SP1 is supposed to give support automatically. If you're not into installing it though for some reason, I've also heard the following registry mod works :)

You'll need to enable "Large Drive Support" by editing the Registry. Expand the following branch...

HKEY_LOCAL_MACHINE | SYSTEM | CurrentControlSet | Services | atapi | Parameters

In the RH pane, you'll need to add a new DWORD called...

EnableBigLba...with a DWORD Value of 1

The following MSKB article describes the 137GB limitation, and how to enable 48-bit LBA in XP pre-SP1...

How to Enable 48-bit Logical Block Addressing Support for ATAPI Disk Drives in Windows XP

The above Registry edit enables support for drives larger than 137GB in W2K pre-SP3 and XP pre-SP1. It's needed anytime a HDD larger than 137GB is connected to the MB's ATA bus, regardless of any BIOS that supports 48-bit LBA. :)
