[Guide] Broadwell HD5500 Setting DVMT in InsydeH20 BIOS Laptops

Status
Not open for further replies.
Hi, is there currently an updated guide on how to change DVMT-prealloc without the use of bios. The laptop I am planning to get has a 3000x2000 screen and uses coffee lake UHD620 graphics. People who have hackintoshed this thing are stuck with only 22mb of iGPU memory due to not enough DVMT-prelloc (or that is what they think it is) I believe it needs to be 128MB but the laptop sets it to 96MB. I read this post, but when you mentioned you have to boot in legacy mode, that was a no go for this laptop. Other then asking for a modded bios (which I am currently doing) is there another way, or perhaps a updated guide on how to do EFI shell on newer systems? Thanks
 
Hi all, I'm not trying to install OSX but this is the only place that has the kind of shell I need. anyway When I boot it gets to the GNU Grub prompt but then freezes, any ideas? My motherboard is an obscure OEM (aahd3-ab, NOT HB! its -AB!). yes it's an AIO i'm trying to increase the amount of allocated ram to the igpu on the APU.

I'm trying to patch the DVMT pre-alloc, but the Universal IFR Extractor.exe tool crashes when trying to write out the text file (so I can get the variable name for DVMT pre-alloc). Does anybody have the proper variable name for Acer AN515-53 v. 1.19 BIOS so I can patch the DVMT pre-alloc?
 
Hi, thank you for your Guide, but I have trouble in the beginning.
I had extract the bios.exe and get a lot of datas. 3 of them were .exes, but winter couldn't extract these. So I get no .fd data or something similar. I tried to load all the datas in phoenix, but it didn't work.
I don't know what I should do know?
I have a Lenovo Laptop Y50/Y70 and I uploaded my bios.
Maybe you could help me with this?
Thank you very much and sorry for my bad english,
July
