the resources assigned by the LAN1xxxxxx keywords in the CARDID.INI file. The LAN1MEMORYBASE2 entry can be ignored.

A driver failed to load, and I’m NOT using Card and Socket Services

A. Verify that a block of memory for use by the PRO/100 PC Card has been excluded from any memory manager being loaded. Memory manag- ers are generally loaded in the CONFIG.SYS. The following example is given for EMM386.EXE and a PRO/100 PC Card loading at its default memory address of D2000:

DEVICE=C:\PATH\EMM386.EXE NOEMS X=D200-D3FF

B. Verify that power management has been disabled and the PCMCIA socket is powered/enabled in the computer system’s CMOS setup. These settings may not be present in all machines. Consult your computer documentation for information on how to access and modify the system setup.

C. Reboot the machine by turning off the power and turning it back on again (cold boot). If the driver still fails to load, the cause is generally a resource conflict. Common causes of resource conflicts include sound systems, other PCMCIA adapters, and built in ROMs. The resources required for a PRO/100 PC Card include a memory window (MEM keyword), a LAN interrupt (INT keyword, and an I/O address (IOADDRESS keyword). The default settings are indicated below.

Review your computer documentation to determine what resources are available, or use a trial and error approach. The table below shows a suggested trial and error sequence. If you use this method, be sure to add a memory exclusion from C000-DFFF to the EMM386 line until a suitable memory location has been found. Then the memory exclusion can be reduced to an 8K window. Perform a cold boot between each trial to ensure that the PRO/100 PC Card and PC Card sockets are completely reset.

When the PRO/100 PC Card driver is loaded it either reads a configura- tion file or uses command line parameters to determine which resources it should use. The following is a list of driver types, driver file names, and the configuration method used by each:

PRO/100 specifications

The Intel PRO/100 network adapter series, introduced in the mid-1990s, revolutionized networking by providing robust performance and reliability for both desktop and server environments. These adapters were pivotal in enabling fast Ethernet connectivity, helping to establish standards that would be instrumental in the advancement of network technology.

One of the primary features of the Intel PRO/100 series is its support for 10/100 Mbps Ethernet speeds. This dual-speed capability allowed organizations to transition seamlessly from older 10 Mbps networks to faster 100 Mbps connections without the need for a complete hardware overhaul. This adaptability made the PRO/100 cards a flexible choice for various network architectures.

Another significant characteristic of the Intel PRO/100 is its use of advanced bus mastering technology. This feature enhances data throughput by allowing the network adapter to take control of the system's bus when transmitting data. By doing so, it minimizes CPU overhead, which results in better overall system performance and efficient network communication. This was particularly beneficial in environments where network traffic was heavy, allowing the processors to handle other tasks without being bogged down.

The Intel PRO/100 series was also incorporated with Intel’s Plug and Play technology. This innovation simplified the installation process, automatically detecting the hardware and configuring it to work with existing system resources. As a result, system administrators could save time and reduce errors during setup, making it an attractive option for businesses looking to streamline their IT operations.

In terms of compatibility, the PRO/100 adapters supported a variety of network operating systems, including Windows NT, Linux, and Novell NetWare, providing users with a versatile solution for integrating into existing infrastructures. Furthermore, the cards were designed with high-quality, durable components to ensure longevity and reliability even in demanding environments.

Intel also emphasized the importance of network security and management with these adapters. The PRO/100 series featured capabilities for diagnostics and performance monitoring, allowing administrators to quickly identify and resolve network issues. Advanced features like Wake-on-LAN (WoL) provided additional functionality, enabling remote management and maintenance.

In conclusion, the Intel PRO/100 network adapter series represented a significant leap in networking technology during its time. With features such as dual-speed functionality, bus mastering, Plug and Play installation, and extensive compatibility, it laid the foundation for future innovations in network communication, solidifying Intel's reputation as a leader in networking solutions. Whether for small businesses or large enterprises, the PRO/100 series offered the reliability and performance critical to maintaining efficient and effective network operations.
