ISA Plug and Play Trouble-Shooting Flow Chart

Which OS is yours?

Was your NT system installed on this machine?
(the hard disk was not moved to this machine
from another machine on which the NT system
was installed)

Please reinstall the NT system on this machine to make sure
that your system can work well completely on this machine.

Did you install the basic network components after installing
the add-on Service Packs?

If it was the first time to install the basic network
components when you installed the (ISA PnP) network adapter,
the NT system also copied some source files from the
Windows NT CD-ROM, which over-wrote some new files
installed by the Service Pack. Therefore, there are some
problems hidden in the NT system.
Please reinstall the Service Pack into your NT system.

Is the Plug and Play adapters activated by the system BIOS?

Please let the system BIOS activate the Plug and Play
ISA adapters when the system boots.
For example, if your system BIOS is an AWARD BIOS,
please set the "PnP OS Installed" option or another one
with the similar wording to be "No". (If you set that
option to be "YES", the system BIOS won't activate the
Plug and Play adapters itself. The system BIOS will let
the operating system built with the PnP function to activate
the Plug and Play adapters (assign all resources (IRQ, I/O)
for the Plug and Play devices). Then the problem occurs,
because the Windows NT system doesn't support the PnP function.

Can the ISA PnP adapter get its own unique resources (IRQ number and I/O port)?

Add some available resources by removing or disabling
some other useless devices.

For example,

• Go to the BIOS SETUP program to disable the ACPI power saving
  sub-system, which usually occupies one IRQ number.



• If your display card is without the 3D co-processor,
  you can let the display card not to use any IRQ, or let
  the display card and the other device share one IRQ.
  Then one more available IRQ will be released for being
  assigned to the ISA PnP adapters.
  For example, go into the BIOS SETUP program, set the option
  named perhaps "VGA uses an IRQ" to be "Disabled" or "No".

Can the ISA PnP adapter get its own unique resources (IRQ number and I/O port)?

Using Non-PnP mode:

Boot the computer into a pure DOS system, not a DOS prompt
window in the Windows system. Run the UTIL.EXE (or EUTIL.EXE,
JUTIL.EXE). And follow the steps below to give the wireless
ISA adapter a set of fixed resources:

1. Go to the Configuration page.
2. Set it to be Non-PnP mode by unchecking the "PnP mode" option.
3. Select an IRQ which is not used by the other devices in your computer.
4. Select an I/O which is not used by the other devices in your computer.
5. Click the "OK" button or press [Alt]+[O] keys combination to save.
   this set of configuration into your wireless ISA adapter.

1. Disable the onboard Serial Port 2 in the BIOS SETUP.
2. Assign IRQ 3 to the ISA Non-PnP adapter (e.g. In the AWARD BIOS, assign
   IRQ 3 to "Legacy ISA" on the "PNP/PCI CONFIGURATION" sub-page).
3. Reset the ESCD configuration data of the PnP sub-system (e.g. In AWARD
   BIOS, set the "Reset Configuration data" option to be "Enabled" on the
   "PNP/PCI CONFIGURATION" sub-page).
4. SAVE & EXIT the BIOS SETUP program.

In the list of the Device Manager, is there the exclamation
mark on the "wireless ISA PnP adapter" device?

Remove the "wireless ISA PnP adapter" device in the Device Manager,
restart the Windows system, and reinstall the driver of the ISA PnP adapter

Can the ISA PnP adapter get its own unique resources (IRQ number and I/O port)?

  Then one more available IRQ will be released for being
  assigned to the ISA PnP adapters.


For example,


• Go into the BIOS SETUP program, set the option named
  perhaps "VGA uses an IRQ" to be "Disabled" or "No".



• In the Windows 9x system, change the IRQ, e.g. 11,
  of the sound card to that IRQ, e.g. 5, being used
  by the display card. Then the IRQ 11 becomes an
  available IRQ and the ISA PnP adapter can use it
  automatically after being applied restarting.

In the list of the Device Manager, is there the exclamation
mark on the "wireless ISA PnP adapter" device?

Remove the "wireless ISA PnP adapter" device in the Device Manager,
restart the Windows system, and reinstall the driver of the ISA PnP adapter.

Can the ISA PnP adapter get its own unique resources (IRQ number and I/O port)?

Try activating the ISA Plug and Play adapters by different systems:

Do the process as follows:

1. Remove the wireless ISA PnP adapter from the Device Manager.
2. Restart the computer and go into the BIOS SETUP program.
3. Change the system in charge of activating the ISA Plug and Play
   adapters. For example, in AWARD BIOS, change the "PnP OS Installed"
   option from "No" to "Yes", or from "Yes" to "No".
4. Reset the ESCD configuration data of the PnP sub-system (e.g. In AWARD
   BIOS, set the "Reset Configuration data" option to be "Enabled" on the
   "PNP/PCI CONFIGURATION" sub-page).
5. SAVE & EXIT the BIOS SETUP program.

1. Go into the BIOS SETUP program. Assign the IRQ, e.g. 11, of the 
   display card to the Non-PnP ISA adapter. (e.g. In the AWARD BIOS, set
   the IRQ 11 to be "Legacy ISA" on the "PNP/PCI CONFIGURATION" sub-page)
2. Reset the ESCD configuration data of the PnP sub-system (e.g. In AWARD
   BIOS, set the "Reset Configuration data" option to be "Enabled" on the
   "PNP/PCI CONFIGURATION" sub-page).
3. SAVE & EXIT the BIOS SETUP program.

Start the Windows 9x system again, install the driver for the
wireless ISA Non-PnP adapter by following the Installation
Guide of the Non-PnP mode and then follow the system's
instruction to restart your computer.
[Note]
If the Non-PnP driver has been ever installed, you don't
have to install it again, just pass over this step and
go ahead to the next step.

Can the wireless ISA Non-PnP adapter work properly now?
