Okay, after considerable fiddling in the BIOS, I was able to narrow down 
a minimal number of tweaks that have to be done to get -BETA2 to boot 
with SCSI.  Go into the BIOS menu and:

o Disable the SLAVE MAC (NIC) from the Advanced->Integrated 
Devices->Slave Devices menu

o Disable IEEE 1394 from the Advanced->PCI Configuration->Integrated 
1394 menu

Doing that allowed me to boot, detect the drives and install the system. 
  Once that's done, the system seems to work pretty well, assuming you 
don't rely too heavily on the nve0 interface.

It sounds like your configuration is a bit different as you have SATA 
drives and I only have SCSI.  Don't know if these tips will help or not.

If anyone wants a dmesg on a boot -v from this (working) system, let me
