Uefitool macbooj efi firmaware1/25/2024 ![]() UEFI increases maximum hard drive size from 2.2 TB to 9.4 ZB (zettabytes). UEFI typically sports a friendly graphical user interface with animation as opposed to text-based keyboard only. UEFI (Unified Extensible Firmware Interface) is a specification for a more robust version of BIOS which addresses many of its old predecessor’s short comings. This newer PC has a UEFI BIOS which complicates things a little bit. However, that tutorial featured a traditional BIOS. You may want to check it out because it goes into more detail about the BIOS and shows a low-cost programming solution using a Pi. In my previous BIOS tutorial I repaired a Dell with a bricked BIOS using a Raspberry Pi and FlashRom. Their conclusion was a bad motherboard (out of warranty) and they estimated $500 to fix it (includes shipping) assuming that it was the actual problem.Ī little online research indicated that reboot loops are a common problem with the ASUS X99 motherboard and one possible cause is a corrupt BIOS firmware which could be remedied with a BIOS upgrade, which is more difficult to accomplish when the computer won’t boot. None of the aforementioned corrected the rebooting loop. We disconnected all the peripherals, spent a lot of time moving RAM sticks around, tested the power supply, disconnected the CPU and removed the graphics card. Is not getting past the POST (Power On Self-Test) so the CMOS is not accessible. After a few more seconds it powers back on by ![]() ![]() However, a few seconds later it shuts off. Upon power up, the computer lights up, fans The computer is stuck in a rebooting loop. Both the CPU and the graphics card are liquid This model has an Intel i7-6850K CPU running at 4 GHz with 32 GB of DDR4 RAM and a GTX 1080 graphics card. Reading HSFSTS register.The broken computer is made by Digital Storm which is a Silicon Valley company specializing in performance computers. ![]() Version: 8.Ĭopyright (c) 2007 - 2012, Intel Corporation. Please download FTK for Windows from the link in third post, then open Administrator console, cd to FTK/Win32 and execute fpt -i command. I know a way to overcome it, but it isn't simple. Intel is famous for difficulties on flashing modified BIOSes. It's a known issue with LZMA compression code compiled by Apple compilers, please try using version for Windows. Program version for OS X crashes with "Segmentation fault" message, what to do now? If you have non-AMI BIOS, I don't know any 100% working method except using external programmer, which are cheap and fast nowadays.Ĥ. If you have AMI UEFI BIOS (all modern desktop boards now have one, DO NOT TRY IT ON NOTEBOOKS), then you can use this method. If you have ASUS board with USB BIOS Flashback support, use it to flash your modified BIOS. I can't flash my patched BIOS due to "security verification failed", what can I do? No, but there are many people with patched BIOSes of all kinds, and very few negative reports.ģ. I have patched my BIOS, can you guarantee it will work after flashing? No, if the last message is "Output file generated", it's OK to have any other messages.Ģ. not found" messages in program output, is it bad? Please attach AIDA64's or DarwinDumper's report file to your "PMPatch didn't work for me" message.ġ. This program can produce corrupt BIOS images, try them on your own risk. Usage: pmpatch /path/to/original.bios /path/to/patched.bios The utility is BSD-licensed and available on GitHub.Ĭompiled versions for Windows and OS X are here. This patch works on boards based on 5th, 6th, 7th and 8th series of Intel chipsets, so NM10 and similar ones are supported - there is nothing to patch in that BIOSes. It's tested on AMI, Phoenix and Insyde UEFI BIOSes and it works. I wrote an utility to patch modern UEFI BIOSes from different vendors to prevent them from locking MSR 0圎2 and therefore make the system with patched BIOS compatible with native OS X power management.
