ex475 with Linux (fedora 20)

You need a video cable for this as it requires a bios tweak

CREATOR: gd-jpeg v1.0 (using IJG JPEG v62), default quality I got fed up with trying to figure out how to install WHS2011 onto my ex475. So I bit the bullet and just installed a linux distribution.

  1. Pull bottom drive from your ex475
  2. Put drive into spare USB container
  3. Create a VM using VM workstation and point it at a physical disk (Advanced settings for this)
  4. Install Fedora 20.
  5. Put drive back and boot it up

A couple of things I had to do. Disable Network Manager (NM) controlling the interface.

/etc/sysconfig/network-scripts/ifcfg-eth0

UUID="b65270ab-2b79-473d-8dce-942908383ff2"
NM_CONTROLLED="no"
BOOTPROTO="static"
DEVICE="eth0"
ONBOOT="yes"
IPADDR=192.168.1.20
GATEWAY=192.168.1.1
NETMASK=255.255.255.0

To resolve the slow disk startup issue required tweaking a BIOS setting. You'll need video cable http://www.mediasmartserver.net/forums/viewtopic.php?f=6&t=8066 just the bare minimum VGA only will do as keyboard/mouse on USB are fine.

  • Change from 4P(IDE)+4S(RAID) to 4P(IDE)+4S(IDE)

The video switches to a small font I prefer to see the BIOS font and all the startup messages - /etc/sysconfig/grub

GRUB_CMDLINE_LINUX="rd.md=0 rd.dm=0  KEYTABLE=us SYSFONT=True rd.lvm.lv=vg/lv_root rd.luks=0 rd.lvm.lv=vg/lv_swap LANG=en_US.UTF-8"
GRUB_TERMINAL="console"

4x 1Tb drives online.

Same old boring processor. I never bothered upgrading this.

File transfers are significantly faster than when it was running Windows - I can sustain ~83 MB/s on a 40Gb file.
