2.1.2.4 Example 4 DEVICE = C:\IOP241CL.SYS (i11,b300)

A single command line argument is provided. Because the parameter order is not significant, the Client Driver will attempt to configure an IOP-241 inserted into any socket with a base address of 300H and IRQ 11. If address 300H or IRQ 11 are unavailable, the IOP-241 will not be configured.

2.1.2.5 Example 5 DEVICE = C:\IOP241CL.SYS (b300,i5) (i10) ( )

Three command line arguments are provided. The Client Driver will first attempt to configure an IOP-241 inserted into any socket with a base address of 300H and IRQ5. If address 300H or IRQ 5 are 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 attempt to configure the IOP-241 with a base address and an IRQ assigned by Card and Socket Services.

2.1.2.6 Example 6 DEVICE = C:\IOP241CL.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 an IOP-241 inserted into any socket with a base address of 300H and IRQ 5. If address 300H or IRQ 5 are 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. The user must ensure the command line arguments are placed in a logical order.

2.1.2.7 Example 7

DEVICE = C:\IOP241CL.SYS (s0,b300,i5) (s1,b340,i10)

The type of configuration shown in example 7 may be desirable in systems where more than one IOP-241 is to be installed. In this example, the Client Driver will attempt to configure an IOP-241 inserted into socket 0 with a base address of 300H and IRQ 5. If the IOP-241 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 IOP-241'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 IOP-241 will not be configured.
