It can't mount the installation media when using DVD and through USB the only issue I have is that the HDD does not exist when partitioning just the USB but other than that it works fine. I've got OpenBSD working fine on an ancient desktop dated somewhere between the 80's and 90's and I've ordered a usb to ethernet port since there is only the modem/dialup port. On the actual desktop I want FreeBSD running, yeah no progress yet.
