Caution:
Pay careful attention when changing the registry entries. If an error
occurs while making these changes, the configurations can be
permanently damaged. This could render the Windows NT operating
system inoperable.
For simplicity, it is recommended that end users implement an
install/uninstall program, since all of these tasks are automated.
5.2.3 Application of the De vice Driver for Windows‘ 98
TM
and
Windows‘ 2000/XP
Similar to Windows‘ 95, the device driver allocates physical memory
for storing images. The driver also allows access to the
eGrabber-4plus’ register.
Reserving memory space is only possible with a device driver under
the Windows98/2000 operating systems.
The driver also transforms linear memory addresses into physical
memory addresses.
User programs do not have direct communication with the driver,
instead access is provided by DLLs.
Phytec’s installation disk is recommended for operation of the
Windows98/2000/XP driver with user specific applications.
These applications are located on the installation CD under the
PCIGRAB4\DRIVER\WIN2k_98 directory. Files from this directory
can be copied to a disk and applied to user applications.
