Hello All,

Happy new year!

(I hope this is not a dup post but I didn't see my original at

I'm trying to be a brand new user to DragonFly as your graphics
support is better than FreeBSD.

I'm trying to install DragonFly on my Asus X555LA[1] with either the
dfly release or a snapshot but the bios won't recognize the img or iso
with two different USB thumb drives. By recognize there's no option
for the attached USB thumb drive in the BIOS.

>From FreeBSD, I've tried this:
dd if=dfly-x86_64-4.4.1_REL.img of=/dev/da bs=1m
dd if=dfly-x86_64-4.4.1_REL.img of=/dev/da0 bs=1m conv=noerror,sync
dd if=DragonFly-x86_64-LATEST-ISO.iso of=/dev/da0 bs=1m conv=noerror,sync

>From ubuntu like OS, I've tried this:
dd if=DragonFly-x86_64-LATEST-ISO.iso of=/dev/sdb bs=1M

Right now I have an OpenBSD snapshot installed so I don't think this
is an issue with the BIOS and some secure boot thing, which is
disabled. I have this openbsd snapshot installed:

Does anyone see anything wrong with the dd commands I'm using and/or
have any guesses as what I can do differently to get the USB drives
