12/10/2023 0 Comments Uefitool dsdt modUEFITool is a cross-platform C++/Qt program for parsing, extracting and modifying UEFI firmware images. Found the module labeled with Setup and extracted the PE32 image section and converted to text using Universal IFR Extractor.Here’s a handy tool for interrogating firmware volumes: UEFITool! It is written by Nikolaj Schlej, and is great for examing the Regions/Volumes/Sections/Files that make up a UEFI image. then I opened the BIOS file using "UEFITool_0.22.4_win". in cmd using the command "filename /writeromfile." I was able to extract from the bios.exe file So this is what I did, I downloaded my Bios from the dell website, ).Īny ways after searching a lot on the internet I extracted my BIOS, I shall attach the files here hopefully someone can tell my dvmt prealloc from that. ( my edu.background is medicine so most of the in-depth tech stuff is very hard for me to understand. since we both have the same laptop with same specs i would be so grateful if u could provide step wise instruction on how to accomplish the above step.Ĭlick to expand.on the contrary RehabMan I went through the FAQ s and at that time I didn't know any other way to check dvmt pre alloc, at present after scouring the internet I still haven't figured out a way to accurately determine my dvmt pre alloc using windows machine. I read the link provided in step 4 about acpi patching etc. Thank you so much for the quick reply maquedexiju !! If i am experiencing this because i have not disabled my NVidia gpu please kindly provide me step wise instruction how to do it. If the issue is due to the ist file plz provide me with the config file you used. To check if it was the ist problem i used the ist file in attachments that u have provided(inside the post-install folder) i simply replaced it with the config file in the efi partition of the usb, in this case the progress bar in the apple logo screen comes half way and my laptop restarts. Here is the first problem i am experiencing now, as per the this link: ,i created my bootable usb (i made no changes to the ist file), but i am stuck with the apple logo (progress bar completes more than 70% then hangs) i am not able to reach the sierra install screen, Yes i understand it would be very difficult for you am grateful u created a specific guide for dell 5577, so guess ill try to troubleshoot the problems as i encounter them. If u could create a specific stepwise guide from scratch on how u installed on your laptop would be immensenly appreciated and will be grateful. will following any of those methods cause dual boot issues or will it affect my gpu performance in any way in the windows environment. In step 4 u have asked to disable NVidia 1050 and the link provided informs about 3 methods which one did u follow. Maquedexiju it would be very helpful if you could create a detailed step wise guide (or video) on how to hackintosh (dual boot) dell inspilaptop without ssd, it will be very helpful especially for newbies like me out there. Hi maquedexiju, i would like to begin by saying how thankful i am that u created a guide specific for dell 5577( i have been searching the internet from quite some time now), thank you!!!Īlso i would like to inform that i am new to hackintosh and to this community so plz forgive me for lack of knowledge that i may show. Last but not the least, thanks again, for the gorgeous works by the masters. This is easy to solve if you don't hurry to login AppStore or use iMessage before handle the SMBIOS. The ALC256 is not supported by AppleADC, so used AppleALC to solve the problem, CodecCommand is needed also.Īpple will check your hardware information when providing you services, like iMessage. The monther board is series 100, so we need to change HDAS to HDEF in ist. You need to set the DVMT-prealloca to 64MB, I modified the BIOS, of course there are ways handling this problem.īCM94352Z is really easy to handle, and the instructions are here: If you use APFS as your file system, don't forget to add the apfs.efi to /EFI/Clover/drivers64UEFI. Keyboard, USB, built-in camera and Ethernet are working once I use the multiBeast to There are already many information in this forum, so I decide not to repeat them here.īecause this is a dual-GPU laptop, you need to do things described here: Fn not very clear (maybe caused by Karabiner?).Backlight control (I just didn't solve this problem).Audio Card: ALC256 (branded as ALC3234).Wireless and Bluetooth: BCM94352Z (I replaced the in-built one).Building a CustoMac Hackintosh: Buyer's Guide
