Specify boot order @var{drives} as a string of drive letters. Valid
drive letters depend on the target achitecture. The x86 PC uses: a, b
Interactive boot menus/prompts can be enabled via @option{menu=on} as far
as firmware/BIOS supports them. The default is non-interactive boot.
+A splash picture could be passed to bios, enabling user to show it as logo,
+when option splash=@var{sp_name} is given and menu=on, If firmware/BIOS
+supports them. Currently Seabios for X86 system support it.
+limitation: The splash file could be a jpeg file or a BMP file in 24 BPP
+format(true color). The resolution should be supported by the SVGA mode, so
+the recommended is 320x240, 640x480, 800x640.

@example
# try to boot from network first, then from hard disk

qemu -boot once=d
