Enhanced-mode adapters can be located at most addresses and can be
selected by either their UAA or ofdinal number (1=lowest UAA, 2=highest
UAA).
RECEIVEBUFFERSIZE
Default: Varies with mode.
Range: 192-2048 (Version 3.33)
Changes the adapter shallow-mode receive buffer size. Allows tuning of
receive buffers to more closely match the LAN traffic environment. This
parameter is not needed for normal operations. Value must be a multiple of
8 bytes. Smaller values increase performance and processor utilization
while larger values decrease performance and lower processor utilization.
DATARATE
Default: varies
Range: 4 or 16 (Version 3.36b and higher)
Used to set the adapter data rate for dual-speed adapters. Some
dual-speed adapters, notably MCA adapters, might not support this
keyword. If the speed selected does not match the ring speed, the open will
fail. On PCMCIA adapters, see the complementary keyword, autoringspeed.
SRAMSIZE
Default: 4
Range: 4, 8, 16, 32 or 64 (Version 4.01 and higher)
PCMCIA only in the Windows 95 environment. Allows setting the
shared-RAM size in compatibility modes in a card services environment.
