Hello everybody, i'm just a noob to this awesome forum, please pardon my bad English, i'd like to do some experimental stuff (BIOS hack), so i just used this interesting tool "OA3 Injection Tools" for Insyde BIOS posted by EFAI1 in page 43 on this thread to insert my own MSDM key for Windows 8 into my Acer laptop's BIOS (as a non UEFI it comes with no ACPI MSDM table, but already SLIC'ed), after carefully following the instruction it successfully created one (listed in BIOS dump) but then i get some problem, the key which was generated by the tool can't be changed or erased anyway (give an error such as "SMI 41 h fail", what does the error mean? Write protected or?). When i open RW Everything, it can't read ACPI tables and SMBus anymore (Clock Generator Error), seems that the ACPI tables are corrupted, how to fix that (erase MSDM table/reset back to default)? the OS (Win7) still works normally as usual though. My laptop is Acer Aspire E1-471 with Insyde BIOS V1.29 (already SLIC'ed 2.1, Non UEFI BIOS) with Windows 7. I've already tried to reflash my BIOS with the latest untouched BIOS from Acer to get factory default status, then created Flash disk Crisis USB drive to reflash with my own backup bios (Fn+Esc), but it's still same no satisfying result so far, the key, MSDM table + error are still there. After ull reflashing when i tried to open RW everything again, it still can't read the ACPI table for some unknown reason yet. Tried searching everywhere but still can't get a working solution. Any help and advice would be gratefully appreciated thank u
Really there's no point in adding a key to your bios. There is a hardware hash in the table & when you activate it's compared to the hash on the MS servers. Since your not injecting an OEMM key & submitting to MS then it's pointless...
Yeah lol finally i realize that thanks for the reply mate but now i just wanna reset my BIOS back to factory default (without any detected error e.g. in RW Everything, the OS works normally though), and sad i can't do/reverse that by using the previous tool that wrote it, can i just delete the ACPI MSDM table/key by it (how, always give me some errors), or instead i must use some other sophisticated tools or effort (honestly i have a little knowledge about BIOS hacks or programming, so a "simple" way is preferred, but not with Acer technician hehe) hopefully it's still repairable and i can fix it myself
I have been looking for a tool to flash modded bios for Acer v5-573p. With the Insyde utility I get the error "It only supports to flash secure bios on current platform. The image to be updated is not a secure BIOS." Any help please. Thanks
@Badawa Modded bios on current Acer laptops can only be flashed via recovery mode or external programmer.
Thank you Tito for the tip. I decided to take the plunge, formatted a small capacity usb stick with fat and copied ZRQ.fd (the modified bios). Removed 20 screws and the base, disconnected the battery, used fn+esc to then power, the usb light flashed occasionally and a minute or two later laptop shut down. I thought success but testing shows it didn't flash. Mod was done by Coderush himself so I am sure it has to have the power management mod in it. I am not sure what I am doing wrong.
