Just wanted to add a note for Linux Installation Server.
You should put the received HF or SSP package to the Installation Server depot in *.tar format. In any other case it will not show up in the list.
For example,
DP0907_B109_QCCR2A69192_HF1_UX.TAR.zip contains DP0907_b109_QCCR2A69192_HF1_ux.tar.gz which should be gunzipped to DP0907_b109_QCCR2A69192_HF1_ux.tar
