[optimus111]

Hi, I have A Msi megabook S262 with bios 7.08 the lastone that i,ve found The specifications said that the Max memory are 2 gb, but i can plug 2 sticks of 2 gb each and the system boots but the bios only recognize 2936 mb, it has a 945 gm chipset. So its posible mod the bios to force it to recognize the 4096 mb. Thnak you and congratulatios for the web.
