2.2.2.3 Example 3 | DEVICE = C:\IOP241EN.EXE (i10,b340,s1) |
The Enabler will configure the IOP-241 in socket 1 with a base address of 340H and IRQ 10 using a configuration memory window at segment D000. Note that the parameter order is not significant.
2.2.2.4 Example 4 | DEVICE = C:\IOP241EN.EXE (s0,b300,i3,wd8) |
The Enabler will configure the IOP-241 in socket 0 with a base address of 300H and IRQ 3 using a configuration memory window at segment D800.
2.2.2.5 Example 5 | DEVICE = C:\IOP241EN.EXE (s0,b300,i5,r) |
The Enabler will release the configuration used by the IOP-241 in socket 0 using a configuration memory window at segment D000. The base address and IRQ parameters are ignored and may be omitted.
2.2.2.6 Example 6 | DEVICE = C:\IOP241EN.EXE (s1,r,wcc) |
The Enabler will release the configuration used by the IOP-241 in socket 1 using a configuration memory window at segment CC00.
2.2.3Common Problems
2.2.3.1 Memory Range Exclusion
The Enabler requires a region of high DOS memory when configuring an IOP-241. This region is 1000H bytes (4KB) long and by default begins at address D0000H (the default address may be changed 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. 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 BIOS shadowing to improve overall system performance. In order for the Enabler to operate, any BIOS shadowing must be disabled in the address range specified for the configuration window. BIOS shadowing can usually be disabled through the system's CMOS setup utility.
2.2.3.2 Socket Numbers
The Enabler requires the IOP-241's socket number to be specified on the command line and the IOP-241 must be inserted into the socket before the Enabler is invoked. Some vendors number their sockets from 1 to N while other vendors number their sockets from 0 to N-1. For the IOP-241 Enabler, the lowest socket number in the system is designated socket 0.
