Sets ISA Idle time to 200 ns instead of default 100 ns. Does lower system
performance.
# systems.
#IsaReadActive 4
#IsaWriteActive 4
Sets active period of ISA Read and Write signals in 50 ns increments. Do not
use unless you are feeling brave." Driver is currently tuned for 25 MHz HHC
Please note again that none of these settings is necessary for PKODI.COM to
run; the Link driver," line however, must be present. Also note that the NODE
ADDRESS setting can be dangerous since using it could cause two machines on
the network to have the same Ethernet ID.
Advanced Power Management BIOS
The APM specification makes available a set of OEMĆdefined extensions that can
be used for communicating with the BIOS. PKODI uses an OEM extension,
defined by Intermec Technologies Corporation, to read the Ethernet ID from the
hardware.
The APM BIOS may be resident in the computer's system BIOS or it may be
provided separately as a DOS TSR, which is NORAPM.EXE. When the APM
BIOS is provided as a DOS TSR, be sure that the APM BIOS is loaded before
PKODI.COM is loaded; otherwise, PKODI does not read its Ethernet ID and
fails the installation.
If testing must be done without the APM BIOS, add a
node address
setting to
NET.CFG to provide an Ethernet ID, as shown in the preceding example. Note
the warning given earlier about using the NODE ADDRESS" setting.
Warning for Prototype PEN*KEY Units
PEN*KEY prototype units did not contain a complete Norand Ethernet physical
address; consequently, PKODI.COM synthesizes an address by prepending the
Norand Ethernet prefix bytes to the serial number embedded in the prototype.
There is a slight possibility that the Ethernet address synthesized by PKODI
could be identical with the Ethernet address from a production PEN*KEY HHC.
PEN*KEY prototypes should therefore not be mixed with production PEN*KEY
units on the same Ethernet segment.
If prototype and production units must be mixed on an Ethernet segment, all
Ethernet addresses should be recorded and compared to ensure that duplicate
addresses do not exist. PKODI displays the physical Ethernet address used
when it loads.
