You need to get the BIOS update from your motherboard manufacturer  
(if they're still around).  I doubt that you will find a BIOS that  
will support that size drive though.  You might get to 8.4 or 32 GB.

The motherboard manufacturer will usually provide a bootdisk that  
will flash the BIOS.  Sometimes, they provide a way to back out of  
the update, most of the time they don't.  Personally, I've never had  
a problem with updating BIOSes, but there's always a first time.  You  
will most likely have to find a windows (or even DOS) machine to  
create the BIOS bootdisk.

http://www.pcmech.com/show/bios/81/  has a decent howto explaining  
the possible pitfalls (and other options).
