stub out the SAN req's in int13
Include-If: %if 0%{?patch-possibly-applied-elsewhere} We need to find some code or data to change so we can make the rom fit into the legacy size requirements. Comment out SAN support, and hopefully nobody will be impacted. Signed-off-by: Bruce Rogers <brogers@suse.com>
