The LS120

The LS-120
                                             

• Imations current LS-120 drive is known as the
  SuperDisk.

2
Characteristics

• The ls-120 supports very high density diskettes.
  It can have 2,490 tracks, as apposed to the 135
  tracks of the conventional 3.5 diskettes. Also
  the LS-120 has120 MB of storage capacity, but the
  3.5 only has 1.44 MB of storage capacity.
• The LS-120 is equivalent to about 83 floppy
  disks. (83disks x 1.44MB 119.52MB.) Unlike the
  zip drives, the SuperDisk is fully compatible, so
  floppy disks are still usable.
• The LS-120 uses an ATAPI IDE interface, so it can
  be installed alongside existing hard drives. It
  can replace the floppy drive.

Preparing to Install

• The LS drives minimum requirements are
  486DX2/66MHz processor, 8MB of RAM, and 5MB of
  free hard drive space. Some small systems do not
  have power connectors, in this case you may use a
  Y-splitter cable to add another connector. If you
  are replacing a Floppy just use the same power
  connectors.
• If you are planning to us the LS-120 as a
  bootable drive, youll need to check BIOS for
  compatibility. If BIOS does not support it then
  you must upgrade the BIOS before installing.

Basic Installation Process

• Prepare the System. Turn off power, remove
  screws.
• Set Jumpers. It will most likely be a slave
  device to an existing master device. Mount the
  LS-120 and connect power and signal cables.
• You will need to update the CMOS settings if you
  decide to use the LS-120 as a bootable drive.
  With the floppy removed and the LS-120 set as a
  bootable drive, it will become the new A drive.
  At this point save system CMOS and restart
  computer.

Some things to consider

• Some BIOS versions do not support the LS-120, the
  ones that do are..
• Award BIOS version 4.51PG or later
• AMI BIOS version 6.26.02 or later
• Phoenix BIOS version 6.0 or later
• Older versions of Windows support the drive as a
  removable and nonbootable disk.
• Many major system houses such as Packard Bell and
  Compaq do not support the LS-120 because they
  have their on OEM versions that must be
  installed.
