problem installing linux ia-64 over NFS

Hi all,
i am installinf linux ia-64 on my itanium m/c over NFS. The insatallable
of linux ia64 are downloaded from the ftp site of redhat ia64 linux. When i started the installtion process , it booted nicely from LS-120 floopy,i t probed me for network config of host and nfs server, then it ask me for the path of directory where installables are kept. when i gave it, it prompted the error that 'the directory does not contain proper installation tree';

Does it need a perticular directory structure, if yes what it is.

I Directory i download from FTP site was /pub/redhat/ia64 of the ftp m/c.

i down loaded it on my m/c in some directory say "x", then i mounted that
so i have /mnt/x
which has three directories : -ia64

					   |---redhat
						|--- base
						|---instimages
						|--RPMS
					   |---images
					-iso
					-SRPMS

What path should i give while nfs installations.
Desperately waiting for reply
