From 6b65030f565c56ec6f1f7d5529b788f0ae039800 Mon Sep 17 00:00:00 2001 From: Wayne Xia Date: Mon, 27 Jun 2011 13:53:02 +0800 Subject: [Qemu-devel] [PATCH v3] showing a splash picture when start Made an option to let qemu pass a picture to bios, let the bios show it as a logo. By default it is off, enable it as following -boot splash_time=N,splash_filename=P N have a max value of 0xffff, unit is ms. P is the a file name or a absolute path. Currently a trial version of sea-bios could be used to test it.
