sceefi64.efi /o /s settings.txt   writes only about HII not possible.

Can I use ru.efi or dmpstore

@Dietmar

Maybe you have locked BIOS ?

Unlock BIOS in UEFI Shell: asw.efi 0xb52 0x0

I have unlocked:
 

Setup Question	= BIOS Lock
Token	=C42	// Do NOT change this line
Offset	=B52
Width	=01
BIOS Default =[01]Enabled 
Options	=*[00]Disabled	// Move "*" to the desired Option
         [01]Enabled

Because I cant SEE any name of variables and my Bios seems to be a little bit different from your,

a line like asw.efi 0xb52 0x0

may be very dangerous because it writes 0x0 at some unknown place, which may be not Bios Lock.

I disabled Bios Lock in Bios itself, but still gets message about HII not possible, means data are locked

@Dietmar

Maybe you need WriteOnceStatus unlock ?

If you have a WriteOnceStatus variable a different size than me, that's why it's better to use RU.EFI and change all values to 7F

@reboot12

Thanks, but I dont want to write something at unknown place in Bios.

I need a tool, for to SEE the variables from my Bios

Dietmar

[reboot12]

@Dietmar

Then use ru.efi

[Dietmar]

@reboot12

Yes, I have the same 7F everywhere

@Dietmar

For me HII database present and sceefi generate settings.txt OK

[Dietmar]

@reboot12

For me not: HII is blocked

@Dietmar

Maybe HII unlock after some edit DMI data - after buy motherboard I set some DMI data:

@reboot12

I can use ru.efi

and dmpstore in shell. dmpstore I cant save, but look at all the blocks.

Nothing more with sense just now

Dump your BIOS and send me to check offset for BIOS Lock - my is B52:

Offsets can be found offline in the bios file using ifrextractor.exe - for me offsets same from sceefi.efi and from ifrextractor e.g. Setup Item Hidden:

I get only a 16MB Bios flash, but the Hidden I found in Setup. Do you have an ifr extractor for XP? I think only version 0.5 or below will work
