S/T version - Rack Classic

[odzim]

Hi,

I'm trying to upgrade my old AV rack OS to 2.1 (currently it's 1.0) and cannot find out whether it's T or S hardware, basically nothing appears in the right corner of the display when booting up as the readme says. Any idea how to determine which version it is? Cheers

Just got this sorted using trial and error method - tried both files and the one for S worked. Thanks anyway
