2.2.1.5 Example 5DSP130EN.EXE (o1,i5,b340,s1)In example 2, the Enabler will configure the DSP-100 in socket 1 with a base address of 340Hand IRQ 5 using a configuration memory window at segment D000.2.2.1.6 Example 6DSP130EN.EXE (s0,b300,i5,r)In example 6, the Enabler will release the configuration used by the DSP-100 in socket 0 using aconfiguration memory window at segment D000. The base address and IRQ parameters areignored and may be omitted.2.2.1.7 Example 7DSP130EN.EXE (s1,r,wcc)In example 7, the Enabler will release the configuration used by the DSP-100 in socket 1 using aconfiguration memory window at segment CC00.2.2.2 Common ProblemsMemory Range Exclusion:The Enabler requires a region of high DOS memory when configuring a DSP-100. This region is1000H bytes (4KB) long and by default begins at address D0000H (the default address may bechanged using the "W" option). If a memory manager such as EMM386, QEMM, or 386Max isinstalled on the system, this region of DOS memory must be excluded from the memorymanager's control. Consult the documentation provided with the memory manager software forinstructions on how to exclude this memory region.Furthermore, some systems use the high memory area for BIOS shadowing to improve overallsystem performance. In order for the Enabler to operate, any BIOS shadowing must be disabledin the address range specified for the configuration window. BIOS shadowing can usually bedisabled through the system's CMOS setup utility.Socket Numbers:The Enabler requires the DSP-100's socket number to be specified on the command line and theDSP-100 must be inserted into the socket before the Enabler is invoked. Some vendors numbertheir sockets from 1 to N while other vendors number their sockets from 0 to N-1. For theDSP-100 Enabler, the lowest socket number in the system is designated socket 0.DOS/Windows 3.x 2-10
