B&B Electronics SPP-100 - Manual User Manual

Page 14

In example 5, three command line arguments are provided. The Client
Driver will first attempt to configure an SPP-100 inserted into any socket
with a base address of 3BCH and IRQ 5. If address 3BCH or IRQ 5 is
unavailable, the Client Driver will proceed to the second command line
argument and attempt to configure the card with a base address assigned
by Card and Socket Services and IRQ 10. If IRQ 10 is also unavailable, the
Client Driver will proceed to the third command line argument and
configure the SPP-100 with a base address and an IRQ assigned by Card
and Socket Services. If successfully configured, the SPP-100 will operate
as a standard printer port and the BIOS equipment list will not be
updated.

2.1.2.6 Example 6

DEVICE = C:\SPP-100\SPP100CL.SYS (b3BC,i5) ( ) (i10)

In example 6, the three command line arguments of example 5 have been
rearranged. The Client Driver will first attempt to configure a SPP-100
inserted into any socket with a base address of 3BCH and IRQ 5. If
address 3BCH or IRQ 5 is unavailable, the Client Driver will proceed to
the second command line argument and attempt to configure the card
with a base address and IRQ assigned by Card and Socket Services. Since
the second command line argument includes all available address and all
available IRQ resources, the third command line argument will never be
reached by the Client Driver. It is the user's responsibility to place the
command line arguments in a logical order.

2.1.2.7 Example 7

DEVICE = C:\SPP-100\SPP100CL.SYS (s0,b378,i7) (s1,b278,i5)

The type of configuration shown in example 7 may be desirable in
systems where more than one SPP-100 is to be installed. In this example,
the Client Driver will attempt to configure an SPP-100 inserted into socket
0 with a base address of 378H and IRQ 7. If the SPP-100 is inserted into
socket 1, the Client Driver will attempt to configure it with base address
278H and IRQ 5. This allows the user to force the SPP-100's address and
IRQ settings to be socket specific which may simplify cable connections
and software development. As in the previous examples, however, if the
requested address or interrupt resources are not available, the SPP-100
will not be configured.
