# [PnPBIOS] read static resources on PnPBIOS init
#
# The PnPBIOS specifications recommend that we read static (boot time)
# resources when the PnPBIOS driver is first initialized. Because the
# PnPBIOS driver is not modular and can not be ran more than once per
# boot, it's safe to access the static resource data. Many buggy
# BIOSes actually expect us to read from it first. With this patch,
# the PnPBIOS driver will read static resources initially and then
# switch to dynamic mode when allocating resources for specific nodes.
