RC is on air 🙂 13.5 (22G74)

se il driver e' un kext devi trattarlo come gli altri kext ed aggiungerlo in open core e dichiararlo nel config

A doubt I have post ssdt-xhc you are using

You said to try usb port to see if there was problems drone there i know usb map it is good because it works for different users on asus x670e hero 😉 as I said your problem is weird i would try to install with only gpu on first slot and also with only wd nvme disk on first gpu slot or to try an image of a fresh installed os if you have the chance to grab one

@fabio8vla struttura non cambia cambia il file all’interno di boot che la installazione di Windows sovrascrive devi rimettere quello di opencore se leggi sopra antuneddu ti dice i passaggi

se e' come dice all'inizio windows parte pero' per me installare dopo OSX windows fa perdere il boot di OSX e va ricreato il percorso non installo mai in questo modo ma preferisco dischi separati e quindi non sono certo 🙂

Se la situazione e' questa ed in questo caso partono bene entrambi i sistemi devi solo ricreare correttamente i percorsi di boot ( non va bene copiare la pennetta in questo caso) @netgearse passa o altri che sanno come fare (forse con bootice) possono darti una mano

Usb mapping is in ssdt-xhc and it seems you pass usb problem however try to follow this https://chriswayg.gitbook.io/opencore-visual-beginners-guide/alternatives/usb-mapping-on-windows

ciao @carmine-baforse dico una banalità, ma a batteria tampone hai verificato che sia operativa? dal primo sintomo sembrerebbe che perdi i parametri di configurazione del bios

this thread for bios settings.

It is enabled I have only a try to do detach all your hard drive s and use only WD 850 to instal or use a different media to create an usb installer no other ideas it is very weird you cant finish installation steps In my system I have zero problems and your system is pretty similar ah, windows or other system can be installed well?

@Coral for me all versions..but the try is for a (i hope) corrupted bios for any reason i use 1415 but also previous are good in my case i have to use bios version that supports high density dimm (i have 48Gb x 2) i would do in this way: flash 1415 using flashback button when done reset cmos (with back button a couple of times) load optimised settings (then csm off 4g on fast boot off) download again your OSX installer and then try macOS Installer icon could stay there for about 2/3 times (after initial reboot) if more it is not working EDIT i would use my EFI with only cores count patches modified for your cores number and without my SSDT for the GPU

Have you tried to flashback latest bios again? when weird things happen maybe there is a bios corruption somewhere

I would try to start with load optimized settings from bios and see

@Coral I splitted your problem in a new thread we can go on here to try to solve this weird problem 😉

I think it works in WS X299 Sage but I can't try by myself Bifurcation is for motherboard which does heavy shares of PCIE and CPU lanes (I am not so expert in this field), but x299 Sage has independent PCIex and it could work here are a bit off topic, but if you can buy from amazon and you think is useful for your system it is possible to try 🙂

@Extreme™Sorry I have explained in a bad way I think problem is not PCIE card, but the lanes of my motherboard (a combination of CPU kind and overall motherboard features) Your Sage motherboard should have enough lanes to have all 4 Nvme working because it is a more "pro" motherboard and it has a lot of independent PCIe 16x this is from my motherboard manual: you should check in yours if it has this section

@riky67se usi opencore la sezione e' PI (platform Information)

With your SAGE you should be safe to use it (check lanes on your manual) Instead my Hero is a more consumer motherboard and has some problem with bifurcation with PCIE slot In my particular case I have filled all four NVME PCIE card slots..but only two are working. I have sent back all to amazon because I would like to have four NVME on that PCIE card (plus other 4 I have on m2 motherboard slots)

@m.boncifacciamo un tentativo se vuoi scarica da area download HackCheck esegui la app e vai nella sezione disk e scegli il tuo disco M2 scegli il disco e poi clicchi su mount metti la password e cosi' ti compare la EFI del disco M2 metti dentro la cartella EFI le cartelle BOOT ed OC che hai su pennetta o su disco che usi per partire poi riavvia e vedi se ti trova un disco in piu' al bios per partire

Archive.zip overwrite your with this config.plist and copy the kext in kext folder this follows @Lorys89 advice i did also minor adjustment in Nvram section and platform info Backup yours things before overwriting them

qui già si era detto che ce ne erano diverse anche in altri dischi...

non ti arrendere che non e' cosi' complesso risolvere Noi da esterni abbiamo un po' di timore visto che hai diversi dischi su con almeno 4 partizioni EFi 🙂
