Using ADSL (PPPoE) in Netboot and install
 

Hi folks,
If I prepare PXE and ongoin to install
but I use ADSL(PPPoe) to connect to internet
so how can I get the base system to install?
(because netboot does not support PPPoE,altho installation via DVD/CD does)
like note below

can I put cd image into TFTP server?
Or the debian installer will support other way to mount/download some cd image or base system?
as I know,slackware give NFS mount
