Abstract

Test the physical link between two machines one of which is not even provisioned with a OS. "Physical" usually means ethernet to me, but could mean WiFi, too.

Is the cable plugged in? ...to the right jack? Is the cable itself good? That is, are their internal breaks in any of the conductors from strain?

Make a Haiku "Live SD disk"

I worked at Be, Inc. for a year, so, yes, I have a soft spot for Haiku. I installed Haiku to an SD card like so...

dd bs=4M if=/media/d/haiku-r1beta4-x86_64-anyboot.iso of=/dev/sdd status=progress oflag=sync

Put...

iface enp13s0 inet static
	address 10.0.0.1/24

...and issue...

sudo ifup enp13s0

...on the (obviously, Linux) machine on the other end of the cable.

FWIW the Haiku ISO with MD5...

34fe53dfcaec218e719d88c0f5fccb17  /media/d/haiku-r1beta4-x86_64-anyboot.iso

...boots just fine on an HP ProDesk G1 DM as is evidenced by:

Unfortunately, both the devices App and listdev in the Terminal just list motherboard components, all of which are predicable Intel, but I promise: it's an HP ProDesk G1 DM.
