This is a list of frequently asked questions.

Q. Can regular DIVE-enabled applications benefit from WarpOverlay! ?
A.  No.  WarpOverlay! implement completely different API, so application must
be changed, to interact with WarpOverlay!

Q. What is architecture of WarpOverlay! ? How it designed?
A. WarpOverlay! currently consist of 3 files:
   1) vrammngr.dll - manager of on-card Video memory (VRAM);
   2) woverlay.dll - the set of HW-dependent drivers, which drive your video-
   card's hardware;
   3)  hwvideo.dll - API library, which interact with applications and handle
   some common tasks.

Q.  Is it possible to have two (or more) WarpOverlay!-accelerated windows at
time?
A.  No, this is impossible. Graphics chipsets usually support only one
overlay window, so WarpOverlay! designed only for one window at time.

Q.  I  am  software  developer.  How I can implement support for WarpOverlay!
within my application?
A.  You need WarpOverlay! SDK. It consists of needed header file and some
examples. Today SDK located at the:
 http://www.logicsystems.ru/elf/data/sdk.zip

Q. What is the targets of WarpOverlay! ?
A.  WarpOverlay!  primary  targeted for applications like video players. It
can  significally  reduce  CPU usage, because scaling and conversion from YUV
colorspace  (two  CPU-intensive  operations) are both handled by the graphics
hardware.

Q. How WarpOverlay! interact with display driver?
A.  WarpOverlay!  is  a GRADD-driver. It reside in the GRADD chain and handle
it's  own  set  of  commands.  It  also handle some specific situations (like
starting FS sessions). It does not affect any regular GUI functionality.

Q. Are support planned for XYZ-chip?
A. It's hard to answer in general. Support for specific chipset depend on the
availability  of documentation and sample hardware. So any specific chipset
need specific investigation. User's demand also very important.

Q. Who actually wrote WarpOverlay! ?
A. I am, Valery Gaynullin, the only one WarpOverlay! developer and owner. But
I got a lot of help from many different peoples (not only OS/2 users).
