WARNING
Handling Precautions
The MT1386 contains electronic components that are highly
sensitive to electrostatic discharge. Use extra cautron when
handling the MT1386 to ensure there is adequate grounding
around the work area the board is being installed. ALWAYS
wear a ground strap or ground your body by touching a
grounded object such as an unpainted metal device con-
nected to power ground.
In addition, the MT1386 has delicate crystal oscillators that can
break if subjected to sudden shock such as being tossed on a
table. Use care when moving the MT1386 from point to point.
If Troubles are Encountered
If, during the course of installation or operation of the MTl386,
the board displays improper operation, first consult this manual
as well as the BIOS manual. Then contact your dealer or
distributor for additional information. Should problems still
exist, you may contact Mylex Technical Support Department at
[phone]. Be sure to have the enclosed System Prob-
lem Report completely filled out.
