P10 Motherboard BIOS Update - Hang On Reboot Issue

BIOS Update
It has been identified that systems running a BIOS version prior to 3104 may hang after a reboot. The BIOS must be
upgraded to version 3104 or later to prevent that.

Now that we are running into upgrade problems irrespective of the version/release because it is a bios issue,

ALL Support Engineers are requested to check the Motherboard and BIOS version before attempting an upgrade.

if the motherboard is P10 board and if the BIOS version is NOT 3104 dt.12/16/2016 or higher then exercise caution. The unit may hang while rebooting. So do not upgrade the unit if you do not have physical presence at the site to power cycle the unit in case it hangs.

The commands for identifying the same are given below. The only way out is to upgrade the BIOS version to 3104.
