DFI NB76-EA (i845G) Mainboard

Unlike all other boards on this chipset this one comes with an ADD card. We have tested a preproduction sample.


  • Package: a standard design;
  • Documentation: a user manual in English;
  • Cables: 1 ATA66/100/133, and 1 FDD;
  • Bracket with COM and Game ports;
  • ADD card with DVI, Composite and S-Video TV-Out;
  • Reader for Smart and Secure Digital/Memory Stick cards;
  • CD with software including:
    • drivers;
    • system monitoring utility;
    • Boostek (changes FSB frequency from Windows);
    • Software for the smart-card reader;
    • DirectX 8.1.

The layout is generally good: only audio-ins are located between the PCI slots. It can be difficult to reach some jumpers when the board is already installed. Their functions are shown on the textolite.

The 3-channel switching voltage regulator incorporates 9 capacitors of 2200 uF and several less capacious ones.

The following controllers are integrated:

  • audio controller based on the Avance Logic ALC650 AC'97 codec with connectors for front audio-outs and SPDIF;
  • network controller based on the Realtek RTL8100BL chip supporting 10BaseT/ 100BaseTX.

Thanks to the Winbond W83L518D I/O controller the board supports (and has connectors for) readers of smart and SD/MS cards.

Non-unsoldered connectors: none.

The system monitoring is supported by the Winbond W83627HF-AW chip. What is controlled:

  • processor voltage (+1.5, +3.3, +5 and +/-12 V), VBAT and +5V Standby;
  • speed of 3 fans;
  • temperatures of the processor (a built-in sensor) and the board (a built-in sensor).

There are 2 connectors for adjustable connection of fans and 1 for non-adjustable connection.

Brief characteristics of the board: memory slots - 2 DDR SDRAM; expansion slots - AGP/ 6 PCI/ CNR; I/O ports - 2 COM/ LPT/ 2 PS/2/ 6 USB 2.0; dimensions - 305x245 mm.

Adjustment can be carried out with:

jumpers and switches Jumper to clear up the CMOS
Jumper to choose a FSB frequency 100/133 MHz
Jumper to start up computer with a PS/2 keyboard
Jumper to turn on computer with a USB keyboard
Jumper to choose Standby voltage on the PCI slots 3.3V or for expansion cards which do not comply with the PCI 2.2 standard
Jumper to choose a mode of the 6th USB port USB on CNR/ USB onboard
BIOS based on the 6.00PG version from Phoenix-Award Setup of memory timings + CAS Latency, Active to Precharge Delay, RAS to CAS Delay, RAS Precharge
Setup of memory frequency + Auto, DDR200, DDR266 DDR333 (DDR333 only at FSB=133 MHz set with the jumper)
Setup of AGP bus +
Setup of PCI bus -
Changeable scaler of AGP and PCI buses -
Manual assignment of interrupts +
Changeable FSB frequency + 100-200 MHz in 1 MHz steps
Changeable CPU multiplier + x8-x50
Changeable core voltage + 1.1-1.85V in 0.025V steps
Changeable memory voltage -
Changeable chipset voltage -
Changeable AGP bus voltage -

We used the latest available version of the BIOS of 17/05/2002.

The board will be primarily interesting for home users who do not play much, - it allows creating a real media combo device with a great number of functions, but it implies that a user will deal exactly with the ADD card supplied, not with a game video accelerator.
