I was in verse of installing RHEL 4 Update 3 on my HP Proliant server of 8 GB RAM and 143 GB Hard disk.When I booted with the first CD and it asked me about the installation and pressed "Enter".

It got stucked during the display :
Code:

I have already gone through that...Do I need to upgrade BIOS as it talks?
How to upgrade if yes?It talks about the Options to enable iommu but I dont see any those options on the BIOS as such.

I think You might have seen my queries on the same link too,...see the last post continued on the same thread.

You might want to try. As you have an HP Proliant server, maybe look on their site find your motherboard and it should have BIOS updates there.
