集成网卡阿，现在的都是集成的，很少用独立的，没必要阿，所谓的集成是指直接把网卡的控制芯片打到主板上，通过PCIE与北桥进行通信。
以前的老机器的独立显卡都是PCI界面的，接到南桥，速度有限阿。
这个芯片REALTEK的比较多一些，因为比较便宜。
SiS630E 是有集成网卡的功能，看下面的资料就是到了，可能是你的板子设计的时候没有用吧。BIOS core是芯片组厂商给的，默认的BIOS里是支持的，但是主板商没有用这个功能。

SiS630E overview
The single chipset, SiS630E, provides a high performance/low cost Desktop solution for the Intel Slot 1 and socket 370 series CPUs based system by integrating a high performance North Bridge, advanced hardware 2D/3D GUI engine and Super-South bridge. In addition, SiS630E provides system-on-chip solution that complies with Easy PC Initiative which supports Instantly Available/OnNow PC technology, USB, Legacy Removal and Slotless Design and FlexATX form factor.
By integrating the UltraAGP TM technology and advanced 64-bit graphic display interface which adopts Share System Memory Architecture that can flexibly utilize the system momory up to 64MB, SiS630E delivers AGP 4x performance and up to 1GB/s memory bandwidth. Furthermore, SiS630E provides powerful hardware decoding DVD accelerator to improve the DVD playback performance. The !?±Super-South Bridge!?L in SiS630E integrates all peripheral controllers/accelerators /interfaces. SiS630E provides a total communication solution including 10/100Mb Fast Ethernet for Office requirement.
SiS630E offers AC!|97 compliant interface that comprises digital audio engine with 3D-hardware accelerator, on-chip sample rate converter, and professional wavetable along with separate modem DMA controller. SiS630E also provides interface to Low Pin Count (LPC) operating at 33 MHz clock which is the same as PCI clock on the host, and dual USB host controller with five USB ports that deliver better connectivity and 2 x 12Mb bandwidth.
The built-in fast PCI IDE controller supports the ATA PIO/DMA, and the Ultra DMA33/66 function that supports the data transfer rate up to 66 MB/s. It provides the separate data path for two IDE channels that can eminently improve the performance under the multi-tasking environment.
