TITLE   :BUG: Floppy Drive Inaccessible on Computer with 512 MB of Memory
PRODUCT :Microsoft Windows NT
PROD/VER::4.0
OPER/SYS:
KEYWORDS:kbOSWinNT400bug kbDSupport kbGrpDSOPK

======================================================================
-------------------------------------------------------------------------------
The information in this article applies to:

 - Microsoft Windows NT Server version 4.0 
 - Microsoft Windows NT Workstation version 4.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

The floppy disk drive is inaccessible on computers with Intel 810e or 815
motherboards with 512 megabytes (MB) of memory installed, and on computers with
Intel 830 motherboards with 256 MB or more of memory installed, until Service
Pack 4 (SP4) or higher is installed. This problem limits how Microsoft Windows
NT 4.0 can be installed on these computers because the Windows NT 4.0 CD-ROM
does not contain Service Pack 4. The three-floppy-disk method of installation
does not work correctly. You will see a blue screen with an error message that
is similar to the following:

   STOP 0x0000007B (0xF2813BD4, 0xc0000034, 0x00000000, 0x00000000)
   INACCESSIBLE_BOOT_DEVICE

You can install by starting from the Windows NT 4.0 CD, but you cannot load
third-party drivers from the floppy disk drive until Windows NT 4.0 is installed
and Service Pack 4 (or higher) is installed.

CAUSE
=====

Windows NT 4.0 does not correctly allocate resources for floppy disk drives on
these computers (as described in the "Symptoms" section).


RESOLUTION
==========

To work around the problem:

1. Install Windows NT 4.0 from the CD-ROM.

2. Restart the computer and log on.

3. Install Service Pack 4 or higher from the CD and restart the computer.

4. Install a third-party driver from the floppy disk.

5. Reinstall the Service Pack if networking or some other operating system
   component was installed with the driver.

You can also work around this problem by installing Windows NT 4.0 from a network
install share that includes the third-party drivers. This method is described in
the Windows NT 4.0 Resource Kit.

STATUS
======

Microsoft has confirmed that this is a bug in the Microsoft products that are
listed at the beginning of this article.
