New LSI 9200 series controllers: 6Gb/s, 2.88 GB/s seq. reads, 1.87 GB/s seq. writes

hmmm that sounds really dangerous (don't want to loose my data)

but I've got some progress in meanwhile!!

I've been trying some more stuff and at some point I tried my RAID controller without any HDs attached... and guess what:
WEBBIOS STARTS!

After that I re-attached all HDs, reloaded my BIOS settings and tried again
WebBIOS still starts!

Finally I reinstalled the new LSI firmware again and also their "the trick" works

If any of you has an idea why the *$*$ WebBIOS won't start when my fully functional and healthy RAID5 is attached, then I'm all ears

btw: Since those SATA HDs are hot pluggable, could I just open WebBIOS and then attach the HDs?

edit:
really gotta go to bed now... 5 hours left to sleep
THANKS again for the support
