Now it tastes all 6 formats on every provider in system. ataraid tasted only first level and subset of formats depending on controller vendor. While it is possible to do the same, I am not sure it should be done. But may be that all is not really a problem. Most users won't notice few extra requests unless something happen like disk failure, that can make boot to take much longer. 07.05.2012 16:24 =D0=CF=CC=D8=DA=CF=D7=C1=D4=C5=CC=D8 "John Baldwin" =CE=C1=D0=C9=D3=C1=CC: > > I installed 9.0 on a new desktop that used Intel's on-board RAID yesterday and > it worked great.
