Hi,
1.I'd like to put splash image when boot up, could someone tell how to do it?
If all you want to do is show the TC logo set your framebuffer to a reasonable size for your hardware.
For example, in VBox I use boot code vga=783, which sets a very small resolution (framebuffer).
This centers the logo, and I can make it big using "scale mode".
When you don't wish to read text, let it be small.
Things will be different for your box (or VM), of course. Play around and see what you like!
