This is the release notice for SCO OpenServer MDI Driver Release 4.02.

The release 4.02 for Openserver 5.0.4 and 5.0.5 has the following features.

1. Driver works with shared IRQs.
2. Driver works on multi-processor systems.
3. Modified the pnt-pci file to have more options for the pci ID.

For single processor systems:
-----------------------------

To install the driver copy pnt.tar on to the floppy.
Follow steps below.

1. Ensure that the pnt driver can be installed from the CDROM using "netconfig".
2. Remove it, relink kernel and reboot.
3. Go to the directory /opt/K/SCO/pnt/5.0.4d/ID/pnt, remove and save the contents.
4. Run the following steps.
	ndinstall -d pnt
	doscp a:pnt.tar pnt.tar
	tar xvf pnt.tar >/dev/null 2>&1
	rm pnt.tar
	ndinstall -a pnt
5. Relink and reboot.
6. Now install drivers for the AMD pcnet cards using netconfig menu options.
Note: Depending on the Openserver version, you may need
to change the '5.0.4d' directory name in the above path.


For systems with multiple processors:
--------------------------------------

Before installing the drivers, install an additional processor on the 
system (which already has SCO openserver 5.0.4d on it) by running CUSTOM 
menu options. Select SMP MultiProcessor installation and add the 
additional processor by entering the license number when prompted. 

Repeat the steps for each additional processor on the system. 
Relink kernel and reboot.
Now follow the same steps mentioned above (for single processor systems)
to install the pnt driver.


Note:
1. If there are warning messages when the driver tries to register its IRQs do 
    the following:
	a. Run netconfig and remove the driver, link and reboot.
	b. For a pci device check the func#, dev# and bus# by "/etc/hw -vr pci"
	c. Now add the driver again by running netconfig.
	d. Ensure the above parameters match.
	e. For ISA devices add the card and run the system config utility before
	   installing the driver.
