[FONT=Calibri][SIZE=3]What I did
[FONT=Calibri]1- [/FONT]I upgraded the BOIS from A04 to A07
[FONT=Calibri]2- [/FONT]I could not find an option for BOIS default setup
[FONT=Calibri]3- [/FONT]I removed the motherboard battery for about half an hour
[FONT=Calibri]4- [/FONT]I removed one of the RAM stick
[FONT=Calibri]5- [/FONT]I can access CMOS by pressing F2
[FONT=Calibri]6- [/FONT]I tried to eliminate the possibility of a hardware that caused the problem I removed CD rom drive and floppy drive but no luck.
