Subject: [coreboot] nvramcui: VGA console flashes if no serial console
Hi, all,
I am trying to use the nvramcui.
If the serial cable is plugged in, both the serial console and VGA console are
stable.
but if the serial cable is unplugged, the VGA console are flashing. The
flashing part is the text inside the frame "Press F1 when done", i.e., the CMOS
entries.
