Hello everyone.
I just got a donated server from a university. It's Intel Itanium CPU. Fairly old, but is supposed to work.

There's no OS installed on the harddrives, so I decided to try and put gentoo on it.

Unfortunately, it can't boot the regular way our desktops boot (EFI doesn't support MBR Boot).

I was using gentoo based system rescue cd to boot, and it has efi folder with bootx64.efi file, but when I tell the server to boot off that file it says "unsupported", although it says it's a 64 bit firmware.

I'm really not sure where to go next from here. How can I boot into a live gentoo cd, or live system rescue cd?

Itanium is IA64, so be sure you're using an IA64 (not an AMD64/x86-64) boot disc.

ok, I downloaded the IA-64 minimal iso, but i'm trying to boot of usb. I did "dd" to write cd/gentoo.efimg to a usb stick, ant it worked, server booted the gentoo kernel, but then during sysinit it couldn't find rootfs. I guess that it's looking for cd/image.squashfs but where should I put squashfs to?

I'm afraid I'm not familiar enough with the boot process of the disc image you're using to answer that question.

I burnt the *.iso to a cd, and It can boot, but it still can't find root file system. I ended up copyting image.squashfs to a jumpdrive, and stating that as a root file system, but it mounts it as read only, will start with a few errors, and not let me log in :\
