[syslinux] Help with PXE over ISO

[Scott Savarese]

Here is a bit of an odd request... II'm in a large company with lots of politics getting in the way of things. We were able to convince the main IT team to let us take over a subnet and run our own DHCP server. This lets us create a really nice PXE environment where we can build servers and ship them out. However, now we are in need to rebuild servers already deployed. We have machines in over 70 subnets around the company. Politics won't let me update the DHCP settings to point to my TFTP server.

So, is there a way to create an ISO image that will do the job of the initial DHCP request and can either send the TFTP request to my server, or simply run pxelinux for me pointing to the configuration on my TFTP server? I tried gPXE's rom-o-matic and got it to work for VM's but the second I ran it on HP machines it complained about memory issues (didn't like it when gPXE tried to overwrite the ethernet card's driver I think).

Any suggestions that I can try? I've heard about proxy dhcp but this won't work since many subnets only have 1 server on them.

Thanks,
Scott
