supermicro x7dva-8 & freebsd/amd64 6.2-release failed

[Bill Xu]

Hi all,

I had a SuperMicro X7DVA-8 motherboard, the CPU is XEON 5110, hard disk 
is Seagate SCSI 146GB.

I could intall FreeBSD/amd64 6.2-RELEASE, after install, I reboot the 
system, it stops at "waiting 5 seconds for SCSI device... "

Anyone has idea about it?

Thanks.

Bill
