This feature is NOT supported on all chipsets in coreboot! It also requires a USB2 controller which supports the EHCI Debug Port capability. See http://www.coreboot.org/EHCI_Debug_Port for an up-to-date list of supported controllers. If unsure, say N. # Note: This option doesn't make sense on Intel ICH / AMD SB600 southbridges # as those hardcode the physical USB port to be used as Debug Port to 1. # It cannot be changed by coreboot. config USBDEBUG_DEFAULT_PORT int "Default USB port to use as Debug Port" default 1 depends on USBDEBUG && !SOUTHBRIDGE_INTEL_I82801GX && !SOUTHBRIDGE_AMD_SB600 help This option selects which physical USB port coreboot will try to use as EHCI Debug Port first (valid values are: 1-15). If coreboot doesn't detect an EHCI Debug Port dongle on this port, it will try all the other ports one after the other. This will take a few seconds of time though, and thus slow down the booting process. Hence, if you select the correct port here, you can speed up your boot time. Which USB port number (1-15) refers to which actual port on your mainboard (potentially also USB pin headers on your mainboard) is highly board-specific, and you'll likely have to find out by trial-and-error. # TODO: Deps? # TODO: Improve description. config ONBOARD_VGA_IS_PRIMARY bool "Use onboard VGA as primary video device" default n help If not selected, the last adapter found will be used. config CONSOLE_NE2K bool "Network console over NE2000 compatible Ethernet adapter" default n help Send coreboot debug output to a Ethernet console, it works same way as Linux netconsole, packets are received to UDP port 6666 on IP/MAC specified with options bellow.
