DOS\CSAMPLES:
A subdirectory of [CARDNAME] that contains "C" samples.
Win32\language:
Subdirectories containing samples for Win95/98/2000 and NT.
ACCES32
This directory contains the Windows 95/98/2000/NT driver used to provide access to the
hardware registers when writing 32-bit Windows software. Several samples are provided
in a variety of languages to demonstrate how to use this driver. The DLL provides four
functions (InPortB, OutPortB, InPort, and OutPort) to access the hardware.
This directory also contains the device driver for Windows NT, ACCESNT.SYS. This
device driver provides register-level hardware access in Windows NT. Two methods of
using the driver are available, through ACCES32.DLL (recommended) and through the
DeviceIOControl handles provided by ACCESNT.SYS (slightly faster).
SAMPLES
Samples for using ACCES32.DLL are provided in this directory. Using this DLL not only
makes the hardware programming easier (MUCH easier), but also one source file can be
used for both Windows 95/98/2000 and WindowsNT. One executable can run under both
operating systems and still have full access to the hardware registers. The DLL is used
exactly like any other DLL, so it is compatible with any language capable of using 32-bit
DLLs. Consult the manuals provided with your language's compiler for information on
using DLLs in your specific environment.
VBACCES
This directory contains sixteen-bit DLL drivers for use with Visual BASIC 3.0 and
Windows 3.1 only. These drivers provide four functions, similar to the ACCES32.DLL.
However, this DLL is only compatible with 16-bit executables. Migration from 16-bit to
32-bit is simplified because of the similarity between VBACCES and ACCES32.
PCI
This directory contains PCI-bus specific programs and information. If you are not using a
PCI card, this directory will not be installed.
SOURCE
A utility program is provided with source code you can use to determine allocated
resources at run-time from your own programs in DOS.
PCIFind.exe
A utility for DOS and Windows to determine what base addresses and IRQs are allocated
to installed PCI cards. This program runs two versions, depending on the operating
system. Windows 95/98/2000/NT displays a GUI interface, and modifies the registry.
When run from DOS or Windows3.x, a text interface is used. For information about the
format of the registry key, consult the card-specific samples provided with the hardware.
In Windows NT, NTioPCI.SYS runs each time the computer is booted, thereby refreshing
the registry as PCI hardware is added or removed. In Windows 95/98/2000/NT
