Hi guys,
I’ve got Acer ES1-131-P5CX. Last known bios version is 1.24 avable here. After some investigation I dumped bios file using fpt -d -bios backup.rom from Intel TXE System Tools v2 r2. Attached as backup.zip. UEFITool 0.22.3 give me bunch of errors like these:
My first question is: Should I care about them?
It is InsydeH2) so I cannot use UBU Tool for all the hard work.
Ok. let’s go further. When I opened bios file in H2OEZE (100.00.02.10) I was able to export some oprom modules for example: vbios, gop_vbt and realtek.
Let’s take a look at vbios oprom module. I would like to update it but this particular one is very old - CherryView version 1005. So I wasn’t able to transer OROM VBIOS from the old version to the new one using excellent tutorial by @SoniX because I haven’t got corresponding bsf file (the oldest one from SoniX’s collection is 1008).
I don’t know how to update not only vbios but Realtek module and Intel GOP too. For example inside GOP driver (opened in HxD) I can see:
So - my next question is: How can I update these modules? (using UEFITool? H2oEZE?) And where can I find new ones? (GOP drivers in UBU Tool are for newer chipsets). What about OROM and EFI modules for SATA? I can’t see it.
Last but not least: What about Intel microcode? Inside this little laptop I’ve got Intel Pentium N3700 1,60GHz (codename Braswell 406C3). In @plutomaniac 's repository I found relatively new microcode dated 2017-12-25. But how and using which tools can I insert this mcode?
Can anybody cast same light on this problem?
