3Com 3C319 - Manual (Page 51)

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.
