SUMMARY
This article describes the Microsoft Windows XP Service Pack 1 (SP1)
48-bit Logical Block Addressing (LBA) support for ATA Packet Interface
(ATAPI) disk drives that can increase the capacity of your hard disk
to greater than the current 137 gigabyte (GB) limit.
Note Windows XP does not support 48-bit LBA support unless you are
running Windows XP Service Pack 1 (SP1). If you want to enable 48-bit
LBA support, you must apply Windows XP SP1 or later. Windows XP Media
Center Edition and Windows XP Tablet PC Edition already include SP1.

XP, click the following article number to view the article in the

MORE INFORMATION
Windows XP SP1 includes 48-bit LBA support for ATAPI disk drives. With
this support, you can use hard disks that are larger than the current
137 GB limit. By default, support is enabled in SP1. To determine if
you are running SP1, right-click My Computer and then click
Properties. On the General tab, Service Pack 1 will be listed under
"System."
To determine if you have the latest ATAPI driver, verify that the
version of Atapi.sys in your %systemroot%\system32\drivers folder is
version 5.1.2600.1135 (or version 5.1.2600.1152 for Windows XP 64-Bit
Edition) or later. To do this, follow these steps:
Click Start, click Search, and then click All Files and Folders.
Type Atapi.sys, and then click Search.
If you do not find the Atapi.sys file in your
%systemroot%\system32\Drivers folder, click More advanced options in
Search Companion, click Search hidden files and folders, and then
repeat step 2. For additional information about how to search for
hidden and system folders, click the following article number to view
the article in the Microsoft Knowledge Base:
302347 How to search for hidden or system files in Windows XP
In your %systemroot%\System32\Drivers folder, Right-click Atapi.sys,
and then click Properties.
On the Version tab, note the file version.
If Atapi.sys is not version 5.1.2600.1135 (or version 5.1.2600.1152
for Windows XP 64-Bit Edition), obtain and install the hotfix that is
described in Microsoft Knowledge Base article 331958. For additional

331958 Hard disk may become corrupted when entering standby or
hibernation or when writing a memory dump
By default, the original release of Windows XP Home Edition and
Windows XP Professional do not have 48-bit LBA support enabled.
You must meet the following requirements to use 48-bit LBA ATAPI
support:
You must have a 48-bit LBA compatible BIOS.
You must have a hard disk that has a capacity that is greater than 137
GB.
You must have Windows XP SP1 installed.
For the original release of Windows XP Home Edition or Windows XP
Professional, 48-bit LBA can be enabled for testing purposes by
setting a registry value, named EnableBigLba, 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:
You use this registry value to enable 48-bit LBA support in the
original release of Windows XP Home Edition or Windows XP
Professional.
You install an earlier version of Windows, such as Windows 2000 or
earlier, 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 of Windows XP Home Edition or Windows XP Professional
by editing the previous registry setting and you did not meet the
minimum requirements, you may see the following behaviors:
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:
Copy the following text into Microsoft Windows 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
Create a file named Cmdlines.txt that includes the following lines:
[Commands]
"rundll32 setupapi,InstallHinfSection DefaultInstall 128
..\48BITLBA.INF"
Locate the Sysprep\I386 folder in the Sysprep image, and then create a
$OEM$ subfolder in this folder.
Copy the 48bitlba.inf and Cmdlines.txt files into the
Sysprep\I386\$OEM$ folder.
In your Sysprep.inf file, add a key named InstallFilesPath to the
[Unattended] section. This key must have the following value:
InstallFilesPath = "C:\sysprep\i386"
To add the previous settings to the Images folder, which had been
created with the Riprep.exe program, follow these steps:
On the remote installation server that contains the Riprep image,
create a Sysprep\I386\$OEM$ folder in the following folder:
RemoteInstall\Setup\Language\Images\Riprep_dir_name\I386\Mirror1\UserData
Note The word "Language" in the previous path reads "English" for the
English language, and "Riprep_dir_name" is the unique name that you
selected for the Riprep image.
Copy the 48bitlba.inf and Cmdlines.txt files into the $OEM$ folder.
Modify the Riprep.sif file in the
RemoteInstall\Setup\Language\Images\Riprep_dir_name\I386\Templates\Riprep.sif
folder (in addition to any other template files for this Riprep image
that you may have created), and then add the OemPreinstall and
InstallFilesPath values so that they are set up as:
[Unattended]
OemPreinstall = "Yes"
InstallFilesPath = "C:\sysprep\i386"
Close, and then save the file.
OEMs can turn on this support by using the Microsoft Windows OEM
Preinstallation Kit.
