sur le site d'Award / Phoenix, j'ai trouvé ça :
What does this message mean: "Invalid System Configuration Data"?
Extended System Configuration Data (ESCD) provides a storage space for the configuration data in a Plug and Play system. In a "Plug and Play" (PnP) system, the BIOS (as well as the operating system, if it is PnP aware) needs to know what system resources - memory space, IO space, DMA channels and IRQs - are used by add-on cards. For cards which are not PnP, the BIOS has to be told by the computer user what resources are used by these cards. Once you have configured your system properly, ESCD is used to load the same configuration each time the computer boots. If this message is displayed, an error has occurred. Take these steps:
Go into Setup and find the field labeled, "Reset configuration data;"
Set this field to "yes;"
Save and exit the Setup program. The system restarts and clears ESCD during POST;
Run whatever Plug and Play configuration tool is appropriate for your system:
If you have Windows 95/98 (which are Plug-and-Play operating systems), simply restart your computer. Windows 95/98 will automatically configure your system and load ESCD with the new data.
If you don't have Windows 95/98, run the ICU (ISA Configuration Utility).
c'est plus ou moins ce que j'avais indiqué comme manip au début du topic. Essaye et dis ce que ça fait...
