The K4 can boot to diags, by using MfgTool from the Dev Corner "select boot" thread. From there, you can either export (share) the USB drive using that item in the main menu, or you can start an SSH shell from menu N-U-Z-X.
There is more information in the Dev Corner. Look in the K4 index wiki (and other indexes). Start with the Master Index sticky thread in the Dev Corner. Ask there. More people in the Dev Corner can help you with questions about diags and SSH and USBnetworking...
