// first third of boot. Until the video driver is up, an ASCII rendition goes to
// the text console and the serial line; once fb_init() and bochs_vbe_init()
// have run, the real bitmap takes over as a graphical splash with a progress
// bar, and the remaining boot log continues on serial only.
//
// Both forms are generated from the same artwork by scripts/mklogo.py.
