@reboot12 Hi, until now I cant set any nvram variable with any tool, that is on the market. Because all in Bios is still Write Protected. I can use those tools only for to check, if my change by hand of the nvram variable is correct. I look for the Byte pattern of each nvram variable with UEFI tool. For the search via UEFITool I use Byte length of about 300, because with shorter length I always get other "matches". I correct those 3 raw files by hand via Winhex. Raw files in CEF5B9A3-476D-497F-9FDC-E98143E0422C EE4E5898-3914-4259-9D6E-DC7BD79403CF 77D3DC50-D42B-4916-AC80-8F469035D150 For 0xCB3 I change Byte pattern from 01 ==> 00 by hand in each of those 3 raw files. For 0xCBE I change Byte pattern from 00 ==> 01 by hand in each of those 3 raw files. May be, that all nvram variables are stored only in this 3 raw files. But because I cant set off the Write Protection from Intel, this Write Protection sits on other place too, may be even not in Bios but on other chip on mainboard, crazy.. Then I integrate this 3 raw files, each modded at 2 places for 0xCB3 and 0xCBE, back into Bios via UEFITool. Then I flash this modded Bios with FPT.efi. After this I clear CMOS via its jumper. And voila, CSM is enabled, but nothing of this can be seen in Bios. Would be nice, to set all the other nvram variables too, that enables the CSM menu in Bios. Also the menu for to select the graphic card is still not there Dietmar

XP SP3 on Alderlake N100 cpu, 6 Watt Dietmar Now, this board is full XP SP3 compatible: Sound, Lan, Graphik, COM1, LPT1, PS/2 combi (works), Harddisks, USB3, USB2, nvme all works. And it is fast.

Yesssaaa I succeed to enable CSM mode, even it is not shown in Bios^^ Dietmar PS: Just now I am installing XP SP3 on the ASRock N100DC-ITX. EDIT: After flash of Bios Modd, you always have to clear CMOS with jumper! Here is the Bios for working CSM of the ASRock N100DC-ITX and all the needed EFI tools. No EEPromer is needed! Intel lost this time https://ufile.io/l3w3s78e EDIT2: I install with Firadisk . When you want to see F8, you have to disconnect this USB stick for a second and reconnect. The same is needed for GUI Setup, when you see the running bar, crazy^^..

Oh crazy, I still get Write Protected message during AmiSetupWriter 0xCB3 0x0 Hm, this looks, as if the UEFI nvram Write Protect BIT is not only located in Bios Dietmar EDIT: AmiSetupWriter 0xCB3 0x0 gives now answer: Current Setup[0xCB3] is 0x0 Ru.efi tells the same now for the very first time. That means, the variable has indeed changed from 01 ==> 00 via Bios modd. But still the crazy message after this: SetVariable call returned Write Protected. This means: I can change nvram Variables via Bios Modd, but I cant change this Write Protect until now.

@reboot12 Here is the original Bios 1.06 file and the modded 1.06 one without Write Protect for the UEFI NVRAM variables for ASRock N100DC-ITX board, Bios Version 1.06 Dietmar https://ufile.io/b28vzhl0 EDIT: Cool, I can flash this Bios without EEPromer. Instant flash tells: Secure fail, but FTP.efi for 128 Bios works from USB stick.

@reboot12 Next search with UEFI Tool. I found those Hex Values in 3(!) different raw files. In each of those raw files exact 1 times: Needs to be checked VERY careful, I search for a sequence of about 300 Bytes each. CEF5B9A3-476D-497F-9FDC-E98143E0422C EE4E5898-3914-4259-9D6E-DC7BD79403CF 77D3DC50-D42B-4916-AC80-8F469035D150 Dietmar

After crazy search in original Bios I found the place, where the UEFI variables are set to Write Protected Dietmar 010101010101010101000001000001556E02011E414646641E466464000000000000000000000000000000000002011E414646641E4664640000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000010000000000FF0000000000010100000000020202010000020000000000000104FF0000000000000000000000 EDIT: It can be found at 2(!) places in Bios. I replace both 01 ==> 00. Überprüfung auf Unterschiede 1. F:\n100Biosmodd\06modd.ROM: 16.777.216 Bytes 2. F:\n100Biosmodd\06.ROM: 16.777.216 Bytes Offsets: hexadez. 500D6B: 00 01 FAD8A3: 00 01 2 Abweichung(en) gefunden.

