The key to cheap OEM systems is integration. The more that can be crammed onto the motherboard itself, the less costly expansion cards are required.

The P4IBMS features on-board networking capability. Realtek’s RTL8100 hardware controller is used, and supports full-duplex 10/100Mbit networking. The Realtek controller is by no means an industrial strength solution, but is more that sufficient for home of office workstations.

The board also features on-board AC’97 audio, which has become an expected feature in recent years. Again, the AC’97 audio is not a professional solution, but is more than adequate for home use, or in office workstation fleets.

Still missing is integrated video. Chipsets featuring on-board video such as the 810 and 815 have helped to propel the Pentium III and Celeron into the mainstream market. As yet, Intel has made it clear that it wishes to keep the Pentium 4 in the mid to high-end segment, while the lower-end segment will be served by the Celeron. Until Intel wishes to push the Pentium 4 down into the space currently occupied by the Celeron (which likely won’t occur until the 130nm process is at full speed), don’t expect to see a Pentium 4 chipset with integrated video.
