You can find some pictures of CF and DOM mods to unlock speeds faster than UDMA 2 in this thread--

It doesn't "force UDMA 6", but it does make your controller think that an 80 conductor cable is installed, which is a requirement to use > UDMA 2.
The controller that detects the 80-conductor cable via the "PDiag" pin (#32), is it located on the motherboard or inside the SSD/HDD itself?
The HDD/SSD. Are you trying to do it on a 44pin (2.5")? This is what you want:

If its one of those SATA to IDE type adapters, you need to remove the stuck piece of cloth over the solder joints on the back. Unfortunately this didn't work for my Gericom but you seem to have had luck. One thing I never tried was hooking it up to the 50pin IDE connector where the DVD drive plugged in which is what I think you're trying to do?
Not sure if there any adapters I could try for this but there should be I assume.
EDIT: Okay its called "Jae 50 pin" and there are adapters https://www.ebay.co.uk/itm/262283714242
Not sure but aren't slimline laptop CD/DVD IDE usually limited to UDMA2 regardless?

I have a SATA to Slim IDE 50 adapter based on the B76ZZ0041 chip.
On Linux (Lubuntu), it works in UDMA6 mode with the setting libata.force=80c.
On Windows 7? Unfortunately, only UDMA2.
The southbridge is VIA VT8235.
Note that on Linux it operates in UDMA6 mode through the Slim IDE connector (!!!), which isn't even designed to support anything above UDMA2 — the 32th pin isn't connected on the motherboard at all.
