2.2IOP-241 Enabler for DOS
For systems that are not operating PCMCIA Card and Socket Services software, the IOP-241 DOS Enabler may be used to enable and configure the card. This Enabler, IOP241EN.EXE, will operate on any DOS system using an Intel 82365SL or PCIC compatible PCMCIA host adapter including the Cirrus Logic CL-PD6710/6720, the VLSI VL82C146 and the Vadem VG-365.
IMPORTANT:
In order to use the IOP-241 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 IOP-241 Enabler may interfere with its operation and with the device(s) it controls.
The IOP-241 Enabler does not support automatic configuration of adapters upon insertion, more commonly referred to as "Hot Swapping". This means the card must be installed in one of the system's PCMCIA sockets before executing IOP241EN.EXE. If more than one card is installed in a system, the Enabler must be executed separately for each card. Furthermore, IOP241EN.EXE should be executed to release the resources used by the card before it is removed from the PCMCIA socket. Since PCMCIA adapters do not retain their configuration after removal, any card that is removed from the system must be reconfigured with the Enabler after re-insertion into a PCMCIA socket.
IMPORTANT:
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.
