I think It will be perfect to add offset possibility too, so in this way It will be possible to use pattern (longer) and

#UEFITOOL INVALID BIOS IMAGE PATCH#

This issue and the program can do a wrong patch I have had to use longer pattern to individuate exclusively offset ! Search for these all and many times It happens that there are many of them and It try to patch all, so to avoid

#UEFITOOL INVALID BIOS IMAGE CODE#

Could someone point me in the right direction if this is not the case?Ĭlick to expand.I have got this problem when I tried It, the patch is based on code (or hex value) pattern and the program I figure if anyone can help with this it would be someone here. I posted this here because I've been using your tool to extract the modules from the uefi bios. ^_^ I think it's buried in the security core. If anyone could possibly help me find exactly where that value gets read, or possibly give me some pointers on how I might be able to locate that function, that would be great. If I remember right, it's the rightmost byte of the ebx register after executing the cpuid instruction with eax:0000000b, ecx:00000000, And once more with ecx:00000001. What I'm looking to do is trick the bios into reading the 'number of logical threads per block of execution resources' byte incorrectly. The bios performs a check to see what resources the chip has to offer, and sets up nearly everything around that. My preliminary testing seems to indicate that the non functional portions of the instruction pipeline are in fact there, and only need to be recognized by the bios to function again. I'm not sure how it happened, but it did, and I want to see if it can be replicated. Over on ocn, there was a guy who had the ht feature magically enabled on his i5 chip. I signed up specifically so that I could ask a few questions.

#UEFITOOL INVALID BIOS IMAGE UPDATE#

I really don't want to update it if I can help it as the machine runs fine as it is.Hey, I'm new around here. BTW perhaps I should have stated that my bios is V2.09 I note there is now a V2.19 but after reading on this site the number of people that have had black screens after following Acers update program telling them to update their bios and receiving a faulty bios which necessitated their machines having to be returned for bios repair. Acer must have an answer to this problem which I've seen is common to a lot of Acer laptops not just the S7 series. As I wrote previously the thumb drive works perfectly with my pc which has a Gigabyte UEFI bios, no need to revert to Legacy mode.

#UEFITOOL INVALID BIOS IMAGE INSTALL#

If Acer can install Win 8 with the bios set to UEFI I should be able to do the same and not have to resort to using Legacy Bios. I booted to F12 and no devices were displayed, just rebooting and letting the bios do it's own thing just gives the error message no bootable devices. rebooted to bios to double check none of the settings had changed, they hadn't. I moved it up to No 1 boot device, reset bios to UEFI, saved changes. I just remade my USB 3 thumb drive using Rufus set to NTFS and supporting legacy and UEFI bios, ISO of Win 8.1 My bios is set to legacy and recognised my Patriot thumb drive. when installing any OS I always disconnect all drives except the boot drive and do a custom install, removing any existing partitions inc the 300mb one so I always get a pristine install.

Has anyone on this site overcome this problem? The general consensus on the net is to just use legacy bios but I think this a cop out. Why oh why do you have to make us suffer so much, it is not necessary to do so, a laptop is a small pc using the same type components. I have had plenty of uefi pc’s and never had any problems like those encountered on Acer laptops. I really do not understand why Acer makes it so difficult for us to use our machines how we wish by locking everything down. Flip it back to legacy bios and you cannot use a previous disk image as it was made with the uefi in effect.

Impossible as the bios will not see bootable devices. Step 3 reset bios to uefi and attempt to use an original Windows disk image. Step 2 back into bios select legacy bios secure boot disabled and hey presto f12 will display bootable device and OS installation is successful. As well as Win 7 tool I also used Rufus with settings of ntfs and also fat-ex, uefi cannot see any of the drives. On the S7 I suffered the same problem as everyone else who tries to update their machines, uefi bios will not see any bootable device using f12 on boot. On my uefi bios pc it installed without problem. I wanted to install Win 10 so made a bootable usb stick using the Win7 usb tool.

#UEFITOOL INVALID BIOS IMAGE PASSWORD#

Notebook came with Win 8 installed through uefi bios, no password set. I’ve searched the web and found this a common problem but so far not found a cure.
