Native BIOS hasn't files 06F7.PAT & 06F7.HSH, but I see it on your screenshot.
Explain it.

I've replaced microcode twicely by hex editing a iso file at offset 146C0A and 18C2ED. I checked microcode list by intelmicrocodelist.exe. I can't even create a own iso, beacuse after that bios can't boot up this iso and GRUB4DOS says "Minimal BASH-like line editing supported." etc.

You see that files, because that was my atteption to create a own iso file and I just added these files to the native BIOS img file.

1. Use Rufus to make DOS USB stick.
2. Unpack 5CJT77A.img to DOS USB stick.
3. Boot from DOS USB stick

Ok, I'll do that you say. But I have a question. How can I create a .hsh (hash file) if I again receive message about no cpu hash?

I don't know algorithm for *.hsh files...

Try other method to update microcode.
Make DOS USB-stick (e.g, by Rufus), download and unzip all files for the modded version of CHECKUP7 to this DOS USB-stick.
Boot from this DOS USB-stick and make a photo of the screen with results.

That checkup loads microcodes only temporarily. I taken on second attempt to update a BIOS, by USB this time and I get the whole time error about no cpu hash file. I start to giving up.

This time I've deleted .hsh file and I see that is required file to update.

1. Download BIOS for ThinkCentre M55 and unpack it.
2. Copy 0106F7.PAT & 0106F7.HSH to your DOS USB stick with native BIOS flasher.
3. Boot from this DOS USB stick again.

Thanks. I'll do that not earlier than on Monday, because it's about my work computer. Even intelmicrocodelist.exe and MC Extractor says that is microcode for Q6600 (6F7). Should I leave a name 0106F7 or rename to 06F7?

Try to leave original name at first.
