(As a short list: Sun X[24][16]00 servers, Intel SR25XX > with SAS, Some IBM xSeries, etc...). There is a workaround for Intel SR25XX with SAS backplane. It can be configured in BIOS to use the Intel Embedded Server RAID II technology. FreeBSD doesn't support it and still detects physical disks attached to mpt(4), but with this option turned on FreeBSD could be successfully booted. Probably turning it on installs the different int13 handler. I turned it on and configured JBOD. It has certain drawbacks, however. You should be careful and never use the last sector on the hard drive as it's used for metadata by the Intel Emdedded RAID. You can't use gmirror on the physical disks, for example. -- Spartak Radchenko SVR1-RIPE
