DHCP server on NT - "bootp" file on linux machine

[burgdavid]

Hello,

I'm a user (developper) on a network where I know there is a DHCP server under NT. For my work, I'd like to use bootp on an embedded board to test new linux kernels (I can also wrote them in flash but if it doesnt work the board may not boot anymore, ouch). The embedded board founds the DHCP server and get an IP, but don't get the kernel image adress to download (of course, not set on DHCP server).

I'd like it to download a kernel from my own linux PC where a tftp server is running (and working, I test succesfully the download of the kernel image through tftp with another computer).

The trouble is that I allready ask the network administrator who explain me that the DHCP reply settings are global (same for all computer) on the NT DHCP server and he doesn't want to set a image path and tftp server address in the reply or all PCs using DHCP will attempt to download a kernel image not done for them. He tell me it is not possible to set reply specifically for each network card physicall address (ethernet address is the namne, no ?).

Is there some easy and safe solution for this (I don't want to make trouble on the network of the whole enterprise) ?

Best regards,

David Burg.

My understanding is that PCs only attempt to pick up a boot image on bootup, ie if the bios has been set to use the lan as its first boot device. Therefore the Windows NT workstations should not download/use the boot image provided by tftp.

Not so sure. On my own workstation, network boot is disable on the bios (I just check) but I still see the "attempting to boot from network... failed" message at boot sequence.
