Two elementary questions on LANs

[RAMAKISHOREBABU KOPPULA]

I have downloaded 64-bit DVD version of Fedora 15 and when was installing HP
Proliant DL580 G7 Server it is showing as Fedora 15 - Beta and it not
loading correct display driver for GNOME. Could somebody help me in
identifying suitable version of Fedora for  HP Proliant DL580 G7 Server?

Thank you.
