[ipxe-devel] serial arrow keys broken

Tue Apr 22 23:25:42 UTC 2014

looks like the duplication is due to using the serial console define if I
remove it and rebuild it goes away

in kvm/sebios the bios output routine write to the serial console too hence
the duplication.

how do I build one ipxe.pxe that will work with kvm vm and serial on
hardware?
