Try setting "Plug and Pray OS" to "No".

IMHO the Asus was a sub optimal choice for a server board.  I like some
of their boards for workstation use but for AMD servers, w/the exception
of 1 machine, have had pretty good results w/Tyan barbone units in the
Transport line.  Super Micro would also make my short list.  The Sun
x2100 that's been discussed recently may be an attractive candidate
pending on how well other's experiences w/it prove out. The mobo may
still be new enough to RMA in wh/case I'd go w/a non nVidia based Tyan
server board.  Yes, I know the nVidia stuff is supported much better
under 6.0 than 5.4 but it's still not as mature as the AMD chipsets so
I'm still staying away form them for a while yet for applications like
webservers where rock solid stability is a concern 

Olafo-- refresh my meory on this- what are the disk config requirements?
