I would like to operate core 2 extreme qx 9300 with inspiron 1545
core 2 extreme The cpuid of qx 9300 is 1067 A
In the official inspiron 1545 bios the code of 1067 A is the one of 2008/04/09 old and supports core 2 extreme qx 9300 Precision M6400 bios is 2011/10/04 that is newer than inspiron 1545
So I thought that it would be better to replace microcode and did the following
[1], I have inspiron 1545 a14 bios (
https://goo.gl/U3Z5nj) and
Precision M6400 a13 bios (
https://goo.gl/k1UeTk)
Downloaded.
[2], both of the two exe files
filename.exe / writehdrfile
And I got two bios .hdr files
[3], I checked the position, size and date of microcode using MCE.exe in UBU_v1_70_b8_Dev and I was convinced that the bios file of inspiron1545 contains the old microcode
[4] Open the .hdr file using HxD Hex Editor and copy the character string of 0x2000 size from the position confirmed from the Precision M6400 bios file with MCE.exe and replace it with microcode of Inspiron 1545
[5], this worked Inspiron 1545's 1067 microcode .hdr file was replaced by the one on October 4, 2011
[6], I learned that PhoenixTool.exe can compress .hdr files into .gz and remodeled.hdr file was compressed by PhoenixTool but PhoenixTool had {no vaild checksums found}
![Huh]( "Huh")
![Angry]( "Angry")
[7] Then I compressed my unmodified. hdr file with PhoenixTool This worked fine The bios.gz file was completed
[8],When I confirmed the contents with 7-zip I confirmed the size that bios.hdr was in and it was exactly the same as the remodeled .hdr file so I overwrote it with a remodeled .hdr file
[9], usb
not remodeled biosfile.exe
I added a modified. Hdr file
bios.gz
I entered biosfile.exe / readgzfile in the dos window I thought this would work. But the dell bios updater said {ROM file CRC - 32 is incorrect. Bad ROM file}
![Angry]( "Angry")
![Angry]( "Angry")
![Angry]( "Angry")
I think that crc32 is checked before updating bios and it is supposed not to update unless it matches Is there a way to match crc32 with unmodified file or how to skip crc32 check?
You can use any method
I am tolerating risks
Help me
Thank you

I'm trying to activate the "Intel VT-x" option. My processor has support for this technology, but there is no such option in bios. 
Searching a lot here in the forum 
>https://www.bios-mods.com/forum/Thread-Unlocked-LG-A510-bios-thermal-control-menu-unlock< I found a bios compatible with my notebook, but in it was added only "temperature control".
, thx.
