21. FLASHDISK MODULE
Athena is designed to accommodate an optional flashdisk module. This module contains 32MB to
128MB of solid state non-volatile memory that operates like an IDE drive without requiring any
additional driver software support.
Model Capacity
FD-32 32MB
FD-64 64MB
FD-96 96MB
FD-128 128MB
21.1 Installing the Flashdisk Module
The flashdisk module installs directly on the IDE connector J16 and is held down with a spacer
and two screws onto a mounting hole on the board.
The flashdisk module contains a jumper for master/slave configuration. For master, install the
jumper over pins 3&4, and for slave install the jumper over pins 1&2.
21.2 Configuration
To configure the CPU to work with the Flashdisk module, enter the BIOS (press F2 during
startup). Select the Main menu, and then select IDE Primary Master. Enter the following settings:
Type: User
Cylinders: 489 for 32MB flashdisk
Heads: 4 for 32MB flashdisk
Sectors: 32 for 32MB flashdisk
Multi Sector Transfer: Disable
LBA Mode Control: Enable
32 Bit I/O: Disable
Transfer Mode: Fast PIO 1
Ultra DMA Mode: Disable
Exit the BIOS and save your change. The system will now boot and recognize the FlashDisk
module as drive C:.
21.3 Using the Flashdisk with Another IDE Drive
Since the flashdisk occupies the board’s IDE connector, mounting it on the board prevents the
simultaneous use of another IDE drive with the same IDE port. To utilize both the flashdisk and
another drive, an adapter board, such as Diamond Systems’ ACC-IDEEXT, and cables are
required. The ACC-IDEEXT adapter board is described on page 72.
21.4 Power Supply
The 44-pin cable carries power from the CPU to the adapter board and will power the flashdisk
module and any drive using a 44-pin connector, such as a notebook hard drive.
A drive utilizing a 40-pin connector, such as a CD-ROM or full-size hard drive, requires an
external power source through an additional cable. The power may be provided from the CPU’s
power out connector (J12) or from one of the two 4-pin headers on the ACC-IDEEXT board.
Diamond Systems’ cable no. 698006 may be used with either power connector to bring power to
the drive.
