Abit BG7 (i845G) Mainboard
|
The company didn't stay aside from the World Football Championship and
released a board in a special "football" package. But there are no stuff
inside matching its new design (only some sets can contain an inflatable
ball, but it's very seldom).
Accessories:
- Package of a football design;
- Documentation: user manual in English;
- Cables: 1 ATA66/100/133 and FDD;
- Bracket with 2 USB ports, Rear, Center/Sub and SPDIF-In/Out of the TosLink
type;
- Bracket for the rear panel;
- CD containing:
- drivers;
- user manual in PDF;
- Hardware Doctor (system monitoring utility);
- Adobe Acrobat Reader;
- 3Deep;
- BuzzSoft software;
- Norton Antivirus 2002;
- DirectX 8.1.
The layout is not brilliant: FDD and audio-ins are not in very good
positions, and when a video card is installed it's difficult to handle
the IDE modules. It can be difficult as well to reach a jumper when the
board is already installed. Its function is shown on the textolite.
The 3-channel switching voltage regulator incorporates 6 capacitors
of 3300 uF and 3 of 1200 uF.
The following controllers are integrated:
- audio controller based on the ALC650 AC'97 codec supporting 5.1 audio systems
and having a connector for front audio inputs/outputs;
-
network controller based on the Realtek RTL8100B chip supporting 10BaseT/100BaseTX.
The board has reset and power buttons.
Non-unsoldered connectors: none.
The system monitoring is supported by the Winbond W83627HF-AW chip.
What is controlled:
-
voltage of processor, AGP bus, memory, +1.25, +3.3, +5 and +12 V, VBAT
and +5 V Standby;
-
speed of 3 fans;
-
temperatures of the processor (a built-in sensor), the board (a built-in
sensor) and an external sensor connected to the board.
There are 2 connectors for adjustable and 1 for unadjustable connection
of fans.
Brief characteristics of the board: memory slots - 3 DDR SDRAM;
expansion slots - AGP/ 5 PCI; I/O ports - 2 COM/ LPT/ 2 PS/2/ 6 USB 2.0;
dimensions - 305x225 mm.
Adjustment can be carried out with:

We used the latest available version of the BIOS - BIOS 8R.
The board is not bad, but it has nothing distinguishing as compared
with other i845G based boards.
