readme.txt - 20-Nov-1997
This document describes how to install under Windows 95 the ComputerEyes/PCI
drivers for use with the ComputerEyes/PCI frame grabber.
This disk contains the following files:
readme.txt This file
h20drv.dll Hardware interface library
ctdmamem.dll DMA interface library
vdmamemd.vxd Virtual DMA buffer driver (Windows 95)
cepcivid.drv Video for Windows capture driver
mcidvpci.drv MCI Video Overlay driver
mciovly.doc Documentation for MCI Video Overlay driver
cepci.dll Interface library
cepci32.dll 32-bit interface library
cepci40.dll Thunking interface library
dv_cepci.vxd Configuration Manager Handler and interrupt handler
It also contains the following files for the TWAIN interface:
twain.dll
twain_32.dll
twunk_16.exe
twunk_32.exe
dvptwn32.ds
If the ComputerEyes/PCI is being installed for the first time the hardware
setup and installation of related drivers will be performed by way of the
Plug and Play interface.
The drivers can be updated for a previously installed ComputerEyes/PCI as
follows:
Under Settings->
Control Panel->
System->
Device Manager->
Sound, video and game controllers->
ComputerEyes/PCI Video Capture->
Properties->
Driver
select 'Change Driver' and 'Have Disk'. Then select this disk and
the new drivers will be installed.
When the setup is complete the following files will have been copied
to their corresponding directories as follows:
Windows system directory (usually C:\WINDOWS\SYSTEM):
h20drv.dll
ctdmamem.dll
vdmamemd.vxd
cepcivid.drv
dv_cepci.vxd
Windows directory (usually C:\WINDOWS):
twain.dll
twain_32.dll
twunk_16.exe
twunk_32.exe
Windows 32-bit TWAIN directory (\TWAIN_32 under the Windows directory):
dvptwn32.ds
The SYSTEM.INI in the windows directory will be updated as follows:
new section [VDMAMemD] and the following entry is added:
NumberOfPages=303
(this entry allocates that number of pages of 4096 bytes of contiguous
memory to be used for DMA from the board. The number 303 will be
enough for a full 640x480x24 RGB image. If this uses too much memory,
a value of 134 will allow you to capture 320x240x24 RGB frames.
Changing this value to 380 will allow you to capture a 640x480x32
RGB image.)
the following entry is added to the [MCI] section:
Overlay=mcidvpci.drv
After making all of the above changes, windows should be restarted to
enable the allocation of the DMA buffer.
At this point you can run ComputerEyes(WEPCI.EXE), CineMaker(WINCINE.EXE)
or any other Video for Windows compatible application.
