Add a file descriptor to an fd set. Valid options are:
|

|

@table @option
|

@item fd=@var{fd}
|
||||
This option defines the file descriptor of which a duplicate is added to fd set.
|

The file descriptor cannot be stdin, stdout, or stderr.
|
||||
@item set=@var{set}
|
||||
This option defines the ID of the fd set to add the file descriptor to.
|

@item opaque=@var{opaque}
|

This option defines a free-form string that can be used to describe @var{fd}.

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
|

(floppy 1 and 2), c (first hard disk), d (first CD-ROM), n-p (Etherboot
|

from network adapter 1-4), hard disk boot is the default. To apply a

particular boot order only on the first startup, specify it via

@option{once}.
|

|
||||
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.
|
||||
|
||||
A timeout could be passed to bios, guest will pause for @var{rb_timeout} ms
|
||||
when boot failed, then reboot. If @var{rb_timeout} is '-1', guest will not
|
||||
reboot, qemu passes '-1' to bios by default. Currently Seabios for X86

Use keyboard layout @var{language} (for example @code{fr} for
