The wiki has a lot of details about how to install firmware but I couldn't see instructions about how to check the currently running firmware version.
Furthermore, Raptor appear to be using "System Package" version numbers to represent some mix of individual packages that have their own distinct version numbers. For example, the Talos II v2.00 isn't OpenBMC 2.00. I feel this list would look better as a table showing the Raptor version in one column and other relevant versions in extra columns. For example, a column for OpenBMC, another for Linux kernel, etc.
Then if you log in and look at the uname output you can take the kernel version and try to deduce which System Package from Raptor you are running.
