3Com 3C319 manual Configuration Options

Configuration Options 5-11

IRQ Driver Type —Provides a choice of IRQ signal drivers to the ISA bus. The level-sensitive type relies on the motherboard circuitry for reliable operation and allows shared interrupts. Edge triggering is a more robust technique because it is independent of motherboard circuitry, but does not allow shared interrupts. The default is edge-triggered.

AutoSwitch —When enabled, allows installation of the 3C319 NIC in an EISA PC by the EISA configuration utility without running the 3TRDIAG program first. The default is disabled. Do not enable AutoSwitch if you installed the 3C319 NIC in an ISA PC.

Boot PROM —When enabled, allows the PC to boot from a server. The default is disabled.

Zero Wait State —When enabled, allows the PC to communicate with the 3C319 NIC 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.
