For now only png is supported and decoding is done in loader and not in kernel compared to splash screen support in sc(4). For using this add: boot_mute="YES" splash="/boot/images/freebsd-logo-rev.png" in loader.conf Differential Revision: https://reviews.freebsd.org/D45932 Reviewed by: imp, tsoome Sponsored by: Beckhoff Automation GmbH & Co.
