Specify boot order @var{drives} as a string of drive letters. Valid

| 312 | 315 |
drive letters depend on the target achitecture. The x86 PC uses: a, b |
| ... | ... | |
| 318 | 321 |
Interactive boot menus/prompts can be enabled via @option{menu=on} as far
|
| 319 | 322 |
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, |
|
| 325 |
when option splash=@var{sp_name} is given and menu=on, If firmware/BIOS
|
|
| 326 |
supports them. Currently Seabios for X86 system support it. |
|
| 327 |
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 |
|
| 329 |
the recommended is 320x240, 640x480, 800x640. |

# boot from CD-ROM first, switch back to default order after reboot |

qemu -boot once=d |
| 336 |
# boot with a splash picture for 5 seconds. |
