SYMPTOMS
When you are upgrading from Microsoft Windows 2000 Professional to Windows XP Professional, your computer may reboot during the &quot;Installing Devices&quot; section of Setup.



CAUSE
This issue can occur if your computer contains the NLynx PCI Twinax adapter (this is an AS/400 emulator adapter). When Windows loads the driver (Nltwinax.sys) for this adapter, the driver causes an error and the computer reboots.



WORKAROUND
To work around this issue:
 * 1) Boot your computer by using an MS-DOS or Windows boot floppy disk.
 * 2) Rename the Nltwinax.sys file in the %SystemRoot%\System32\Drivers folder.
 * 3) Reboot the computer and continue installing Windows XP.
 * 4) Click Cancel in any dialog box that prompts you for the location of the Nltwinax.sys driver.
