If you install Windows XP by using a Pre-Boot Execution Environment (PXE) network adapter or by using a remote boot floppy from a Remote Installation Services (RIS) server, the installation process may stop responding (hang) at the "Setup is Starting Windows" screen. A few seconds after this message appears, the screen may suddenly go black. You may also receive the following Stop error message on a blue screen:
STOP: 0x4000008a (0x822bcda8, 0x823978b0, 0x00000000, 0x00000000)
A kernel thread terminated to protect your system mutax.
NOTE: The four parameters that are inside the parentheses can vary according to the computer's configuration.

When you receive the stop error message, the RIS installation does not continue.


This problem may occur if the computer's BIOS does not notify Windows where the extra INT1A BIOS code is located. When Windows copies the BIOS code into the virtual DOS environment, Windows does not copy the extra INT1A codes. If the video BIOS of the display adapter calls INT1A, the video BIOS jumps to a location without valid code. This problem may occur if your computer uses an NVIDIA-based video card such as the GeForce2 or TNT RIVA.


To resolve this problem, obtain the latest service pack for Windows XP. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:

To work around this problem, temporarily replace the AGP video adapter with another supported PCI or AGP video adapter that uses a different chipset. You can then use RIS to install the client. After the installation is complete, put the original video adapter back in the computer, and let Windows detect the video adapter and install the video drivers.
