Most likely any bios version on the GX260 should support that drive.

Keep in mind that most OSes out-of-the-box don't support drives over 137GB (it will only see about 137GB and allow you to partition that and then when having applied hotfixes/service packs it will see the whole drive to allow you to partition the rest). I think that XP SP2 CDs may see the whole drive at the install time.

Only Special OEM Preinstall INF allows booting and formatting and installing 48 bit LBA Partitions.

By default, the original release version of Windows XP Home Edition and of Windows XP Professional do not have 48-bit LBA support. Your computer must meet the following requirements to use 48-bit LBA ATAPI support: • 48-bit LBA-compatible BIOS.
• 137-GB hard disk or larger.
• You must have Windows XP SP1 installed.
For the original release version of Windows XP Home Edition or of Windows XP Professional, you can enable 48-bit LBA for testing purposes. To do this, set the EnableBigLba registry value to 1 in the following registry subkey:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Atapi\Parameters\
Warning Data corruption may occur if either of the following conditions is true:

Its not really corruption.  The drive gets worse and worse and then DIES losing All data.

• You use this registry value to enable 48-bit LBA support in the original release version of Windows XP Home Edition or of Windows XP Professional.
• You install an earlier version of Windows on a disk partition that was previously created by a 48-bit aware operating system, such as Windows XP SP1. And that disk partition is equal to or larger than the current addressable limit of 137 GB.

Note The previous registry setting is ignored in Windows XP SP1 and later. If you try to enable the 48-bit LBA ATAPI support in the original release version of Windows XP Home Edition or of Windows XP Professional by editing the previous registry setting, and you did not meet the minimum requirements, the following issues may occur: • The registry value EnableBigLba is disabled. If you have a 48-bit compatible BIOS that can support a hard disk that has a capacity that is greater than 137 GB, only the first 137 GB of the hard disk are addressable. The rest of the hard disk is not used. 
• The registry value EnableBigLba is enabled, but you do not have a 48-bit LBA compatible BIOS and the capacity of the hard disk is not greater than 137 GB.

If you enable the 48-bit LBA ATAPI support by editing the registry setting, but you lack both a 48-bit LBA compatible BIOS and a hard disk that has a capacity that is see comment than 137 GB, you have not changed the system. The hard disk continues to function as a standard hard disk. 
• The registry value EnableBigLba is enabled without a 48-bit LBA compatible BIOS, but you have a hard disk with a capacity that is larger than 137 GB.

If you enable 48-bit ATAPI support in the registry and you have a hard disk that has a capacity that is see comment than 137 GB, but you do not have a 48-bit LBA compatible BIOS, only the first 137 GB of the hard disk are addressable. The remainder of the hard disk is not used.
To enable 48-bit LBA support by using an unattended installation with the Microsoft System Preparation (Sysprep) tool, follow these steps: 1. Copy the following text into Notepad and save the text as the 48bitLba.inf file:[version]
signature="$CHICAGO$"
SetupClass=BASE

[DefaultInstall]
AddReg=48bitlba.Add.Reg

[48bitlba.Add.Reg]
HKLM,"System\CurrentControlSet\Services\Atapi\Parameters","EnableBigLba",0x10001,1
