BASEDEV device drivers must be located in the directory
specified in step 1.
6. Save the CONFIG.SYS file, exit the text editor, shutdown the
system, and reboot to activate the changes.
7.2 Configurations
The SPP-100 Client Driver supports a limited set of configurations. These
choices have been made to maintain maximum compatibility with the
standard OS/2 parallel port device driver.
Configuration 1 : LPT2 at base address 378H
Configuration 2 : LPT3 at base address 278H
The client driver tries configuration 1 first, then configuration 2. If neither
configuration is available, the SPP-100 is left unconfigured.
7.2.1 Configuration Notes
1. The client driver examines the BIOS equipment list during boot
to see how many non-PCMCIA parallel ports are already
installed.
2. A configuration will fail if the port (LPT2 or LPT3) already
exists in the system or if Card Services reports the address
range already in use.
3. The client driver will not attempt to configure an SPP-100 for
LPT1.
4. The addresses used for LPT2 (378H) and LPT3 (278H) cannot be
changed.
5. On a card removal , the client driver will unconfigure the
SPP-100 and make the resources it was using available for any
device.
6. The use of interrupts (IRQs) varies according to the version of
OS/2 being used. See the section labeled "Interrupts for the
SPP-100 Under OS/2" for more information.
