Quatech DSP-100, User Manual

Page: 11 / 40

2.1.2.6 Example 6
DEVICE = C:\DSP-100\DSP130CL.SYS (b300,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 DSP-100 inserted into any socket with a base address of
300H and IRQ 5. If address 300H 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 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:\DSP-100\DSP130CL.SYS (s0,b300,i5) (s1,b340,i10)
The type of configuration shown in example 7 may be desirable in systems where more than one
DSP-100 is to be installed. In this example, the Client Driver will attempt to configure a
DSP-100 inserted into socket 0 with a base address of 300H and IRQ 5. If the DSP-100 is
inserted into socket 1, the Client Driver will attempt to configure it with base address 340H and
IRQ 10. This allows the user to force the DSP-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 DSP-100
will not be configured.
2.1.3 Common Problems
Generic Client Drivers:
Many Card and Socket Services packages include a generic client driver (or SuperClient) which
configures standard I/O devices. If one of these generic client drivers is installed, it may
configure the DSP-100 causing the DSP-100 client driver to fail installation. In these cases, the
user should do one of the following:
1. Modify the operation of the generic client driver to disable the configuration of
modem/serial port cards. Consult the Card and Socket Services documentation for
availability and details of this feature.
2. Place the DSP-100 client driver before the generic client driver in the CONFIG.SYS.
