I've been testing 5.3-BETA7 with an Intel SE7210TP1-E motherboard. It has Adaptec HostRAID and I'm using two Seagate 160GB SATA drives. So far things are working as expected. I had to create the RAID 1 array with atacontrol before installing FreeBSD. Below is the output of diskinfo -t /dev/ar0 with the default GENERIC kernel. I've done no tuning yet. /dev/ar0 512 # sectorsize 160041853440 # mediasize in bytes (149G) 312581745 # mediasize in sectors 19457 # Cylinders according to firmware. 255 # Heads according to firmware. 63 # Sectors according to firmware.
