IRQ specifies a hardware interrupt for use by the
adapter. If the computer system uses PCI
interrupts 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 the driver to use 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 PRO/100 CardBus adapter.
Changing this parameter may affect system
performance. The range is a decimal number
between 1 and 255. The default is 32. The
default is 32. The latency should be lowered if
more than one peripheral device, such as a
modem, is being used. If the PRO/100 CardBus
adapter is the only peripheral being used, use a
higher latency, such as 255.
LINEMODE For 16-bit DOS Drivers: LINEMODE selects
either half-duplex or full-duplex mode for the
network. Valid parameters are AUTO, HALF or
FULL. Selecting full-duplex enables the
PRO/100 CardBus adapter to send and receive
data simultaneously when connected to a full-
duplex hub. Default is AUTO.
For 32-bit NDIS3 Driver (M32A.SYS):
LINEMODE selects either half-duplex or full-
duplex mode for the network. Valid parameters
are AutoDetect, Half Duplex, and Full-Duplex.
Selecting full-duplex enables the PRO/100
CardBus adapter to send and receive data
simultaneously when connected to a full-duplex
switch. Default is keyword is AutoDetect.
LINESPEED For 16-bit DOS Drivers: LINESPEED forces
operation to 10 or 100 Mbps. If the keyword is
not present the line speed will be automatically
detected (default).
