See the instructions at board/pc/readme.txt. The mentioned 'pendrive' includes 
USB storage devices. You might need to tweak the kernel config to boot from 
real disks. Quoting commit 4e4545246f466 log message:
    
    In principle these base defconfigs should work just fine for other
    storage media != pendrive like sata or ssd disk, however driver support
    isn't there quite yet, and pendrive is mostly supported by usb storage
    plus the usual usb host controller drivers.
