# iPXE is configured by setting config macros in the source tree. The repo
|
|
# contains a number of config headers in ipxe/src/config/*.h which contain
|
|
# defaults. These defaults can be overridden by creating a corresponding header
|
|
# in ipxe/src/config/local.
|
|
# For example, the source repo contains ipxe/src/config/general.h, which
|
|
# explicitly does not define NET_PROTO_IPV6. To enable IPv6 support in iPXE we
|
|
# need to create ipxe/src/config/local/general.h and define NET_PROTO_IPV6 in
|
|
# that header.
|
|
# The following allows OVB to keep iPXE configuration under ipxe-config in this
|
|
# repo, and copies it into place in the iPXE repo during build.
