Server: Novell does not support ARCNET adapters at the file server as of NetWare 4.11.
Client: 16-bit ARCNET drivers are supported by NetWare 4.11's Client 32. 32-bit ARCNET drivers are not supported.
In order to get ARCNET clients under Novell connected to a NetWare 4.11 file server, you need to have an IPX protocol router between the clients that use ARCNET and the Ethernet file server.
The PCI20 will work as a client, but not as a host at the file server. CCSI does not have a specific ODI driver for the PCI20. You can, however, use the PCX20 ODI driver with the PCI20 card. In order to install the PCX20 ODI driver you must perform the following steps.
