============================================================================= AST RESEARCH, INC. TECHNICAL BULLETIN #0615 03-02-90 ============================================================================= CONFIGURING FLOPPY DRIVES FOR AST SYSTEMS To insure proper installation of a floppy drive into an AST computer system, make sure the following conditions are met. The AST diskette drive specification calls for "frame" ground to be connected to "logic" ground. On many floppy drives this is accomplished by the correct placement of a jumper on the drive's control electronics printed circuit board. Refer to the instructions included with the drive to verify correct placement of the grounding jumper. In addition, the grounding strap from the power supply should be attached to the drive's metal frame during installation. It should be noted that it may be necessary to move the ground strap from it's normal position on the Premium computer's chassis to a position where the ground connection on the floppy drive frame can be accessed.
