i have 1.04G with BIOS 2004

when i boot i got New CPU Installed message press F1 to enter setup F2 to load default values and continue this happens very often
my first conclusion was the bios battery is weakened but when i entered the bios setup nothing change, they all set the way i set them, than i save the bios and exit. sometimes the new cpu installed message gone and more often i have to enter bios setup and exit and save changes many many times
finally after reading the user's manual i found a bios setup option in Boot > Boot Settings Configuration > Wait For "F1" If Error > Disabled
with that oiption disabled new cpu installed message still appear but doesn't wait for me to press anything, and continues entering windows xp

unfortunately my PC2-6400 4x1GB PNY RAM is detected as PC2-5300, and i need to manually put DDR2-800 in Advanced > Jumperfree Configuration > DRAM Frequency
so my workaround still has flaw, i managed entering windows but with PC2-5300

and for the last problem in ASUS website faq it said to use 4GB ram i need to enable memory remap feature in Advanced > Chip Configuration > Memory Remap Featured
i can't seems to find that option in BIOS setup and the BIOS only read 3200MB ram
and i'm using P4 631 if that matters

any comments would be much appreciated
