The VPBs are programmed via the VPB Application Programmer Interface, a set of C callable functions provided as a Windows 32 bit DLL (Windows NT), or a library (Linux & FreeBSD) . This will be referred to as the VPBAPI, or just API.
This document was originally written as a Windows Help file, and is in the process of being converted to HTML. Tasks remaining include:
Each VPB4 or VPB8L card requires 4 consecutive I/O port address, defined by the base address. Each V4PCI card requires a block of 128k bytes of memory. None of the VPB models require any interrupts or DMA channels.
2. Follow instructions in README to compile and install.
2. Go to the Start Toolbar and click on Run.
3. To run the install program with its default settings type a:\install and click OK. This copies the installation files from drive a:\ to c:\vpb. Otherwise type a:\install [destination path source path] and click OK. For example, typing a:\install k:\vpb\ a:\ copies the installation files from a floppy disk in drive a:\ to the subdirectory k:\vpb.
4. Proceed to Setting the Base Address under Windows NT to set the VPB base address.
2. Start Regedit, which is in the Windows NT directory.
3. Navigate the registry to the key HKEY_LOCAL_MACHINE, System, CurrentControlSet, Services, vpb.
4. Under the vpb key will be one or more subkey. Each subkey represents a VPB. If this is the initial installation there will be a single subkey ‘0000’. Click on this subkey.
5. Double clicking on the base entry will allow the base address of the VPB to be changed. The legal base addresses are listed in the hardware installation section.
6. Note the base address, as this is required for the hardware installation.
2. It is possible to damage the VPB by exposure to static electricity. To prevent any buildup of static electricity, touch the chassis of the PC before handling the VPB. Minimise contact with the VPB, and try to touch only the edges of the board.
3. Remove the VPB from its anti-static bag and lay it on the anti-static bag.
4. The VPB base address is set via a small DIPswitch mounted in the middle of the top edge of the card. Note the number under each switch and the direction marked ON.
5. VPB4 & VPB8L Only: Set the DIP switch using the
base address from the software installation as follows:
|

DIP 1 | DIP 2 | DIP 3 | DIP 4 | |

6. VPB4 & VPB8L Only: Install the VPB in a suitable ISA slot (AT bus slot), replace the PC’s case, and reboot.
7. V4PCI Only: Install the VPB in a suitable PCI slot, replace the PC’s case, and reboot.
8. The VPB is now ready for use.
2. Navigate the registry to the key HKEY_LOCAL_MACHINE, System, CurrentControlSet, Services, vpb.
3. Under the vpb key will be one or more subkey. Each subkey represents a VPB card. If this is the initial installation there will be a single subkey ‘0000’. Additional subkeys indicate additional VPBs installed, one subkey for each VPB.
4. Click on the vpb key to highlight it.
5. From the Edit menu select New-key. A new key will appear. Rename this key. It is recommended that sequential numbers (e.g. 0001, 0002, …., ) be used for successive cards.
6. Click on the new key to highlight it.
7. From the Edit menu select New-DWORD value.
8. Type the word "base" into the highlighted area.
9. Modify the base value to the desired base address using Modify from the Edit menu.
10. Shut down the PC and install the new VPB hardware.
2. Navigate the registry to the key HKEY_LOCAL_MACHINE, System, CurrentControlSet, Services, vpb.
3. Under the vpb key will be one or more subkey. Each subkey represents a VPB card. If this is the initial installation there will be a single subkey ‘0000’. Additional subkeys indicate additional VPBs installed, one subkey for each VPB.
4. Click on the subkey you would like to remove.
5. Select Delete from the Edit menu.
6. Shut down the PC and remove the VPB.
Note
The VPB may be left in the PC even though it is not recognised
by the VPB software. This will not hinder operation of the PC or the remaining
VPBs.
