In short, you need to have set up:
dhcp tftpd-hpaThen, grab a recent PXE tarball and untar it into /var/lib/tftpboot (or wherever you've pointed your tftp server)
tar -C /var/lib/tftpboot -xvzf netboot.tar.gzI normally then add a couple of parameters to the append line in the auto target in /var/lib/tftpboot/debian-installer/i386/pxelinux.cfg/default:
interface=auto netcfg/dhcp_timeout=60You're now ready to try a PXE boot. Give it a go, and read http://hands.com/d-i/ for hints on what to type at the boot prompt to kick things off.
N.B. if you have a machine that doesn't support PXE booting, you can grab a floppy that will let you kick things off.
