1) Copy the *.LAN files to the SYSTEM-1 diskette (or to the AUXGEN diskette if you are using 2.1x version of NETWARE).
2) Copy the *.OBJ files to the LAN_DRV_001 diskette.
3) Regen the NET$OS.EXE with these new drivers.
Please refer to the VIRTUAL DRIVER information below for information on the following drivers:
A8022 LAN 152 5-12-93 3:24p
A8022 OBJ 3,620 4-14-93 11:19a
B8022 OBJ 3,620 4-14-93 11:19a
C8022 OBJ 3,620 4-14-93 11:19a
D8022 OBJ 3,620 4-14-93 11:19a
VIRTUAL DRIVERS (ETHERNET_802.2)
The A8022 lan drivers are virtual 802.2 drivers which may be linked into 2.2 servers (requiring the regeneration of the operating system file NET$OS.EXE). These virtual drivers allow both 802.3 and 802.2 frame types to exist on a single physical LAN.
Virtual Lan Driver Restrictions:
1. The 802.2 virtual driver is only designed to work on Netware 2.2 servers.
2. Only lan drivers written that support Apple Talk phase II will function with the virtual 802.2 driver. If you attempt to use a driver that doesn't support Apple Talk phase II the symptom would be similar to the following:
FOR EXAMPLE If Nic Card were lan A and virtual driver were lan B
a. INSTALL would work and you could link and configure the NET$OS.EXE correctly.
b. When the server tries to come up, you could see something similar to garbage caracters when initializing lan B:
INITIALIZING LAN A.
INITIALIZING LAN B #**@%&$$$%@&$&#&@#&$@&@#&&@$&$(!(*
3. All Ethernet_802.2 packets on Netware 2.2 will have a max packet size of 1/2 a Kilobyte. This is due to an architectural limitation, because 802.2 has an additional 3 bytes in the header that the 802.3 packet did not.
4. 802.3 and 802.2 on the same physical LAN board represent 2 different logical LANs. There can only be a maximum of three physical ethernet LAN boards in the system if they are to both support the two frame types.
EXAMPLES: NON DEDICATED 2.2 server with 3 NIC cards would be configured as follows:
LAN A - NE2 NET = 1
LAN B - NE2 NET = 2
LAN C - NE2 NET = 3
LAN D - Virtual Driver. NET = 4
NON - DED NET = 5
Booting the server would show.
INITIALIZING LAN A (LAN A NET=1 ETHERNET_802.3
INITIALIZING LAN B (LAN B NET=2 ETHERNET_802.3
INITIALIZING LAN C (LAN C NET=3 ETHERNET_802.3
INITIALIZING LAN D (LAN D NET=4 ETHERNET_802.2 on LAN A
INITIALIZING LAN E (LAN E NET=5 (Non-dedicated w/s)
INITIALIZING LAN F (LAN F NET=4 ETHERNET_802.2 on LAN B
INTITALIZING LAN G (LAN G NET=4 ETHERNET_802.2 on LAN C.
NOTE: Notice that you would then have to run Dconfig on lans F and G to make the net address whatever that frame type's net address is for the given ethernet segment.
5. You must use the new DCONFIG.EXE contained in NE286.EXE to change the net addresses for FRAME ETHERNET_802.2 for LANS F and G.
NOTE: The Macintosh Apple Talk phase II VAPs for NetWare v2.15 and v2.2 products can coexist with the 802.2 virtual driver.
To implement the 8022 virtual lan drivers do the following steps:
1. Run NETGEN.EXE (2.x) or INSTALL.EXE (2.2)
2. Select the Lan driver for the Lan adapter being used (this will be assigned to LAN A).
3. Now select the Virtual 802.2 Lan driver as the second lan adapter in the system (this will assign the virtual lan driver to LAN B).
Note: If you have two cards in the server that need to support 802.2 frames select the second physical Lan adapter as the second card (assigned LAN B in the system), and then select the 8022 lan drivers as the third Lan adapter (it will be assigned LAN C and LAN F respectively).
