360    @end example
361    
362    @file{bzImage} is a Linux kernel image.
363    
364    General options:
365    @table @option
366    @item -initrd file
367    Use 'file' as initial ram disk.
368    
369    @item -hda file
370    @item -hdb file
371    Use 'file' as hard disk 0 or 1 image. The disk images are simply raw
372    images of the hard disk. You can create them with the command:
373    @example
374    dd if=/dev/zero of=myimage bs=1024 count=mysize
375    @end example
376    where @var{myimage} is the image filename and @var{mysize} is its size
377    in kilobytes.
378    
379    @item -m megs
380    Set virtual RAM size to @var{megs} megabytes.
381    
382    @item -n script      
383    Set network init script [default=/etc/vl-ifup]. This script is
384    launched to configure the host network interface (usually tun0)
385    corresponding to the virtual NE2000 card.

402    Print this help
403    @item C-a x    
404    Exit emulatior
405    @item C-a b
