IMPORTANT:

In order to use the QSP-200/300 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 QSP-200/300 Enabler may interfere with its operation and with the device(s) it controls.

The QSP-200/300 Enabler does not support automatic configuration of adapters upon insertion, more commonly referred to as "Hot Swapping". This means the adapter must be installed in one of the system's PCMCIA sockets before executing QSP200EN.EXE. If more than one adapter is installed in a system, the Enabler must be executed separately for each adapter. Furthermore, QSP200EN.EXE should be executed to release the resources used by the adapter before it is removed from the PCMCIA socket. Since PCMCIA adapters do not retain their configuration after removal, any adapter that is removed from the system must be reconfigured with the Enabler after reinserting it into a PCMCIA socket.

IMPORTANT:

The Enabler requires a region of high DOS memory when configuring a QSP-200/300. 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.
