ABIT IC7-G (i875P) Mainboard
It looks like that the company stepped back from the radical MAX series: the
lack of COM, LPT and PS/2 ports wasn't accepted by the market, and two lines is
too much for a narrow niche of high-performance systems. Now ABIT focuses on the
Serial ATA support:).

in 9 languages;
- Cables: 2 SerialATA, ATA66/100/133 and FDD - the last
two cables are covered with black cambric to improve ventilation inside the case;
ABIT Serillel2 adapter for connecting PATA equipment to Serial ATA;
supply splitter for the Serillel adapter;

for BIOS updates via the Internet and flashes in newer versions under Windows).
The layout is not standard, but this time it's easy to reach IDE connectors
located behind the PCI slots; besides, the memory slots do not have as much stuff
around as before, and nothing prevents installation of full-size PCI cards. The
only downside is that the audio connectors are placed in front of the PCI slots.
It can be difficult to access the jumpers that let the system start from USB and
PS/2 equipment, but the value is to be set only once, and the CMOS clear switch
which is often used is easy to reach. Functions of most jumpers are not shown
on the textolite.
The 4-channel switching voltage regulator incorporates 8
capacitors of 2200 uF and several less capacious ones. There are also voltage
regulators of the AGP bus (2 capacitors of 1000 uF) and of the memory (4 of 1000
- audio controller based on the chipset
and Avance Logic ALC650 AC'97 codec; 5.1 audio system supported, front audio-outs
and SPDIF connectors provided;
- network controller based on the Intel
82547EI (Kenai II CSA) chip, 10BaseT/100BaseTX/1000BaseT (Gigabit Ethernet) supported;
SATA RAID controller on the Silicon Image Sil3112ACT144 chip supporting RAID 0
and 1 on the SATA150 protocol;
- FireWire bus controller based on the Texas
Instruments TSB43AB23 chip with the support of 3 ports.
+5 V supplied
in the StandBy mode is indicated with the green LED. The red LED goes on at the
Non-unsoldered connectors: none.
System monitoring is supported
by Winbond W83627HF-AW chip. It controls:
- processor, AGP bus,
memory voltages, +3.3, +5 and +12 V, VBAT and +5 V Standby;
of 3 fans;
- temperatures of the processor (built-in sensor) and
the board (2 built-in sensors).
There are 2 connectors for adjustable
and 3 for unadjustable connection of fans (one of them is connected to a fan on
the MCH's heatsink).

The board has everything for functional expansion and for good
electrical support of the system in normal and overclocked conditions. Besides,
it provides the best support for migration to the Serial ATA.
