Diamond Systems Low-Power PC/104 CPU Board With ZFx86 Processor Flashdisk Module, Configuration

Page 27

11. FLASHDISK MODULE

Prometheus-LC is designed to accommodate an optional flashdisk module. This module contains 32MB to 256MB of solid state non-volatile memory that operates like an IDE drive without requiring any additional driver software support.

Model Capacity

FD-32-XT 32MB

FD-64-XT 64MB

FD-128-XT 128MB

FD-256-XT 256MB

11.1 Installation

The flashdisk module installs directly on the IDE connector J8 and is held down with a spacer and two screws onto a mounting hole on the board. It fits within the height limit of the PC/104 specification, so another board may be installed on top of the Prometheus-LC CPU.

The flashdisk module contains a jumper for master/slave configuration. For master, install the jumper over pins 1&2, and for slave install the jumper over pins 2&3.

11.2 Configuration

To configure the CPU to work with the Flashdisk module, enter the BIOS (press F2 during startup). Select the Main menu, 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:.

11.3 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. 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 33.

11.4 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.
