Some (many) 64-bit processors have 32-bit compatibility modes. And most mainboards support multiple processors. Mainboard BIOSes for boards that support such processors have to be able to be configured for all the processors they support. Since there's no one-size-fits-all approach to this issue if both 64 and non-PAE 32-bit chips or operating system can be used, they make it a BIOS configuration option. So you, as the person who knows what processor, how much RAM and what OS are being used, must take this information and choose a suitable setting for those BIOS options. > Regards > Frank Randall Schulz -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
