I'm trying to get Mavericks to work on my Laptop Clevo p150em, but i have some problems. With the files above, I'm able to boot with just -x flag and with working internal display in 1080P(Don't know about the HDMI,DVI and DisplayPort, have not yet tested) But it seems like it missing drivers.

Hey there, just want to share my fail/success story and help people who might have the same laptop as I do.
I was getting really tired of not being able to update my driver to have something that works fine, and performances were at the limit of playability, so went on a crusade to find those precious fps. Also My keyboard must have an internal issue as it randomly type stuff, the keys sometimes were doing completely different letters etc etc.
First, Specs :
Clevo P150em, i7-3610QM, dGPU Amd 6970m (My 7970m Died last year, friend had a spare 6970m), 12Gb Ram, Crucial SSD M4 UEFI Windows 10 Windows 10 64bits on non uefi 7200rpm disk.
- PE4C with mPCIe since the p150em doesn't have express card.
- Sapphire RX 460 2gb (cheapest option, around 104 euros tax/shipping included).
*Random atx second hand 350Wpsu I got for 1500yens. ( Yes I live in Japan)
*Logitech G105keyboard (3800yens (35euros) )

My different fails
Tried to cold boot with everything plugged in, would get black screen.
Tried Hot plug after sleep. Got it recognized, installed drivers. Error 12.
Tried to override DSDT. Even when just extracting and compiling it got errors, never managed to get it to work.
Tried Setup 1.30 with many many different settings according to many many guides etc. Never got out of error 12 when it actually booted to windows. Then what happens to everyone not making proper backups when tinkering happened. It corrupted my boot partitions and never managed to recover it, first because of having a non UEFI bootable USB (Rufus can go to hell, unless there is a pb in official windows iso). Even Tried to do a Cmos reset, shouldn't have either...
Tried any bios setting possible (latest official bios, v17 I guess)
So I installed a new W10 64 on my second hard drive.
Installed drivers as usual.
How it worked :
*Bios set to primary display iGPU *Hot plugged, installed Drivers. *Unplugged, booted, uninstalled 6970m without deleting driver. *Booted, hotswapped. error 12. Uninstalled HD4000 without deleting drivers.
*'You need to reboot to apply'
*left the eGPU plugged. It booted, appeared on my TV and the journey was over.
Special note : Sometimes the internal display works, sometimes not, cannot figure out why, do not care anyway
I did benchmarks to check how slow compared to an actual x16 slot would the perf be nerfed.
Got 1608 Graphic score in timespy where usual rx460 4gb does 1780.
Not bad !
I'll put a few pictures when I am home, next step is getting the windows back on the SSD next week end!
I hope my experience can give a second youth to people's great P150em, I love it, it's a wonder.
