What ever you do do not set 0x79 to 0x00 you will have to pull the battery

Good to know! What about changing 0x1234 to 0x0 ? Do you think that would do anything? Or that would be not a good idea? 0x1234 is a var_store..., but not a variable.

Nope never mind tried that didn't work..

Still trying a lot of different variables, however nothing remarkable to speak of as of yet. the 0x79 setting is probably the most significant change thus far.

Man I have tried soo many different settings, which appear to be working, however don't have any idea how to unlock the advanced menu, and I don't know how to make the bios accept an x64 operating system boot.. Need help

Ive tried everything so far going to take a try at it with a fresh mind today had to debrick my machine twice I noticed at the bottom of the hex page 0x218 & 0x79 seem to be mentioned together so Im going to try that in a bit and see what happens unfortunately Im not very familiar with allot of the abbreviation's mentioned in the hex page also it seems there is 2 var store's in this bios so im going to try to extract that today just installing dot net 3.5 to get phoenix tool working on the default 8.1 installation also just to mention I took my machine apart and it seam's everything is soldered to the board so 64bit OS would be beneficial for certain program's but not for ram upgrade (Y) but like I said before wish the peole on this site were willing to explain some of the detail's of the setting's but [censored] it im learning lot's just messing with this stuff up until 2 day's ago I had no clue their was an EFI SHELL let alone know how to compile one aha

Ah to unlock the menu's it's a little more complicated have to change suppress code from true to false! Ill figure that out

Awesome let me know how you did it. And same here I didn't know what EFI shell was either, so I'm just trying to learn whatever I can too!

Thanks again!

Is it like, this where the command would be setup_var 0x1800F 0x11FA to make the offset true.?

0x1800F Suppress If: {0A 82}
0x18011 True {46 02}

Or just setup_var 0xA82 0x4602 since it endian it would be 0x820A 0x0246 ? lol this is confusing stuff.

0x17F74 Option: UEFI, Value: 0x2 (default) {09 07 23 01 10 00 02}
0x17F7B Option: Legacy, Value: 0x1 {09 07 24 01 00 00 01}
0x17F82 End of Options {29 02}

I have, but it won't let me boot to anything with F12 and then I'm in the ACER Bios and it says No Operating System Found error and then it says please restart. Then when I restart everything in the bios is reset.

the ES1 probably has a different UEFI than the Sw5-012, although the Grub 32 should work on your system... In any case this whole 32 bit to 64 bit OS is confusing, and the only way I think we will be able to debug it is by unlocking the advanced features and messing with them. I have tried disabling all of the secure boot features, but I'm missing something.
