DHCP for PXE boot?

[zoob]

Hi,

Just wondering is there a way to configure DHCP tags 66 and 67 for PXE boot?

I tried to look for the config files for busybox and dnsmasq dhcpd's but I think I'm going in the wrong direction as I can't find the corresponding config files when I SSH into my router.

Thanks

EDIT: I saw Merlin's new firmware that gives us config file overrides... will give this whirl and report back.

EDIT2: Yup! I should have checked for the new Merlin firmware before doing anything. It was far easier than I expected:

1. Enable JFFS, format on next boot, reboot.
2. Edit /jffs/configs/dnsmasq.conf.add
3. One liner: dhcp-boot=pxelinux.0,,ip-of-the-server
4. Reboot router, start up tftpd on my server.

Done, now I can boot PING or whatever else I want with PXE. It works much better than using tftpd as my DHCP server which was quite slow and refused to lease out new IPs after the first one.
