Abstract

IBM commissioned The Tolly Group, as part of its broader “Network Interface Cards – Beyond Performance” research program, to evaluate the IBM PCMCIA adapter for Ethernet with the main focus on documenting how the card compared with industry norms in practical mobile-computing deployment areas beyond raw price and throughput. The report examines four factors that affect real-world ownership and usability for notebook users: compatibility with existing hardware and software, ease of installation and configuration, technical support, and network management features.  

The December 1994 Technology Spotlight identifies the IBM PCMCIA adapter for Ethernet as a 10Mbit/s Ethernet adapter using the PCMCIA bus. Tolly notes that this profile is an addendum to a larger six-month NIC research and testing effort that covered more than 20 adapters across Ethernet, Token Ring, and FDDI topologies and across ISA, EISA, MCA, and PCMCIA form factors. In that broader study, the adapters were evaluated not only for connectivity, but also for operational characteristics that influence deployment efficiency and long-term support costs.  

In the compatibility matrix on pages 2 and 3, the IBM PCMCIA Ethernet adapter shows broad support for common enterprise environments. The card supported NDIS 2 for OS/2 and DOS, NetWare 4.01 client support for both OS/2 and DOS, and NetWare 3.11 client support for both OS/2 and DOS. The profile indicates that IBM provided product-announcement documentation listing supported software products, operating systems, and tested PC systems. Tolly also notes that IBM did not provide server drivers for NetWare 4.01 or 3.11, which it considered reasonable because end users were unlikely to require a PCMCIA-based server configuration.  

Ease-of-use and support results were generally strong. The adapter supported automatic driver installation from a utility and included a diagnostic utility, though it did not provide an LED status indicator or upgradeable ROM. Technical support was a relative strength, with toll-free support, weekday phone support, no-charge basic support, weekend and 24-hour support, on-site service, extended support, and worldwide technical support. Online resources included BBS phone information, current driver versions, update tracking, supplementary documentation and patches, modem support at 14Kbit/s or higher, and CompuServe forum access, though not a World Wide Web server. For management, the adapter supported IBM LAN Network Manager, but not SNMP, DMTF, or proprietary management. Overall, the report presents the IBM PCMCIA adapter for Ethernet as a well-supported mobile Ethernet NIC with strong client compatibility and solid installation and support resources for notebook users.