@reboot12 I found this. But how to find with this the exact place, where the Variable is stored for to make UEFI write protected? I think, it is some Offset in the NVRAM region, but where exact I have to use the EEpromwrite to change this variable from 01==>00 Dietmar 0x4AB15 Form: UEFI Variables Protection, FormId: 0x298F {01 86 8F 29 84 1F} 0x4AB1B One Of: Password protection of Runtime Variables, VarStoreInfo (VarOffset/VarName): 0xCB3, VarStore: 0x1, QuestionId: 0x52C, Size: 1, Min: 0x0, Max 0x1, Step: 0x0 {05 91 88 1F 89 1F 2C 05 01 00 B3 0C 10 10 00 01 00} 0x4AB2C One Of Option: Enable, Value (8 bit): 0x1 {09 07 86 1F 00 00 01} 0x4AB33 One Of Option: Disable, Value (8 bit): 0x0 {09 07 87 1F 00 00 00} 0x4AB3A Default: DefaultId: 0x0, Value (8 bit): 0x1 {5B 06 00 00 00 01} 0x4AB40 Default: DefaultId: 0x1, Value (8 bit): 0x1 {5B 06 01 00 00 01} 0x4AB46 End One Of {29 02}

@reboot12 Always the same message "Write Protected". The funny thing on the webside https://github.com/ab3lkaizen/SCEHUB#ASRock is, that they tell, to succeed to write to such a write protected variable. In the end, only EEpromer helps. I can do, but where exact are those AmiSetupWriter 0xCB3 0x0 and AmiSetupWriter 0xCBE 0x1 stored in Bios? At least, the configurations file for them is stored in Bios Dietmar The corresponding Hex values are this: Is therein the 01, which I have to change to 00? 01 86 8F 29 84 1F 05 91 88 1F 89 1F 2C 05 01 00 B3 0C 10 10 00 01 00 09 07 86 1F 00 00 01 09 07 87 1F 00 00 00 5B 06 00 00 00 01 5B 06 01 00 00 01 29 02

@reboot12 Is there a general Bit in Bios, that you have to change for to enable Read Write to NVRAM? Dietmar

Hi, Has somebody an idea, how to make the NVRAM (NVRAM sits on Bios chip???) write enabled Dietmar EDIT: Can this be down with the UEFI file for to enable CSM SceEfi64.efi /bt bla bla bla SceEfi64.efi is the UEFI variant of the AMISCE tool.

@reboot12 Can you tell me the sequenz in EFI commandline from before, so that I can test, if my modd happened and if the Lock is gone Dietmar

@reboot12 I changed the original value in this Bios 09 07 04 00 00 00 00 ==> 09 07 03 00 20 00 01 0x4BF11 Form: CSM Configuration, FormId: 0x29AB {01 86 AB 29 15 21} 0x4BF17 Subtitle: Statement.Prompt: Compatibility Support Module Configuration, Flags: 0x0 {02 87 17 21 00 00 00} 0x4BF1E End {29 02} 0x4BF20 Subtitle: Statement.Prompt: , Flags: 0x0 {02 87 02 00 00 00 00} 0x4BF27 End {29 02} 0x4BF29 Suppress If {0A 82} 0x4BF2B QuestionId: 0x11F0 equals value 0x1 {12 06 F0 11 01 00} 0x4BF31 One Of: CSM, VarStoreInfo (VarOffset/VarName): 0xCBE, VarStore: 0x1, QuestionId: 0x561, Size: 1, Min: 0x0, Max 0x1, Step: 0x0 {05 91 2A 21 2B 21 61 05 01 00 BE 0C 10 10 00 01 00} 0x4BF42 Default: DefaultId: 0x0, Value (8 bit): 0x0 {5B 06 00 00 00 00} 0x4BF48 One Of Option: Disabled, Value (8 bit): 0x0 {09 07 04 00 00 00 00} 0x4BF4F One Of Option: Enabled, Value (8 bit): 0x1 (default MFG) {09 07 03 00 20 00 01} 0x4BF56 End One Of {29 02} and flash with EEpromer. Compi starts, but still no CSM can be choosen in Bios Dietmar PS: This is the modded Bios. Via normal Bios flash I was told, that Secure Flash failed, so EEpromer. https://ufile.io/x09np3zv

@reboot12 Can you make a try to unlock my Bios Dietmar https://ufile.io/aljnb4wv

Hi, is there a way to use UEFITool, for to unlock this AMI Bios? Or can the Bios direct been edited (Amitse, CFG Lock ?) with Ida Pro for to enable CSM Dietmar

@reboot12 How to log in into this chat Dietmar EDIT: Ok, I am there, as diderius6 .

@reboot12 No. I found only this: Launch EFI Shell from Filesystem device Dietmar

@reboot12 I did this already. But there is also no possibility in this Bios, to disable the onboard (cpu) graphic. But I can see Bios on screen with my external Geforce GT 730 card Dietmar

@reboot12 Hi, you are much better than me with this tools. Can you make a try for me for this Bios, thanks a lot Dietmar https://ufile.io/aljnb4wv

Hi, on the ASROCK N100DC-ITX I cant enable CSM in Bios. Crazy, I saw webside with this Motherboard, where in Bios you can select CSM. But in version 1.06, which comes with my board, no CSM selectable in Bios even there is CSM core as you can see with UEFI tool Dietmar PS: I saw this board also with Bios 1.10. But I dont know, how to get this. On Asrock website there is only the 1.06 Bios listed. EDIT: Now I think, no CSM in Bios because of the integrated iGPU. But how to disable this?

@reboot12 I noticed this behavior also on XP SP3. Yepp, something in registry changed. Because of this, I always make a copy of the whole folder Windows\system32 Dietmar
