We have a few of these Apple Xserve machines at work which weren’t doing much, so I thought I’d make better use of them. Naturally, this meant installing Linux on them.
These machines do not have a BIOS (or even any emulation), they use EFI and as such won’t boot the standard Linux install media. I knew that Fedora could boot EFI, so that’s where I started, with Leonidas (version 11). Unfortunately, the install media just wouldn’t work on this device, presumably as it has no BIOS emulation.
To cut a long story short, I had to learn how EFI works in order to get it booting and it wasn’t an easy thing to discover!
