[solved] Can asus NB frequency be unlocked or added? amd mobo m3a78-em

[Antinomy]

I'm not a programmer so I can't help with anything related to disassembling. Maybe one day I'll go in assembler because BIOS mods are interesting but now I'm a noob in this. All I need is the address and a bit of luck (that they just disabled the option but didn't cut it off).

I must admit that you are a good example of a topic starter - not a lazy one but an active one - looking for options and ways. I appreciate that

Check this one.

If this one doesn't work then making the option you need will be much more complicated yet not impossible. We'll just have to use extra tools.

YOU DID IT !! hahaha

NB frequency works now. You successfully added a feature to the bios.

just out of my own curiosity, did you use any existing bios strings ? if so, which ones? Or did you import them from the very oldest bios rom?
I could not find the exact strings you used based on the multiplier options you put in.

could you give some hints as to your tweak process for this bios ?

Major thanks.

Thanks. You did almost (maybe a bit less, maybe a bit more) than half of the work in fact. I mean especially the find about earlier BIOS which gave me the answer (after some torture ). And a BIOS from another board was a good catch (though, I came to the same idea a bit earlier and implemented in the first attempt).

All the strings I used are existing ones. If you remember the 4x, 5x and so on multis - it's them. But as I understand there's a code that multiplies these multipliers by HT clock and gives you the summary NB frequency. This is done to show you the correct frequency when you overclock. So if you set 2000MHz in NB frequency and set HT to 220, the NB will show 2200 in the menu? Well, this is what I've ment.

But the feature that replaces multipliers with NB frequency didn't work until I linked the menu to the right CMOS index. After that the magic worked by itself. I didn't add it, I've just unhidden it.

I'm very glad that this worked - I've seen such a BIOS string replacement feature for the first time and wasn't unsure that got how it works right. Thank you for your activity and enthusiasm too.

I think I'll make a tutorial for such things soon.

Why is the zip corrupted? -.- Can´t unzip it without error ( not a valid zip-file)

[Antinomy]

You're right. I'll re-upload it and repost a working link.

[blechfisch]

That would be great! Thank you very much!

Please don´t forget me Antinomy.

Thank you Antinomy for your efforts.
Could you please upload a working copy of the file, so we can have it too?

I tried to fix the .zip file:

Code:

$ zip -FF finish_2.zip --out finish_2_repaired.zip
Fix archive (-FF) - salvage what can
    zip warning: Missing end (EOCDR) signature - either this archive
is not readable or the end is damaged
Is this a single-disk archive? (y/n): y
Assuming single-disk archive
Scanning for entries...
copying: finish_2.rom (750539 bytes)
Central Directory found...
    zip warning: reading central directory: No such file or directory
    zip warning: bad archive - error reading central directory
    zip warning: skipping this entry...

The resulting .rom seems to be intact (1048576 bytes; mmtool and amibcp can open it), but I don't own this board.. be careful.

Antinomy, nice job! You didn't write something like a tutorial yet, did you? I'm trying to figure out how you did this because I'm in a very similar situation.. I need to change the command rate (1T or 2T); the BIOS strings are there, but no option. I'm fooling around with amibcp, mmtool and a hex editor (same things you used?), but I don't know how to add a menu item..
