Never install PC board on the Top!
For best results, the cartridges should be formatted in the same
position as the final (predominatly) mounted orientation.

SYQUEST SQ2542 INSTALLATION MANUAL 104323-002 REV. C
READ BEFORE YOU BEGIN...
The SQ2542 is an ATA compatible drive.
Observe static-discharge precautions: Keep the drive in its static-
shielded bag until you are ready to complete the installation.
- Do not touch the PC Board or I/O connector pins.
- Always handle the drive by the edge or frame. Never apply pressure
to the PC Board or the top cover.
Use a grounded wrist strap at your workstation; if unavailble, ground
yourself frequently by touching the metal chassis of the system
before handling any components. Provide anti-static padding on all
work surfaces. Avoid static inducing carpeted areas.
Drive Configuration
-------------------
The user must select the drive features that are appropriate for
installation in their system. This is done by way of configuration
jumpers found on the drive PC Board.
CMOS Configuration (ATA Systems)
--------------------------------
Basic information about the drive must be entered in the host system
CMOS. The number of heads, cylinders and sectors per track are
specific to each drive and collectively define the drives "geometry".
CMOS configuration is system dependent and is usually accomplished
through a keystroke or combination of keystrokes during the POWER-ON
sequence or a utility such as setup after the system has booted.
Default Drive Geometry
----------------------
SyQuest ATA interface drives translate their physical drive
geometry's. If the drive types offered by the CMOS does not support
the numbers of cylinders, heads and sectors and your system does not
include a "user-defined" drive type, then select a drive type which
is less than or equal to the capacity given in the "Capacity"
section.
The drive capacity can be verified by using the CHKDSK utility,
provided with DOS after the high-level formatting has been completed.
If you do not know what drive types your CMOS supports, call the
Syquest Technical Support BBS, and download the FINDTYPE program
to assist in choosing an appropriate drive type.
