SYMPTOMS
When you perform a system setup from a floppy disk on a Pentium Pro System with more than 1.792 Gigabytes (GB) of RAM, you may get the following blue screen error message:

STOP 0x0000007B (parameter, parameter, parameter, parameter)

Inaccessible_Boot_Device

Also, if you installed Windows NT 4.0 through other methods (compact disc, upgrade, and so on), the floppy disk does not work.



CAUSE
A new Pentium Pro Stepping (SB1) requires a modification to the Windows NT kernel.



RESOLUTION
The problem has been fixed in Service Pack 3 for Windows NT 4.0. If you have already installed Windows NT 4.0, apply the latest Service Pack. If you have to install from floppy disk, reduce the amount of memory below 1.792 GB until you applied the Service Pack.



STATUS
Microsoft has confirmed this to be a problem in Microsoft Windows NT Workstation version 4.0 and Microsoft Windows NT Server version 4.0. This problem was corrected in the latest Windows NT 4.0 U.S. Service Pack. For information on obtaining the Service Pack, query on the following word in the Microsoft Knowledge Base:
