hai all..
can any one plz explain me the complete procedure for pxe booting from
network.
For PXE boot you need to select the corresponding option ("boot from
LAN"?) from the PC BIOS.
1) There is a PXE BIOS on your NIC card that gets the control.
2) That BIOS contains a minimal DHCP Client and a TFTP client.
3) The DHCP clients asks for an IP address.
4) The DHCP serever on the network replies with an IP adress, PLUS a
TFTP server IP address PLUS a path name (of kernel image on TFTP
server).
5) The TFTP client contacts the TFTP server and downloads the boot image.
6) Generally this image is a boot loader such as pxelinux.
7) This boot loader then asks you which kernel you want to boot.
8) Corresponding to your selection, it downloads the appropriate kernel image
& optionally the initrd.
9) The kernel boots!
