The page Vgamp.sys is a short article on something that should have a lot more information written on it.
If you know anything else about it, you are STRONGLY encouraged to add the information in. If you are unsure of proper formatting or style, add it to the talk page or this page itself as you think best and others will help.
Vgamp.sys is the standard VGA driver. It supports a standard resolution of 640x480x4 (4 bit = 16 colors). Its presence is necessary at all times, for emergency debug fallback. ReactOS can also support the VESA BIOS Extensions (VBE) driver (vbemp.sys), as well as native drivers that are designed by the video card manufacturer.
