Information for users of Microsoft Windows NT 4.0-based computers

If you install software updates to a Windows NT 4.0-based computer that has a system partition that is larger than 7.8 gigabytes (GB), your computer may not restart correctly.

For more information about general issues that may occur when you install software updates that replace the Ntoskrnl.exe file on a Windows NT 4.0-based computer, click the following article numbers to view the articles in the Microsoft Knowledge Base:
224526  ( ) Windows NT 4.0 supports maximum of 7.8-GB system partition
317050  ( ) "Disk I/O Error: Status = 00000001" error message occurs when you start the computer
Note You may experience this issue even if you have successfully installed earlier Ntoskrnl.exe file updates on computers with system partitions that are larger than 7.8 GB. To make sure that the files are located below the 7.8-GB boundary, some customers have successfully used third-party disk diagnostic utilities after installing the update but before restarting the computer. Additionally, some customers who have computers that can start from either Microsoft Windows 2000 or Microsoft Windows XP have used a feature of these computers to work around this issue. This feature lets the computer use the NTLDR and NTDETECT files from the version of Windows that supports a larger system boot partition.
