Title:  PROPER ARBITRATION LEVELS FOR THE IBM FIXED
        DISK ADAPTER


Some confusion has arisen concerning the hard disk arbitration level when
running theIBM PS/2 Reference Diskette Set Configuration option.  The
Advanced NetWare 286 Installation manual for the IBM Personal System/2 does
not clearly state that the arbitration level for the IBM Fixed Disk Adapter
MUST NOT BE CHANGED.

The proper arbitration levels are as follows:

    Controller     Arbitration Level          PS/2 Machine/Drive Size

        MFM                  3                    Model 50/20 MB
                                                  Model 60/44 MB
                                                  Model 80/44 MB

       ESDI                  5                    Model 60/70 MB
                                                  Model 80/70 MB

Although the Set Configuration option will allow the arbitration level to be
changed, the NetWare operating system will not come up if the levels are
not as stated above.
