EFI ?

[Frank Bonnet]

Hello

First of all : I am totally new in IA64 world ...
We have a machine that sleep into an office
which is a HP RX2600 server.

I have tested it with two CDROMs 5.2.1 and 5.3 BETA4
the machine bootup with success.
Entering into the disk partition editor I notice that
some partitions are labeled "EFI".

Before erasing all previous data I would like to know
a little bit more with EFI.

Anyone could give some infos/links about this ?

Thanks in advance.
