Differences between Serial/VGA/Nano i386/amd64

[Der_E]

Hi guys,

I am new in open firewalls like pfsense/opnsense and a little confused about the different versions of the 15.7 built.
So I understand Serial is for installation support with a console port. VGA is for hardware with a graphical interface like a VGA port. But what is the Nano one. I thought this is for small systems, but the image is the largest you can get. i386/amd64 ok this should be well known.

And last but not least... maybe you can give me a hint which one I choose best on a DELL Sonicwall TZ400 hardware.

Thanks

Nano sizes are large because they are images that match what it written on the memory card, in total.
The others are installers which copy only what is needed to the disk.

On the Sonicwall hardware I have no idea. Mainly depends on whether you can boot it like a normal computer.
More or less.
Does it even have a x86 processor? ARM/MIPS won't run OPNsense right now.

nano is short for NanoBSD, a type of FreeBSD image that was designed for embedded devices with flash memory (SD/CF cards these days).
