I installed debian as instructed. Didn't see my sata drives in dmesg, so I figured my arcnumber must be wrong, from
http://forum.doozan.com/read.php?3,1893 it looked like
fw_setenv arcNumber 3089
Should fix it, so did that + reboot..Now goflex net blinks green for a while, then led turns off ;( If I unplug usb stick, then it blinks green, then starts blinking yellow.
Is there any way to get out of this without JTAG? Did I set the wrong arcNumber?
