As for solderless, well practically all of them come with some form of solderless installation, but if your chip is covered in epoxy (black glue stuff) you won't be able to put a clip over it.
If that's the case then I think your only choice is between:
They attach to the DVD drive's ribbon cable, so no access to the chip is required.
If there's more I'm sure one of the mods will let you know
