Check release note before bmc upgrade

In some of our Mitac/Tyan old mb/system when trying to upgrade to latest bmc version it is very important to check the included release note as there are steps mandatory and required prior to upgrade/updating the bmc

In this article we will use 8056T70AE26HR-2T-HE-TU as example in the latest bmc page

 

bmc latest version is 4.06 after downloaded the file in the release note Notice: section it said “
Switching to the correct SKU ID first, and then flash the BMC firmware”

This step is very critical but unfortunately the notes do not provide steps on how to do it. Even though there is a sku id listed above

We do have a knowledge based published by FAE Andy Yang on Oct 20 2025 on how to do it

The article should work on all tyan/Mitac products the steps required a linux running system with ipmitool installed. To install ipmitool command on linux system follow the guide here note in most cases root/admin account required:
