A little background:
I am planning to do some experimentation with diskless computers and net-boot.
The issue I found is that if I have four machines that boot from the same image, I need a way to identify that this machine is app-1, not app-4.
So after thinking where I could store this kind of information on a diskless machine I realized Windows is storing its CD-KEY in BIOS and OEMs are storing some custom data there too.
So my goal would be to store a simple string inside BIOS memory.
I know I can retrieve that on Linux using
dmidecode, but I have not found any
How can I store a custom string inside the BIOS, so that I could later retrieve it using dmidecode or some other tool?
Also, how are professionals handling storing machine-specific data in a diskless server environment?
