Boot image over http using only NETBOOT?

Boot image over http using only NETBOOT?
I need to achieve to boot ISO over http:\\ with NETBOOT from the BIOS. Without using any other boot device ie. USB,HD,CD.

So i cannot store the DHCP settings on any boot device.

Can this be done?

I have a standard wireless netgear router with DHCP but i understand not enough to pass to TFTP. I understand there is DD-WRT extended firmware for certain routers to be able to store PXE settings to pass to TFTP over the net but it doesn't support my router.

I was thinking if iPXE is in the Network ROM i can boot DHCP from there.

What are my possible options?

Regards.
Mark

RE: Boot image over http using only NETBOOT?
If you want to be able to boot machines without any local config you need to setup your network for PXE booting. That includes having both a DHCP server and a TFTP server on your network which you can configure as you need. There are some articles on http://networkboot.org/ that should help you out in getting it set up on either Windows or Linux. If you want to try to use your router for that you need to check its documentation if it is capable of supporting PXE booting.

If it doesn't support the setup for chainloading you can build an ipxe binary with an embedded script that breaks the infinite boot loop explained in http://ipxe.org/howto/chainloading.
