MODBIN & MD8000 (MoBo: Medion MD5000 aka MSI MS-6701)

Well, got stuck! (again) :oops:

This is what I got

Code: Select all: CBROM V2.15 (C)Award Software 2001 All Rights Reserved. ******** md5k11b.bin BIOS component ******** No. Item-Name Original-Size Compressed-Size Original-File-Name ================================================================================ 0.

Followed the instructions as given by Nick in his answer to zhang yunhong and extracted all the modules and then release them.

For testing I recompressed the unchanged 6A7I0M4B.BIN (using lha255) to rebuild the BIOS image.
This gives a filesize of 77881 bytes instead of 77882 in the original BIOS image.

Cutted off those 77881 bytes from the stripped BIOS image and flipped the first remaining byte (value should be 0x54) to 0xFF to retain the necessary length of 184263 bytes.

Next I copied the parts together with

copy /b 6A7I0M4B.lzh+MD5k11B.bin neubios.bin

And at this point things get messed up. :evil:

Code: Select all: CBROM V2.15 (C)Award Software 2001 All Rights Reserved. ******** neubios.bin BIOS component ******** No. Item-Name Original-Size Compressed-Size Original-File-Name ================================================================================ 0.

Any idea?
Anyone can give me a hand and crosscheck that?

There is no need to do any changes to original.tmp.
Just decompress and recompress it using lha255, fix the size of the stripped BIOS image and put the parts together again.

Another thing I noticed was the following:
I used splitawd to extract all the modules (incl. 6A7I0M4B.BIN) from the original BIOS image.
This prog gives as well the compressed and the decompressed modules.
No prob to put the compressed 6A7I0M4B.BIN (00000000.BIN) back into the stripped BIOS again (though without the need to recompress it).

Do they probably keep some kind of (length) check sum in the very beginning of the BIOS so it gets messed up after a change?

Thanks ahead.

I then used MODBIN 4.50.80C to make a minor change to the startup string and updated the file. Now CBROM showed only one (BIOS) module in NEWBIOS.BIN.

Is this the missing link?
Just looks like!

So, now I can go back to where it all began:
What patches need to be done to make the setup entires visible :lol:

But, guys, you teached me a lot! Just like BIOS 4 Dummies!

P.S.:
During my extensive search for information on my problem I found some interesting tools on the net that seem to be not very wide spread - things like BIOS Update Utilities to patch microcode and stuff like that (Intel related stuff). Is it of any interest?
Guess not for me (at the moment).

Aha, it looks as though I compressed two steps into one in my description you linked to above - I will go back and correct it. Thanks. Good luck!

As I said (and you might see from this thread, I'm a bloody newbie to all of this :roll:

But all of you teached me a lot in this thread, thanx again!
(Apple, I just sent you a PM)

No prob, learned by doing.
Maybe it is also inflicted from my inpatience, should have read better.
Wouldn't it be a good idea to put all that knowledge together and to make a sticky out of it.
Noticed that some more had similar problems.
To bad that my English is restricted, no one would understand me

@ Edwin
Well, some greets to Edwin (evasive?) too:
The monkey tries to use tools to get the banana

Oops BTW, you know where I can find a flashing service in the Rdam area?

Good night,
Manfred

Back to work again

Well, it took some time till I was able to flash the BIOS.
Just had to wait for the RD1 to arrive to be on the safe side.

Flashed the new BIOS and - nothing but the BIOS Message has changed

Skip this subroutine with changing "xor cx,cx" to "ret"...

Apple, can you verify this, please?

And, wouldn't it be a good idea to change the routine at 1259Ch to just RET?

Oh, BTW, can you take a look at 0x17A1D - seen a call of this address many times in the source. Any idea what happens there?

THANKS ahead,
