A. Verify that a block of memory for use by the PRO/100 PC Card has
been excluded from any memory manager being loaded. Memory manag-
ers are generally loaded in the CONFIG.SYS. The following example is
given for EMM386.EXE and a PRO/100 PC Card loading at its default
memory address of D2000:
DEVICE=C:\PATH\EMM386.EXE NOEMS X=D200-D3FF
B. Verify that power management has been disabled and the PCMCIA
socket is powered/enabled in the computer systems CMOS setup. These
settings may not be present in all machines. Consult your computer
documentation for information on how to access and modify the system
setup.
C. Reboot the machine by turning off the power and turning it back on
again (cold boot). If the driver still fails to load, the cause is generally a
resource conflict. Common causes of resource conflicts include sound
systems, other PCMCIA adapters, and built in ROMs. The resources
required for a PRO/100 PC Card include a memory window (MEM
keyword), a LAN interrupt (INT keyword, and an I/O address
(IOADDRESS keyword). The default settings are indicated below.
Review your computer documentation to determine what resources are
available, or use a trial and error approach. The table below shows a
suggested trial and error sequence. If you use this method, be sure to add a
memory exclusion from C000-DFFF to the EMM386 line until a suitable
memory location has been found. Then the memory exclusion can be
reduced to an 8K window. Perform a cold boot between each trial to
ensure that the PRO/100 PC Card and PC Card sockets are completely
reset.
When the PRO/100 PC Card driver is loaded it either reads a configura-
tion file or uses command line parameters to determine which resources it
should use. The following is a list of driver types, driver file names, and
the configuration method used by each:
