GEMINI Technical Manual Getting started with your GEMINI
Getting started with your GEMINI
Once you have a working GEMINI system, you can start adding other peripherals to enable you to start development. In this section we guide you through setting up and using peripherals and some of the features of the GEMINI.
The GEMINI uses a Phoenix-Award BIOS (Basic Input-Output System) to provide support for the board as standard. BIOS defaults have been selected to enable the board to operate with a minimum of devices connected. If you want to change these default settings, you use the Phoenix-Award BIOS setup program.
The setup parameters are stored in the CMOS RAM and are retained when the power is switched off, providing the battery backup supply is connected. If no battery is installed or the CMOS settings are corrupted then the BIOS will restore them from an onboard CMOS EEPROM.
What’s in the box?

Connecting a hard disk drive
The GEMINI provides an Integrated Serial ATA Host Controller, enabling up to two
SATA devices to be connected. There is also a single secondary IDE controller, enabling up to two IDE devices to be connected. Down to one only if the CF socket is in use.
When connecting SATA peripherals to the GEMINI, the BIOS automatically sets the following configuration:
Primary Master: Device connected to the onboard connector SATA1.
Primary Slave: Device connected to the onboard connector SATA2.
Secondary Master: Device connected the IDE port and set-up as a MASTER.
Secondary Slave: Device connected the IDE port and set-up as a SLAVE.
The BIOS automatically detects the hard disk drive(s) during the POST processes and configures the hardware correctly. The BIOS allows either a master or slave device to
be the boot device. See page 22 for further details.
Connecting a CD-ROM (IDE Type)
If a CD-ROM drive is required in the system, it may be connected in place of a secondary drive (as detailed above). The CD-ROM should be configured as a ‘master’ device.
Drivers are required to support a CD-ROM drive under DOS. If a bootable CD is inserted in the drive, the BIOS can be configured to automatically boot from this CD.

GEMINI Technical Manual Detailed hardware description
GEMINI chipset
The GEMINI chipset is based on the Intel 945GM graphics and memory controller hub and ICH7-M IO controller hub components.
Graphics and Memory Controller Hub
The 945GM Graphics and Memory Controller Hub (GMCH) contains four main components:
• An FSB interface to the Intel Core Duo/Core Solo processor.
• A system memory interface to DDR2 SDRAM.
• A hub interface to the IO controller hub (ICH4).
• An Integrated Graphics Device.
The GMCH supports the new generation of Intel processors with a front side bus (FSB)
frequency of 533/667MHz. See the Processor
section on the previous page for details of processor options.
Memory interface
The memory interface on the GEMINI board provides support for two non-ECC only
DDR2 (Double Data Rate) SDRAM 240-pin 1.8V unbuffered DIMMs (Dual Inline
Memory Module). Speeds up to PC5400 (533/667MHz) are supported with memory up to 3GB of capacity. The BIOS automatically reads the parameters of the inserted memory module via its SPD (Serial Presence Device) and configures the memory interface accordingly. No user interaction is required.
While applying two of the same modules, dual channel technology is enabled automatically for higher performance.
Onboard display interface
Based on Intel 945GM(E) chipset with built-in GMA (Graphic Media Accelerator) 950 graphics, the board provides high graphic performances with high bandwidth memory interface and dual independent pipe supporting multiple display modes. The board provides dual display function with clone mode and extended desktop mode for CRT,
LCD, DVI and TV monitor.
© 2007 Eurotech Ltd Issue B 44
GEMINI Technical Manual Detailed hardware description
Display interfaces
The GEMINI board supports a range of display interfaces. Details of these are provided in the following sections:
Analog RGB
A standard progressive scan analog CRT interface is provided from the GMCH. This is interfaced to a high density DB15 VGA connector mounted on the board. A 400MHz integrated RAMDAC provides support for resolutions up to 2048x1536 (QXGA) @
75Hz refresh rate. For connector details, see page 25 .
LVDS interface
The board provides one 40-pin LVDS interface for 18/24-bit single/dual channel panels to support FPD up to 1600 x 1200 (UXGA) of resolution. The GEMINI also supports a
5-pin LCD backlight inverter connector and one jumper for panel voltage setting.
DVI interface
The GEMINI board includes a Chrontel CH7307C DVI transmitter interfaced on the internal 945GM SDVO port. The GEMINI DVI interface supports single link DFP displays with resolution up to 1600x1200 (UXGA).
TV-out interface
A 480p/720p/1080i/1080p HDTV interface is provided from the GMCH. The GEMINI supports PAL and NTSC TV systems, and outputs YPrPb, S-Video and composite output interfaces thanks to three integrated 10-bit DAC’s.
Enhanced IDE and CompactFlash interface
The GEMINI provides:
• One Ultra DMA33 IDE interface to support up to 2 ATAPI devices.
• One CompactFlash Type II socket on the solder side with jumper-selectable slave/master mode on secondary IDE channel (see page
).
Serial ATA Interface
Based on Intel ICH7-M, the GEMINI provides two Serial ATA interfaces with up to
150MB/s of transfer rate .
© 2007 Eurotech Ltd Issue B 45
GEMINI Technical Manual Detailed hardware description
LAN interface
The GEMINI provides four Intel 82573L LAN interfaces which support the triple speed of 10/100/1000Base-T, with IEEE802.3 compliance and Wake-On-LAN capability.
Serial ports
The GEMINI provides four high speed 16C550 compatible UARTs, two via the
W83627THG SuperIO and a further two via the PCI based UART Fintek F81216D.
COM1 and COM2 are interfaced via the SuperIO. COM1 can only be used as standard
RS232 serial interface but COM2 is selectable between RS232, RS422, RS485 and
IrDA operation.
COM3 and COM4 are interfaced via the PCI UART F81216D and provide standard
RS232 serial interfaces.
Enabling the infrared port prevents operation of Serial Port COM2. The infrared port should be disconnected before using the COM2 port.
Super IO
An Winbond W83627THG Super IO controller provides legacy IO support. The
SuperIO resides on the LPC bus and provides:
• Two serial ports.
• Keyboard and mouse PS/2 interface.
• Parallel port.
• Floppy drive.
• IrDA.
• Hardware monitor.
• Watchdog.
• General purpose IOs.
Floppy port
The GEMINI provides a slim type floppy port, supporting up to two floppy drives.
© 2007 Eurotech Ltd Issue B 46
GEMINI Technical Manual Detailed hardware description
GPIO interface
The GEMINI includes a programmable 8-bit digital I/O interface. This provides general purpose I/O’s to the user’s application. The eight bidirectional lines are open collector and 5V compatible. GP0/1/6/7 have weak internal pull-ups.
Watchdog
The GEMINI supports a watchdog timer, integrated in the super IO chip with a software selectable timeout of 1ms to 255s. This can be used to generate a complete hardware system reset when an error causes a system lockup. By default, the watchdog timer is disabled and once enabled must be triggered within the timeout period programmed.
Onboard audio interface
The GEMINI provides the onboard AC97 5.1-channel audio interface with Realtek
ALC655.
USB 2.0 interface
Based on Intel ICH7-M, the GEMINI provides six USB2.0 ports. The USB2.0 interface supports transfer rates up to 480Mbps with an output Intensity of 500mA.
The USB2.0 protocol is only active when you connect a USB2.0 device. If you connect a USB1.1 device, the port automatically switches to the USB1.1 protocol. The maximum USB2.0 transfer rate of 480Mbps is dependent on device connected supporting this rate.
Power and fan connector
The GEMINI requires either an ATX power supply connected to the onboard ATX connector or a 8V to 24V DC input source connected to the onboard 4-pin ATX2.0 12V
connector. See ATX: Power supply connector
on page
.
The maximum power consumption of the GEMINI mother board is about 60W with an
Intel Core 2 Duo T2500 stressed to the absolute maximum power.
The GEMINI provides supports for one smart (4 wire) CPU fan allowing automatic thermal control of the board. This option is selectable in the BIOS and is disabled by default. The GEMINI also provides an onboard system FAN connector for 12V fan with tachometer input for speed feedback.
