Used on an Asus Z8PE-D18 board with no EFI boot options. These instructions were written using Linux Mint to create the media, most distributions will work with little modification.
The PIKE 2008 is basically a LSI 9220-8i which you can flash with 9211-8i firmware. Flashing to IT mode allows you to have direct access to the disks to use btrfs or zfs or some kind of software RAID instead of the card's RAID.
There is a sticker on the back of your PIKE card which has 16 digits starting with 5000. Write this address down or take a picture of it. Note I put XXXXXXXXXXXX in this picture as these numbers are unique to the card. If your card does not have this sticker, instructions will be provided below.
