Example 4 DEVICE = C:\DAQPA_EN.EXE (s0,b300,i5,wCC)
Here the Enabler will configure the DAQP card in socket 0 with a base address at 300H and IRQ level 5 using a configuration memory window at CC000H.
Example 5 | DEVICE = C:\DAQPA_EN.EXE | (s0,r) |
| DEVICE = C:\DAQPA_EN.EXE | (s0,r,b300,i5) |
These two command line arguments are equivalent because of the “r” option. The Enabler will release the configuration used by the DAQP card in socket 0 using a configuration memory window at D0000H.
Example 6 DEVICE = C:\DAQPA_EN.EXE (s0,r,wC8)
Here the Enabler will release the configuration used by the DAQP card in socket 1, using a configuration memory window at C8000H.
2.4.2.3 Common Problems
Memory Range Exclusion
The Enabler requires a region of high DOS memory when configuring a DAQP card. This region is 1000H (4096) bytes long and by default begins at address D0000H (this default address can be changed by using the “w” option).
If a memory manager such as EMM386, QEMM or 386MAX is installed on the system, this region of DOS memory must be excluded from the memory manager’s control (normally by using the “x” switch). Consult the documentation provided with the memory manager software for instructions on how to exclude this memory region.
Furthermore, some systems use the high memory area for ROM shadowing to improve overall system performance. For the Enabler to properly operate, any ROM shadowing must be disabled in the address range specified for the configuration window. This can usually be completed by using the system’s CMOS setup utility.
Socket Numbers
The Enabler requires that the socket number be specified for the DAQP card to be configured. The DAQP card must be inserted into the socket before executing the Enabler.
For the DAQP series Enabler, the lowest socket number is always designated as socket 0 and the highest socket number as
Card and Socket Services Software
In order to use DAQP series Enabler for DOS, the system must NOT be configured with Card and Socket Services software. If Card and Socket Services software is installed, the Enabler may interfere with its operation and the devices it controls.
