ATOMBIOS.SYS v0.86 -- widescreen patch driver    2010-03-07    rlalla@stepnet.de
--------------------------------------------------------------------------------

Requirements:
 - ATI/AMD graphics chipset
 - ATOM-Bios (original pre-2008 style, or new DTD based style) 
 - Intel cpu with Intel 9xx or G3x/P3x or G4x/P4x or i3000 or i4500 chipset
   -or- Intel Core i3/i5/i7 cpu with any chipset 
   -or- AMD64 cpu with any mainboard chipset

Installation:
 - CONFIG.SYS: basedev=atombios.sys
        -or-   basedev=atombios.sys +HHHHVVVV
 - Read startup message at reboot

What screen modes does it replace:
   No option specified in CONFIG.SYS
     - mode_EE 1856x1392 --> 1280x800
     - mode_EF 1920x1440 --> 1440x900
     - mode_EB 1400x1050 --> 1680x1050
   Option +HHHHVVVV specified in CONFIG.SYS (custom resolution)
     - mode_EE 1856x1392 --> HHHHxVVVV 

Notes about custom resolution:
 - Custom resolution must be specified as 4 decimal digits each, 
   like +10240600 for 1024x600 resolution
 - Horizontal resolution will be rounded down to the next multiple of 8
 - Supported horizontal resolution range is 512..2048
 - Supported vertical resolution range is 320..1536
 - Not all resolutions might be supported by your graphics card and screen 
 - Scitech display driver will suppress any unexpected resolutions,
   so use Panorama or Gengradd driver instead.
 - Custom resolutions >1680 are using "DVI reduced" horizontal timings.

Permanent restriction:
 - Only resolutions smaller or equal to lcd resolution can be used.

Temporary restrictions:
 - Every graphics card manufacturer might arbitrarily modify the bios.
   In that case send me a copy of your bios to adapt the driver to your card.
 - Sync timings are based on simplified algorithms and are not exactly
   conforming to VESA specs. Most flat screens don't care about, 
   but compatibility with analog crt screens might be limited. 
 - Intel cpu with non-Intel chipset or older AMD cpu are not supported now.
   In case you need it, send me specs of the memory controller.
