In terms of file redistribution, the BeOS platform behaves practically the
same as the DOS platform. Read section chapter "Dos specifics" in the manual
to learn more about this.

BeOS Allegro supports the following card parameters for the
set_gfx_mode() function:
<ul><li>
GFX_TEXT<br>
This closes any graphics mode previously opened with set_gfx_mode.
<li>
GFX_AUTODETECT<br>
Let Allegro pick an appropriate graphics driver.
<li>
GFX_AUTODETECT_FULLSCREEN<br>
Autodetects a graphics driver, but will only use fullscreen drivers,
failing if these are not available on current platform.
<li>
GFX_AUTODETECT_WINDOWED<br>
Same as above, but uses only windowed drivers.
<li>
GFX_SAFE<br>
Special driver for when you want to reliably set a graphics mode and
don't really care what resolution. See the set_gfx_mode()
documentation for details.
<li>
GFX_BWINDOWSCREEN_ACCEL<br>
Fullscreen exclusive mode. Supports only resolutions higher or equal
to 640x480, and uses hardware acceleration if available.
<li>
GFX_BWINDOWSCREEN<br>
Works the same as GFX_BWINDOWSCREEN_ACCEL, but disables acceleration.
<li>
GFX_BDIRECTWINDOW<br>
Fast windowed mode using the BDirectWindow class. Not all graphics
cards support this.
<li>
GFX_BWINDOW<br>
Normal windowed mode using the BWindow class. Slow but always works.
<li>
GFX_BWINDOW_OVERLAY<br>
Fullscreen mode using BWindow with a BBitmap overlay. This mode isn't
supported by all graphics cards, only supports 15, 16 and 32-bit color
depths, but allows any fullscreen resolution, even low ones that are
normally unavailable under BeOS.
</ul>
