Diagnostics and Troubleshooting
4-5
ERT
specifies Advanced Look-ahead Pipelining threshold. Valid
settings are LOW, MEDIUM, and HIGH. Changing this value will
affect network performance, depending on the computer system.
INT, INTERRUPTNUMBER
see IRQ.
INTERRUPTSTYLE (For 32-bit NDIS3 Driver CBE.SYS only)
forces the driver to use ISA IRQ routing or PCI IRQ routing. Some
CardBus bridges have the capability of supporting both PCI and
ISA style IRQ routing. Valid parameters are AutoDetect, PCI-IRQ,
and ISA-IRQ.
IOADDRESS, IOBASEADDRESS
specifies the base I/O address of
the Xircom adapter I/O ports, in hexadecimal notation. The Xircom
CardBus adapter requires 128 contiguous I/O addresses if run in I/
O mode. If using memory-mapped I/O mode, no I/O ports are
necessary. If not used, driver will detect an I/O port automatically.
I/O PORT
see IOADDRESS
IRQ
specifies a hardware interrupt for the adapter. If PCI interrupts
are used on the CardBus bridge, this parameter is ignored (unless
the ISAIRQ keyword is used as an override). If this parameter is
not specified the driver will detect an IRQ automatically.
ISAIRQ
use this keyword to force ISA IRQ routing. Some CardBus
bridges have the capability of supporting both PCI and ISA style
IRQ routing. The driver automatically determines the best choice
for this option unless this keyword is used as an override.
LATENCY
specifies the latency timer for the CardBus bridge. This
parameter affects the bus mastering capabilities of the CardBus
adapter. Changing this parameter may affect system performance.
The range is a decimal number between 1 and 255. The latency
should be lowered if more than one peripheral device, such as a
modem, is being used. If the CardBus Ethernet 10/100+Modem 56
is the only peripheral being used, use a higher latency, such as
255.
LINEMODE
(
For 16-bit DOS Drivers)
selects either half-duplex
or full-duplex mode for the network. Valid parameters are AUTO,
HALF or FULL. Selecting full-duplex enables the RealPort CardBus
Ethernet 10/100+Modem 56 to send and receive data simulta-
neously when connected to a full-duplex hub.
