Latitude D600 BIOS

Anyone know where to get an unlocked set of BIOS?

I have a few issues with ram speed, clocking and cpu settings

Currently the base setup is OE w/1.4 ghz Intel 738 cpu w/400 bus.

From what I have learned so far is this;

Chipset, Intel 855PM
http://www.intel.com/products/notebook/chipsets/855pm/855pm-overview.htm

"Support for up to 2 GB of DDR 333/266/200 memory"

I have (2) 1gig PC2700's installed but the machine is running them at 266 not 333.

I recentlly bought an Intel 765 2.1ghz cpu w/400 bus.

What is it going to take to get this thing to run at full speed?

BTW, Is it possable to install some DDR400 PC3200 ram and get the chipset to run the ram at full bus speed? (Figuring on cpu bus of 400 and ram of 400)

Any help would be greatly appreciated...
Thanks.
