Other Configuration Options

The TokenDisk diskette Configuration and Diagnostic Program also allows the selection of the following additional parameters:

Memory Mode – allows operation with 8-bit or 16-bit memory interfaces. The default is 16-bit, but the 8-bit option is provided for backward compatibility with older PCs.

I/O Mode – allows operation with 8-bit or 16-bit I/O interfaces. The default is 16-bit, but the 8-bit option is provided for backward compatibility with older PCs.

IRQ Driver Type – provides a choice of IRQ signal drivers to the ISA bus. Level-sensitive relies on the motherboard circuitry for reliable operation and allows shared interrupts. Edge- triggered is more robust because it is independent of the motherboard circuitry, but it does not allow shared interrupts.

AutoSwitch – when enabled, allows installation of the adapter in an EISA PC by the EISA configuration utility without having to run the 3TOKDIAG program first. The default is disabled.

Boot PROM – when enabled, allows the PC to connect to a remote network. The default is disabled.

Zero Wait State – when enabled, allows the PC to communicate with the adapter more quickly. Some PCs may not operate correctly with this option enabled. The option can be disabled to solve this problem. The default is enabled.

3Com recommends that you not change the setting of these options.
