You upgrade a computer that uses a processor other than an Intel processor to Microsoft Windows XP Service Pack 2 (SP2) or to Windows XP Service Pack 3 (SP3). Then, you restart the computer. After you do this, you may receive the following blue screen error message: When the printer parallel LPT1 port is enabled, you will receive the above error message

Notes

•	The results of a Stop error message may vary according to the computer's system failure settings.
•	The four parameters that are inside the parentheses of the technical information for the Stop error message can vary depending on the computer's configuration. However, for this particular instance, the first parameter will always be 0x000000A5.
•	You may see a Stop 0x000000A5 error messages caused by the problem that is described in this article, or it may be caused by the older BIOS installed on the motherboard.

Most computers include an image that the manufacturer created by using the System Preparation (Sysprep) tool. Sysprep lets the computer manufacturer generate an image that can be used on different computers. The problem that is described in the "Symptoms" section may occur if the original Windows XP Service Pack 1 (SP1) Sysprep image is created on an Intel-processor-based computer and if the Sysprep image is then deployed on a non-Intel-processor-based computer. Under this configuration, after the computer is upgraded to Windows XP SP2 or SP3, the Intel processor driver (Intelppm.sys) may try to load because an orphaned registry key remains from the original Sysprep image.

This issue may also occur if the original Windows XP SP2 or Windows XP SP3 Sysprep image is created on an Intel-processor-based computer and if it is then deployed onto a non-Intel-processor-based computer. Again, the Intel processor driver (Intelppm.sys) may try to load because an orphaned registry key remains from the original Sysprep image.

For more information about unsupported scenarios when you deploy a Sysprep image on a destination computer that has a different vendor's processor than what the original image is based on, click the following article number to view the article in the Microsoft Knowledge Base:
Note We do not support using Sysprep to install an operating system from an image if the image was created by using a computer that has a different processor. For example, you cannot create a Sysprep image on a computer that has an Intel processor and deploy the image to a computer that has an AMD processor.

Method 1

Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base: To work around this issue, follow these steps:

1.	Restart your computer in safe mode. For more information about safe mode in Windows XP, click the following article number to view the article in the Microsoft Knowledge Base: 315222 (http://support.microsoft.com/kb/315222/) A description of the Safe Mode Boot options in Windows XP
2.	Click Start, click Run, type regedit, and then click OK.
3.	Locate and then click the following registry key: HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\Intelppm
4.	In the right pane, right-click the Start entry, and then click Modify.
5.	In the Value data box, type 4, and then click OK.
6.	Quit Registry Editor.
7.	Restart your computer.

Method 2

To work around this issue, download the most recent BIOS for your specific motherboard from the manufacturer's Web site and follow these steps:

1.	Download the BIOS and rename the file before copying it to a floppy diskette. THE ASUS A8N32-SLI Motherboard cannot see a flash drive so you must flash the BIOS from the "A" drive with a disk that has been renamed to an eight characters plus an extension of <8 character file name>.ROM Note Depending on the manufacturer of your motherboard you need to activate the BIOS search by hitting F-2 in this case with the ASUS A8N32-SLI.
2.	When the BIOS is installed, the system will reboot automatically.
3.	If you did not touch the date settings for your system, the BIOS will leave the time setting as it was.
4.	Do NOT make any changes in the BIOS, especially if you want to use LPT1 for an older printer, as you will end up in blue screen again.
5.	If you must use the LPT1 port then when booting hit F-8 after the initial boot screen with the manufacturer's name on it. YOU MUST hit F-8 every half second or so and you must get the second Safe Mode Advanced Options Screen not the initial OS Safe Mode which is not able to let you choose the option: Boot to last good configuration after you activated the LPT1 port. It is preferable to purchase an LPT1 to USB cable, which is plug and play with no need to activate LPT1
6.	If you do not use LPT1 your machine will reboot normally after you have installed the most recent bios for your motherboard.
