I'm assuming that the ULi doesn't have AHCI support as there's no option in=
the
BIOS for AHCI, only IDE and RAID.
=C2=A0
Will the MVS driver allow for any type of hot swap? It appears that when I =
pull
the drive out of any slot on the Supermicro card the kernel will panic and
system crash. Same thing with the on-board controller.
=C2=A0
Thanks,
Ryan

The boot drives are plugged directly into the Motherboard's SATA ports, which I believe is powered by a ULi M1689 chipset. I also have a Supermicro AOC-SAT2-MV8 PCI-X HBA card which has a Hercules-2 Rev. C0 SATA host controller built in. I've added ahci_load="YES" in my /boot/loader.conf and I can see that ahci.ko was loaded using klstat, but I do not see any drives ap pearing that use the ahci module. All drives are labeled /dev/ad* instead of /dev/ada* and hotswap doesn't work properly. Running dmesg |grep -i ahci comes back empty.<br />
