INSTRUCTIONS ON INSTALLING THE DSerial-500 IN WIN NT 4.0
(USE ALSO FOR SSerial-550 IN WINDOWS NT 4.0)

1) Boot into NT without the DSERIAL-550 installed in
the computer.

2) Check for available IRQs.
Go to Start|Programs|Administrative Tools|
Windows NT Diagnostics and enter the Resources Tab.
Check for a free IRQ in here. NT does not show the IRQ
for parallel ports. By default the motherboard Parallel
Port uses IRQ7,so, assume IRQ7 is not free. 
Also our card has IRQ 9 printed as IRQ 2. So if IRQ 9 is
available then set our card's jumper to IRQ2.

3) Find out which Input/Output Address the OnBoard
Serial port is using.

Go to Start|Programs|Administrative Tools|
Windows NT Diagnostics and enter the Resources Tab,
then Click the Devices button. Double-click the Serial
device. This shows your motherboard's serial port
address. Do not set our card to this address. Set our
card to the next address. For example:

  COM1 = 3f8
  COM2 = 2f8
  COM3 = 3e8
  COM4 = 2e8

Therefore, if you see 3f8 and 2f8 then set our card
to 3e8 and 2e8 (COM3 and COM4 respectively).

4) Shut down and put our card in the ISA slot.

5) Reserve the IRQ in the BIOS setup. The steps
described here apply to all Lava Cards that have IRQ
jumper settings. To correct this situation it is
necessary to make some BIOS settings changes. The
following steps apply to an Award BIOS
version 4.51 PG. Consult your motherboard manual to
find similar settings changes and how to enter
your BIOS setup. 

  Enter PNP CONFIGURATION SETUP.
  Change RESOURCES CONTROLLED BY from AUTO to MANUAL.
  Scroll down to the IRQ assigned to our card
  and change that IRQ from PCI/ISA PnP to Legacy ISA.

6) Boot back into NT and verify that our card
has installed. Go to Control Panel Ports. Ensure that
the ports that were added are set to the correct IRQ
and I/O addresses. If not then set them to the
correct settings then reboot.

Go to Start|Programs|Administrative Tools|
Windows NT Diagnostics and enter the Resources Tab,
then Click the Devices button. Double-click the
Serial device.

If you see an additional set of input output ranges
then you have successfully installed our card.
