Method for determining a Monitor's EDID information when the visual display is unavailable
Display monitors which only accept digital input are currently being introduced to the market. These monitors nominally communicate their capabilities to the host graphics card by means of the data within anExtended Display Identification Data (EDID) data block, a video standard standardized by the Video Electronics Standards Association (VESA).[*] When the EDID data is corrupt or unavailable, or the host graphics card is unable to find a video mode compatible with those described in the EDID, the host graphics card may not output any video signal and the user experiences a blank screen. If this situation occurs when an Operating System (OS) has already loaded, the OS typically makes provisions to allow loading other more generic graphics drivers, which will hopefully help in analyzing the problem. However, this problem is especially challenging when the initial boot up screens are not available, a situation in which the user may be clueless as to the cause or ways to proceed. A method is disclosed which allows for determining and analyzing the Monitor's EDID information when these initial boot up screens are unavailable.
Computers typically contain some form of removable read/write storage e.g. floppy disk. An uncomplicated OS to boot the computer can easily be loaded even on many of the smallest sizes of this medium. The OS need not ask for any user intervention to load. Once the OS is loaded, a program can be loaded by the boot pro...
