2.2.2 Common Problems
Memory Range Exclusion:
The Enabler requires a region of high DOS memory when configuring a
SPP-100. 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.
Socket Numbers:
The Enabler requires the SPP-100's socket number to be specified on the
command line and the SPP-100 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 SPP-100
Enabler, the lowest socket number in the system is designated socket 0.
Card and Socket Services Software:
In order to use the SPP-100 Enabler for DOS, the system MUST NOT be
configured with Card and Socket Services software. If a Card and Socket
Services software is installed, the SPP-100 Enabler may interfere with its
operation and with the device(s) it controls. For systems configured with
Card and Socket Services, the SPP-100 Client Driver is the recommended
method of configuration.
