- TITLE :IBM Models 90 and 95 Require an XBIOS Partition to Boot
- PRODUCT :Windows NT
- PROD/VER:3.10
- OPER/SYS:WINDOWS
- KEYWORDS:
-
- ----------------------------------------------------------------------
- The information in this article applies to:
-
- - Microsoft Windows NT operating system, version 3.1
- - Microsoft Windows NT Advanced Server, version 3.1
- ----------------------------------------------------------------------
-
- SYMPTOMS
- ========
-
- After installing Windows NT on an IBM PS/2 Model 90 or 95, the system
- may no longer boot if the XBIOS partition is removed or converted to
- NTFS.
-
- CAUSE
- =====
-
- The IBM model 90 and 95 machines use the first section (usually about
- 3 megabytes) of hard drive space for their XBIOS partition. IBM uses a
- segment and offset system to keep this information from being
- overwritten. During installation of Windows NT, if you remove the
- XBIOS partition or all of the existing partitions and have Windows NT
- set up new partitions, the XBIOS information will be overwritten. Once
- Windows NT is installed and tries to reboot, the machine will hang
- because the XBIOS partition is unreadable.
-
- RESOLUTION
- ==========
-
- If the XBIOS partition is removed or converted to NTFS, it must be
- re-created. Use the Configuration disk that was shipped by IBM with
- the machine to reinstall the XBIOS partition onto the drive. Then
- reinstall Windows NT and do not delete or convert the existing XBIOS
- partition.
-
- For specific information on how to use the Configuration disk, contact
- IBM Technical Support.
