Samsung Expert X30 (BIOS P08RDD) & Intel HD 5500

2 posts in this topic

Recommended Posts

Num belo final de semana estive sem nada para fazer, então testei instalar o El Captain no meu notebook Samsung Expert X30.

 

A maioria dos meus problemas que tive foram facilmente resolvidos seguindo os tutoriais aqui do fórum (teclado, som, rede e etc).

Porém meu maior desafio foi ativar a aceleração gráfica da Intel HD 5500, mas com um certo esforço consegui.

 

Vou deixar aqui registrado meu legado:

 

Importante ressaltar que não me responsabilizo por danos que possam ocorrer no seu equipamento. Siga esses passos por sua conta e risco.

 

Esse procedimento funciona para qualquer notebook que utiliza a BIOS P08RDD.

Eu não sei ao certo se são todos da familia Expert, por isso é bom confirmar sua BIOS antes de continuar.

 

O EXE da BIOS que utilizei foi a ITEM_20160513_21598_WIN_P08RDD.exe

 

Em meus testes eu percebi que o Expert X30 possui 32MB de DVMT o que causa os KP ao forçar o ig-platform-id da Intel HD (0x16160000 ou 0x16160002).

O que resulta numa infelicidade de ficar sem aceleração de vídeo.  :(

 

Depois de uma tarde inteira, consegui descomprimir a seção Setup da BIOS do Expert X30. Segue as informações de DVMT:

 

DVMT (0x145)

- 32MB (0x1) <-- Padrão

- 64MB (0x2)

- 96MB (0x3) <-- Vamos alterar para essa opção

- 128MB (0x4)

 

Utilizando o EFI Shell eu consegui alterar a DVMT para 96MB e assim ativando a aceleração gráfica no El Captain:

setup_var 0x145 0x3

Sucesso!  :thumbsup_anim:

      Hi,

      I know those PMs drives have issues with MacOS/hackintosh as the booting drive. But anyone using them as storage devices only?

      I want to use them to store my data only, not booting the OS.

      Thanks!

      Hello guys!
       
      I'm using a Samsung ativ book 2 np270e5g-xd1br, with i5-3230m/HM75, and everything is working fine, except by sleeping and wifi connection (the Hackintosh internet speed is about 10% of the windows/Linux, and sometimes It downs randomly).
       
      I've tried a lot of tutorials but nothing solved my problem.
       
      Hope you guys could help me
       
      obs: I also figured that if I left the laptop for some minutes, It sometimes reboot.

      Hello everybody, it’s been a long long time since my last post here on this forum, I’m having a lot of issues trying to activate my graphic card, the system recognizes the graphic card but there’s not full acceleration, clearly shows up its name as Intel graphics HD 3000 with only 4 MB of video ram.
       
      I would like to know how I could fix this problem or a least any suggestion about it. The reason I came to this site one more time is because I have no clue how to edit or patch a DSDt.aml file, I have clover bootloader and still  (seems to be easy but not for me LOL) so I don’t want to ruin the system once again.
       
      My configuration is
      OS macOS High Sierra 10.13
      SAMSUNG series 3 NP300E5C-A0US
      INTEL CORE i3 - 2370M 2.4 GHz
      INTEL GRAPHICS HD 3000 
      WiFi ATHEROS AR5B95
      MEMORY 6 GB DDR3
       
       
      Wifi works *** Sound Works ***Ethernet Works*** 
       
      Battery indicators and trackpad gestures are not working yet.
       
      Thank you guys in advance, I’ll keep myself reading and searching for any kind of solution for my laptop..
