12. Select Save parameters and load driver to continue.
13. Choose Exit to return to the server console prompt.
Note
If you are performing an initial installation of NetWare 5.x or 6.0 and
have more than two adapters installed, the install program allows
you to allocate the actual number of packet receive buffers needed
by the adapter. During installation, make sure the RxBuffers value is
set to 32 which is the minimum number of buffers the driver requires
for each adapter. While this setting affects adapter performance, it
allows installation of the operating system and up to eight adapters
during the initial installation. After installation is complete, increase
the number of buffers allocated to the driver as described in
“Verifying or Modifying Adapter Parameters” on page 88.
14. 5.x or 6.05.x or 6.0 NetWare 5.x or 6.0 has been successfully installed,
set the minimum packet receive buffers parameter in the startup.ncf
file to 1500 for each adapter in the system.
Set the maximum packet receive buffers to three times the minimum
packet receive buffers. Typically 4 MB of RAM is required per 1000
receive buffers. For more information, see “Verifying or Modifying
Adapter Parameters” on page 88.
15. In the autoexec.ncf file, delete the packet receive buffers parameter
(RxBuffers=32) in the load statement for this adapter. Deleting the
receive buffers phrase from the load statement resets the receive
buffers parameter to the default value of 200 for this adapter.
Note
The server needs to be restarted for the new configuration.
Example: The default maximum number of receive buffers for the system
is 500; the default minimum is 128. Edit the startup.ncf file to have the
following entries. The actual numbers will be a function of the number of
ports in the system. The following is an example for a system with 8 ports
installed:
set maximum packet receive buffers = 36000
set minimum packet receive buffers = 12000
