UPDATE AFTER BEING REFERRED TO #FEDORA:

<Madsret> I got problems connecting my sata harddisk to my pc after upgrading the motherboard, hope someone can help me.  Details: http://pastebin.ca/41636
<daniel> Madsret: It's a LVM issue
<daniel> Perhaps you're missing the initrd. Did you change the kernel when transfering from working to non-working state?
<Madsret> im not experienced, lvm? i dont think i changed the kernel either
<Madsret> So could it be the initrd?
<ananke> uhmm, it's not lvm issue
<ananke> lvm problem is just an after math of being unable to see the drives/controller
<Madsret> Well it does show the linux bootup menu with all kernels displayed if i press enter..so the hd is properly connected
<ananke> doesn't matter
<ananke> lilo/grub will still load the kernel regardless
<ananke> the kernel/initrd itself doesn't have the drivers for your new mobosata controller
<ananke> sure. redo the initrd/kernel to include support for your new mobo sata controller
<Madsret> alright, how to do that?
<ananke> uhmm,
<ananke> you boot using the old mobo, then you consult #fedora
