PXE boot

Procedure 74. Booting from PXE

Computer is powered up and boots into BIOS ROM
BIOS boots into PXE ROM
1. DHCP server responds with
  IP number
  TFTP server to contact
  (possibly) directory to fetch from
  and PXE executable to fetch there (i.c.pxelinux.0) ^[41]
PXE boots into PXE executable
PXE executable fetches configuration from TFTP server ^[42] ^[43]
PXE executable determines from the configuration file
- which kernel to fetch
- which boot parameters to set (if any)
- which RAMdisk to fetch (if any)
It fetches the kernel and the RAMdisk, and boots into them
The system has been booted.

^[41] Typically from /var/lib/tftpboot, which is often aliased to /tftpboot.

^[42] Typically from /tftpboot/pxelinux.cfg/.

^[43] The name of the file that is fetched is by default the IP number in hexadecimal. But this can be altered by the DHCP server.
