXE." Change the
configuration option number to the one desired by typing "SCONFIG NET$OS.EXE
A:,,?" where "?" corresponds to the desired option number. The table from
the first page will be displayed with a "*" being display next to the option
number selected. Use the re-configured operating system to boot your ELS-I
file server. Before doing so, it will necessary to change the settings on
the board to match the software settings. Contact your dealer for
instructions on how to change to settings. The ELS supplied documentation
only shows how to set up the default settings.
