![]() If all else fails, reflash with your backup image. I do not have the funds to actually buy the laptop off Amazon, but if you do or have purchased the laptop off Amazon, try flashing the stock firmware image, and if that doesn’t work then pursue the alternative method. Then you would open the dumped binary data in UEFITool, and make the modifications using UEFITool against the full, dumped image. ![]() You would need to first back up your UEFI image by attaching a flash programmer to the SPI NOR chip and dumping its contents. Note that this is an inherently risky approach and you should back up your BIOS image before attempting to make this modification and flash. Then you would need to reflash the SPI NOR with a flash programmer. It also adds FreeBSD to the list of supported OSes thanks to pkubaj 's effort to make the tools buildable there. The difference is in the 5th byte ( 0x2 in the first line) to a value that is not 0x2 in the second line ( 0x1 in the second line).Īnd so on for questions 0x2 and 0x4 if modifying QuestionId 0x5 did not work, since it appears the QuestionIds are OR‘d. This release is full of minor improvements and fixes for minor issues that laid unresolved for several years due to them being so minor. I think it would likewise be possible to “undo” the graying out by changing the expected values in the firmware image for each of the three QuestionIds (0x2, 0x4, 0x5). It would be interesting to see though if updating the BIOS of a unit sold through Amazon with the BIOS image available from ACER and see if that enables those options. Can you see CPU multi now in your BIOS, you just can’t adjust it (It’s grayed out), or you can’t raise it above a certain amount What CPU do you have I checked your BIOS, this is not UEFI BIOS it’s legacy type BIOS, that is why you can’t open in in UEFITool. UEFIExtract can be used to extract UEFI image file into directory tree without using GUI. The question becomes is this configuration option set by default in the stock firmware available online? My guess is that it is not, but discovering this through reverse engineering is difficult. UEFIPatch can be used for automatic application of FFS file patches without using GUI. It does indeed appear as though there is a configuration option that grays out the Secure Boot settings. ![]() There are two UEFI firmware files embedded in the executable:Ġx123503 QuestionId: 0x5 equals value 0x2 P7zip Version 16.02 (locale=C.UTF-8,Utf16=on,HugeFiles=on,64 bits,8 CPUs Intel(R) Xeon(R) CPU E5-2660 v2 2.20GHz (306E4),ASM,AES-NI)īiosImageProc圆4.dll FH53M圆4.fd FlsHook.exe GH53M圆4.fd H2OFFT.cat H2OFFT64.sys mfc90u.dll msvcr90.dllĭing.wav FWUpdLcl.exe GH53M202.exe H2OFFT-W圆4.exe H2OFFT.inf bios.7z msvcp90.dll platform.ini MD5 Checksum: c113ee83aee992091d05d1a1efb88735Ġ 0x0 Microsoft executable, portable (PE)ġ79 0xB3 Copyright string: "Copyright (C) 2000 CW Sandmann 0x100 Copyright string: "Copyright (C) 1993-1995 DJ Delorie."ĥ90965 0x90475 7-zip archive data, version 0.2Ģ002445 0x1E8E0D MySQL MISAM index file Version 11 Target File: /home/nick/acer-predator-helios-300/GH53M202.exe
