Проверил, такой опции в BIOS нет. Как я понимаю, заработает ли 4Гб
сильно зависит от материнской платы. У меня Intel D945GNT. В BIOS в
разделе Advanced >> Chipset Configuration >> Memory Configuration
содержится следующая информация:
Total Memory: 4096 MB
Memory Mode : Dual Channel
Memory Channel A:
Slot 0: 1024 MB (DDR 667) SPD: 5.0-5-5-13
Slot 1: 1024 MB (DDR 667) SPD: 5.0-5-5-15
Memory Channel B:
Slot 0: 1024 MB (DDR 667) SPD: 5.0-5-5-13
Slot 1: 1024 MB (DDR 667) SPD: 5.0-5-5-15
Т.е., как я понимаю BIOS видит всю память правильно. А ядро Linux - нет.
