Can't Choose Second Operating System on Olivetti M6 Computer

ID: Q110889

The information in this article applies to:
  • Microsoft Windows NT Advanced Server version 3.1

SYMPTOMS

You cannot successfully load the secondary operating system (MS-DOS) from Boot Loader on an Olivetti M6 series computer if you are booting from a SCSI hard disk drive connected to an Adaptec 154X controller. The following error message appears:

Non-system disk or disk error.


If you boot from the onboard IDE controller or any other hardware configuration, this problem does not occur.


CAUSE

This problem is caused by the specific interaction between the Olivetti M6 series computer and the Adaptec 154X controller.


WORKAROUND

You can use a bootable floppy disk to avoid using Boot Loader in one of the following two ways:

  1. Boot from a bootable MS-DOS disk when you want to use MS-DOS.


  2. Boot from a bootable MS-DOS disk. Use the SYS command to change the boot sector from the Windows NT Boot Loader to MS-DOS. When you want to return to Windows NT, boot with the Windows NT setup disk. Choose R for repair. After you insert the Emergency Repair disk, choose only to verify boot files on drive C.



STATUS

Microsoft has confirmed this to be a problem in Windows NT Advanced Server version 3.1. This problem has been corrected in Windows NT Server version 3.5.
