RH-7.3 xdelta patch error

["WM" <maverick_wayne@hotmail.com>]

Hi,

I was trying to update the RedHat 7.3 installer by following the readme (ftp://oss.sgi.com/projects/xfs/download/Release-1.1/installer/installer/i386/README-RH-VERSIONS).  I downloaded both of the files:

new-rh-7.3-patch.xdelta

RH7.3-SGI-XFS-1.1.iso

I followed the instruction on the readme, but I didn't have success.  Following are the output of my attempts:

# xdelta patch new-rh-7.3-patch.xdelta RH7.3-SGI-XFS-1.1.iso
[root@host] xdelta: wrong number of arguments

# xdelta patch new-rh-7.3-patch.xdelta  RH7.3-SGI-XFS-1.1.iso  RH7.3.2-SGI-XFS-1.1.iso
[root@host] xdelta: invalid patch

What am I doing wrong?  


Thanks
