Problems with DirectX and some 3Dfx based cards
===============================================

Some problems may occur when using 3Dfx based 3D
accelerated cards as a secondary card if the primary
display card (Your 2D card) also has some 3D acceleration.

When you run Flying Corps, if you find that on the graphics 
driver selection screen only 'Rowan Software Driver' and 
'Direct3D Hardware Driver' are listed and that the Direct3D 
hardware driver option has been greyed out then this means 
that your 3Dfx card has not been installed successfully.

This problem occurs when the 3Dfx card has not been correctly 
registered by Windows 95. The solution is to re-install your cards drivers. 
The following test can be used to check
whether your card has been installed correctly.

From the windows 95 desktop click on the 'Start' menu item
and select 'Run'. In the 'Run' dialog type 'regedit'
and select 'OK'. This will launch the windows 95 registry 
editor. The display in the lefthand window should look 
something like the diagram below.

[-]----My Computer
    |
   [+]-HKEY_CLASSES_ROOT
    |
   [+]-HKEY_CURRENT_USER
    |
   [+]-HKEY_LOCAL_MACHINE
    |
   [+]-HKEY_USERS
    |
   [+]-HKEY_CURRENT_CONFIG
    |
   [+]-HKEY_DYN_DATA

Click on the '+' next to HKEY_LOCAL_MACHINE. Your display should now
look something like the following diagram.

    |
   [+]-HKEY_CLASSES_ROOT
    |
   [+]-HKEY_CURRENT_USER
    |
   [-]-HKEY_LOCAL_MACHINE
    |  |
    | [+]-Config
    |  |
    | [+]-Enum
    |  |
    | [+]-hardware
    |  |
    | [+]-SOFTWARE
    |  |
    | [+]-System
    |
   [+]-HKEY_USERS
    |
   [+]-HKEY_CURRENT_CONFIG
    |
   [+]-HKEY_DYN_DATA

Now click on the '+' next to 'hardware'. Your display should now
look something like the following diagram.

[-]----My Computer
    |
   [+]-HKEY_CLASSES_ROOT
    |
   [+]-HKEY_CURRENT_USER
    |
   [-]-HKEY_LOCAL_MACHINE
    |  |
    | [+]-Config
    |  |
    | [+]-Enum
    |  |
    | [-]-hardware
    |  |  |
    |  | [+]-DESCRIPTION
    |  |  |
    |  | [+]-devicemap
    |  |  |
    |  | [+]-DirectDrawDrivers
    |  |
    | [+]-SOFTWARE
    |  |
    | [+]-System
    |
   [+]-HKEY_USERS
    |
   [+]-HKEY_CURRENT_CONFIG
    |
   [+]-HKEY_DYN_DATA

If at this stage, the 'DirectDrawDrivers' entry has not been displayed
then your card has not been setup correctly. If it is present but you 
are still experiencing problems then continue with the remaining checks
below.

Click on the '+' next to DirectDrawDrivers. The display should change
to look something like the diagram below.

[-]----My Computer
    |
   [+]-HKEY_CLASSES_ROOT
    |
   [+]-HKEY_CURRENT_USER
    |
   [-]-HKEY_LOCAL_MACHINE
    |  |
    | [+]-Config
    |  |
    | [+]-Enum
    |  |
    | [-]-hardware
    |  |  |
    |  | [+]-DESCRIPTION
    |  |  |
    |  | [+]-devicemap
    |  |  |
    |  | [-]-DirectDrawDrivers
    |  |     |
    |  |     []-aba52f41-f744-11cf-b4-52-00-00-1d-1b-41-26
    |  |
    | [+]-SOFTWARE
    |  |
    | [+]-System
    |
   [+]-HKEY_USERS
    |
   [+]-HKEY_CURRENT_CONFIG
    |
   [+]-HKEY_DYN_DATA

Double clicking on the string of characters under the
'DirectDrawDrivers' entry should cause a description
string and driver name to be displayed in the right hand
window. If this does not match the name of your card
then you do not have the cards drivers installed correctly.

If after attempting to re-install your card's Direct3D drivers
you still cannot find your card's details in the registry as defined
above then we suggest that you contact
your card's manufacturer for technical support.
