再发个1024*768的启动画面，菜单相关设置在下面的 gfxboot.cnf 中.相关文件保存在联想网盘：

gfxboot.cnf:

; Sections are read in the order given in base::layout, with section 'base'
; implicitly added at the end. If a config value is given more than once,
; the first entry wins.
;
; If a screen resolution can't be set, 640x480 is used as fallback (and
; section '640x480' added to the layout list).
;
; If the penguin screen is active, section 'penguin' is automatically added
; to the layout list.
;
; Setting livecd=1 implicitly adds section 'live' to the layout list.
;
; Color values: 24 bit RGB (e.g. 0xff0000 = red).
