"The BIOS supports 48-bit Logical Block Addressing (LBA) and Extended Cylinder Head Sector(ECHS) translation modes."
from intel.com
In short, very large drives are supported with the current BIOS. I'll leave you to research 48 BIT LBA and what IDE drives that can be had today.

I have a nine year old computer running on Windows XP Pro Service Pack 3. The main board is an Intel D845GRG. The HD is 115 GB. Will this main board support a higher capacity HD? If so, how high can I go? Thanks!
