You're right. But today that's the only way I found to install pfsense on Cf using a Jetway barebone, because nanobsd image written to Cf doesn't work fine for me: it doesn't complete the boot on that hardware or it doesn't configure right the serial port.
If in the future vga support will be included in the nanobsd image, I could get more info on the problem.
In addition I don't exclude It could also be a serial port configuration error I did.
Nanobsd's serial output only is a problem when thing doesn't work fine and debug informations are needed.
Thank you again for your support Jimp
