    • The present invention allows NIC resources to be accessed through auxiliary power and an ASIC clock while the PC is powered down and while PCI power and the PCI clock are not available. The present invention also provides an alternate path for accessing the NIC registers, downloading keep-alive and alert-on-LAN packets to the transmit packet buffer (TPB), as well as uploading received packets from the receive packet buffer (RPB). The present invention also allows monitoring PCI activity and seamlessly servicing the PCI configuration cycle (when PCI power and the PCI clock are restored) in conjunction with responding to the access through the alternate path (while PCI power and the PCI clock are not available).
    • 本发明允许通过辅助电源和ASIC时钟来访问NIC资源,同时PC断电,而PCI电源和PCI时钟不可用。 本发明还提供了一种用于访问NIC寄存器,向POP发送缓冲器(TPB)下载保持活动和LAN报警信息的备用路径,以及从接收分组缓冲器(RPB)上传接收的分组。 本发明还允许监视PCI活动并且无缝地服务于PCI配置周期(当PCI电力和PCI时钟被恢复时),同时响应于通过备用路径的访问(当PCI电源和PCI时钟不可用时)。
