Request : 32 bit VirtualBox

I greatly appreciate DietPi on my OrangePI SBC.
Unfortunately, I cannot use it on my old PC using VirtualBox, as the only available VM is 64bit.
Why don’t you release a 32-bit VirtualBox VM ?

To be clearer.
The VM in site seems to be a 64-bit one.
In fact, it doesn’t run on an old 32-bit PC (intel core duo). VirtualBox complaints about lack of processor’s virtualization features.
I suppose that an old PC requires a VM with a 32-bit version of the DietPi OS.
Could you please provide an appropriate DietPi VM, o suggest how to tackle this problem ?
