What is this error ????What command did i miss ???

Have you got the SDL libraries installed & working?

What are you trying to do?

IF you want to boot from a cd this is the syntax
Put whatever is your cd drive in '/dev/cdrom'

If you want to install a different OS onto your harddrive this is the syntax
Put whatever is your cd drive in '/dev/cdrom'
Put whatever is your image location in 'myhdd.img'

NOTE: This requires you to have already created an img file(space for new OS).
This can be done
This creates a 2GB space(myhdd.img) on your harddrive, change it to whatever you find suitable.

Otherwise you can always do a '#man qemu'

Hope this helps
Cheers

The geexbox-1.0-rc2-en.i386.iso is a live cd , isn't ?That's why my -cdrom !

Do you have SDL installed. Respond to this or get no relevant help.

What is the packet for SDL in debian sarge ???What is SDL ?

Wouldn't you need to mount the .iso file first?

...?

Nope!! Its just an image file. You need to burn it to a CD first or try the above syntax bu Punk.

You don't need to mount it, qemu can treat an ISO image as an actual burnt disk.

Ok !I know for sure an iso livecd can be booted as if it was burnt on a cd with the -cdrom option by qemu.My question is SDL package for debian is libsdl-console right ?How do i use it ?
