JFFS2 worked well enough when those laptops were built and tested!

os32 seems to dump core on XO-1.75 if the serial console is enabled either via

On a somewhat related note, I was building a firewall/serve box from an XO-1.5

display electronics.

They are truly XO-1 B2 series keyboards. My guess is that
someone was tasked with selling useless inventory...
They won't even work with XO-1 B3/B4 pre-production laptops.
