Problem trying to uploading/downloading without monitor
-
Hi, im trying to multicast to 8 computers, I did thousand of times, but it’s the first time that I try in machines without monitor, in fact the 8 computers only have power and network. The process starts ok, until the please wait screen comes up, then if i don’t have a monitor plugged in the computer appears next to the “please wait” message, the following: [794.750054] [drm:pch_irq_handler] ERROR PCH poison intterrupt [812.025308] [drm:pch_irq_handler] ERROR PCH poison intterrupt]
the computers are optiplex 390 and if y upload o restore a single computer with the monitor plugged all works fine
¿any ideas?
Thanks.
