Asking this on both [serverfault][1] and [superuser][2].

When attempting to network boot RHEL 5.4 on an old ia64 machine I get the following error :

![alt text][3]

So I've basically followed the tutorial here : [http://www-uxsup.csx.cam.ac.uk/pub/doc/suse/sles9/adminguide-sles9/ch04s03.html][4]

DHCPD,TFTPD etc are already setup and working with standard x86 PXE clients.

I've unpacked the boot.img file into /tftpboot/ia64/ and passed the path to the elilo.efi file via DHCP with the filename ""; option.

Changing this filename generates a PXE file not found error (see below). So I assume that PXE has found the file... ![alt text][5]

The only thing wrong I can find in the logs is :

Jan 6 19:49:31 dhcphost in.tftpd[31379]: tftp: client does not accept options

Any ideas? I'm sure I hit a problem like this a few years ago but I can't remember the fix :)

Thanks in advance!
