Hi!
Just did a clean install of fvdw-sl-16 using 5.5 console and i had to switch slot 5 hd to slot 1 to make it work. Seems like 5.5 console is changing disks order and assuming slot 5 is sda. The first time i try to do this clean install, after all was done and booted, i was still using old firmware. Then i noticed that my install attempt was present on /dev/sde. I deleted all partitions on sda and sde just to make sure, did a new install and after reboot it didnt boot. So i moved disk on slot 5 (sde) to slot 1 and voilá.
