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
======

version 3.1. This problem has been corrected in Windows NT Server version 3.5.
