CHAPTER 5: Utility Software
When Card Services is selected, the PCDD5250.SYS device driver must be loaded
via your CONFIG.SYS file, as instructed by the installation program.
Note that using Card Services with any of the “Values Assigned by” selections is
preferable to using any of the hardware-specific selections, as the use of Card
Services is more likely to avoid configuration conflicts.
If your system does not have Card Services, then one of the hardware controllers
should be selected. These selections directly control the hardware of the PC Card
sockets. It is important to remember that the configuration of the base I/O port
address, memory segment address interrupt level, and socket are now your
responsibility. You must make the proper selections for these items on the
Hardware menu when using a hardware controller. The enabler program currently
supports the IBM ThinkPad
®
, Intel
®
82365 PCIC, Sharp
®
PHIC, and Toshiba
®
ICCCNT controllers.
The Intel selection should be used if your system is using the Intel 82365 or
compatible controller. Many systems use this controller; try it if you are unsure
which controller supports the 67XX/68X series laptop systems. The Toshiba
controller is found in the 45XX series laptop systems. Newer Toshiba laptops use
an Intel compatible controller.
Base I/O Address
The Base I/O Address item on the Hardware menu allows the selection of the base
port address to be used by the Adapter Card. The default value is 2718 or 0118,
depending on which 5250 adapter you are using. The 5250 Adapter will use eight
I/O port addresses starting with the listed addresses (for example, 2718-271F hex).
On the 5250 ISA Adapter Card only, the selected address must match the switch
settings. Refer to the address list in the online help.
NOTE
This menu item is inaccessible if Card Services is used as the PC Card
Controller and the values are to be assigned by Card Services or the
Enabler.
Segment Address
The Segment Address item on the Hardware menu allows the selection of an 8-KB
memory segment to be used by the Adapter. The default value is DC00 hex. If an
extended memory manager is in use, you may need to exclude the segment to be
used by the Adapter from that managed by the manager. The software will display
possible memory conflicts.
