Jump to: navigation, search

Now that the Linux kernel is booting with its attached initrd, the following events take place:

  • try to find and load a valid network card driver: all the previous network communications happened through the UNDI network stack, which stands for Universal Network Device Interface and is basically a low-level, low-performance interface available for early network communication - it may not be used by modern OS
  • try to get a DHCP address from the CM server
  • set up the disk-less Linux distribution by using a mix of NFS mounts and RAM disks
  • start the distribution processes and services
