@Lost_N_BIOS

I've always added UUID/MAC with FD44 but I've never see (with hex editor) where is located. :(

Thanks @Sylar76 - maybe if no one else replies on this I can add it in that way and see where it goes, but since I'm rebuilding a broken BIOS (Or building one from stock or other dump) I need to see if it's original location matches where FD44 sticks it in there.
Using FD44 would be OK, but without a dump from same system I can't be sure which options should be used for the MAC Storage location, if it's at end of UUID or not etc. I really need to get a dump from someone, along with their details too, because sometimes UUID is in mixed format once put into BIOS.
Having that will help me find it's original location and it's format too, this way if I am forced to use a stock file or random dump, I will know exactly where it goes and how the UUID is formatted in if not straightforward

@shoukat2003 - what is your exact model and I'll find another users dump, then I can probably solve this myself! I have stock BIOS for K53D and K53J, but I assume there may be others too since there's both of those variants.
Let me know your proper full model and I'll find a working dump to use for my concerns and get this fixed for you

@Lost_N_BIOS

In case of Rampage V Extreme bios I've found via winhex that at offset 0x22100d there is the UUID written exactly as it appears on FD44Editor, followed by MAC address up to 0x22101c. At offset 0x221026 there is the Motherboard S/N written in hexadecimal format.

@Sylar76 - thanks, but I only need to know for @shoukat2003 exact system model. This kind of info varies in laid out into BIOS format and locations in all models and is often duplicated (Sometimes 2x sometimes 4x throughout the BIOS)

I'm sorry I can't help you mate. :(

Thanks for everyony here. I found only this mac address but i think it is wifi mac address and i tried it with no success.(although it is not my wlan mac ,may my wlan card is changed cause i bught used system). Thanks for everyone again for paying attention.

@shoukat2003

Please send any old bios dump of your notebook/laptop and I'll try to do my best to find out a valid MAC/UUID and S/N.

I have S/n. as you can see my uploaded pics. i want UUID and MAC.

@shoukat2003 - old.jpg is attached, got it If you want to upload files you can upload to any free file host and post link here.

Did you check on stickers inside casing, and on motherboard itself (especially near LAN port) for the MAC ID? Be sure to check under memory sticks too as I mentioned.
I can't fix your LAN without the LAN MAC ID. This will be on a sticker on your board, maybe inside the case, remove bottom and look at entire board and under memory, inside inner casing etc.

I tried to find in old.bin BIOS, but for now, can't find due to it's not kept in usual location in this BIOS, so unsure where exactly to look (Plus BIOS broken, so that makes is harder)
It may not be there anyway due to BIOS being broken, but we can check once I know it's usual location in this BIOS.

I found this info block 3-4 times in BIOS (one time only partial of some), but unsure which, if any is the MAC
B7N0BC276902291 = Serial I believe = 42 37 4e 30 42 43 32 37 36 39 30 32 32 39 31
90N3GPD34G2721VT30CU = 39 30 4e 33 47 50 44 33 34 47 32 37 32 31 56 54 33 30 43 55 << IF UUID, then 56 54 33 30 43 55 probably MAC ID
QTCKJA30E12905050 = 51 54 43 4b 4a 41 33 30 45 31 32 39 30 35 30

Maybe MAC 56 54 33 30 43 55 or 42 37 4e 30 42 43 (Two locations) or 51 54 43 4b 4a 41 / 56 54 33 30 43 55 (Four locations) - both are taken from above info
Hard to know, Asus switch this up sometimes, sometimes mac at end of UUID, other times not, and sometimes UUID is mixed up in certain ways in BIOS too. Need source dump from same board, with known correct MAC ID In place to really be sure.

@Sylar76 - do you remember where/which module UUID or MAC is stored in this BIOS? I see MAC is kept within UUID only from Fd44, so I assume like many Asus MAC is at end of UUID

@PsyduckAP - can you send now working corrected dump with your MAC ID left in place, and tell me the ID, so I can find proper location to fix MAC for above user if Sylar76 is unsure of location.
@Nilpo - same as above, or can you tell me the exact hex location, or BIOS module etc, then I can see if I can find users ID from his above bricked dump.

@Sylar76 - see post #30 I posted all the info I found, the dump is corrupted in some areas. I found a good dump, most info other than NVRAM is found at 20000h and 28000h, but none there but FF and some short incorrect data.
Secondary locations info I posted on #30 at 220000 + 280000, this is good info I think (but getting MAC tricky)
If you can confirm/decipher the rest of what I posted on post #30 that would be great, I think it's maybe correct info I just need to put back into correct locations and in correct format/order as far as system ID/Details, still need to find MAC location so I can put back once found/confirmed.
Serial is correct, so I assume the rest is too, just need to find MAC and redo BIOS. I also now see QTCKJA30E12905050 confirmed on his stickers, so this probably UUID or DTS key (17 char though, so I dunno, but since it's on sticker and in BIOS it's one of those ID's I'm sure)

@shoukat2003 - thanks for all the images. I think that one should be your MAC still, since you changed cards, that's attached to the new card correct? It looks like heatsink attached to the card, so that should be correct, but that is wireless/BT as you mentioned, not Ethernet/LAN
Edit your post and blur or remove that sticker that shows your windows key

@shoukat2003 and @Lost_N_BIOS

Well, I think I've figured out where info are stored and I've reconstructed whole bios (bios region + me firmware) with UUID/MAC and Mobo S/N.

Please try it and report feedback please.

If it works I'll share info

Yes, please let me know MAC and if it was in the pile I posted on #30 thanks @Sylar76 - and thanks for jumping in to assist too

According to old.bin backup bios (corrupted) sent before, it seems that the MAC Address is the same as reported in the label near the wifi module (which has a different BT Mac Addess).

Other info, like QTCK..... is a name code regarding the SODIMM modules. System UUID is a sort of GUID written in little endian which can be got via command prompt typing "wmic csproduct get "UUID"" (without first quotes).

Anyway, it's not needed in order to have LAN working, as UUID is strictly related to the Windows system activation (OEM/SLIC or Microsoft database for embedded keys).

What makes LAN to work is the MAC Address + a valid ME firmware image (and of course me drivers). Sometimes, removing and adding lan controller from hardware management console (in Windows) fixes this issue.

Anyway, let's wait for @shoukat2003 if he's able to flash my bios image and see if it works.

Edit : You can open my attached bios image with FD44Editor, as well as with UEFI Tool.

Edit 2 :

This is another trick for writing a MAC Address on ASUS Laptop computers (under pure dos environment).

1) Uncompress zip file and copy bt.exe on the root device (I assume to use an USB stick formatted and dos bootable).

2) Let's suppose to use a MAC Address like this : 14-DA-E9-5B-1B-04

3) You'll have to use the following syntax :

bt.exe -C CNFG / W C2 14
bt.exe -C CNFG / W C3 DA
bt.exe -C CNFG / W C4 E9
bt.exe -C CNFG / W C5 5B
bt.exe -C CNFG / W C6 1B
bt.exe -C CNFG / W C7 04

bt.exe -C CNFG / W D7 14
bt.exe -C CNFG / W D8 DA
bt.exe -C CNFG / W D9 E9
bt.exe -C CNFG / W DA 5B
bt.exe -C CNFG / W DB 1B
bt.exe -C CNFG / W DC 04

4) Reboot and see if Network card is working.

Thanks for the info on the MAC Stuff @Sylar76 - UUID can't be grabbed with WMIC due to bricked BIOS, we have to get out of dump if not corrupted too, that's why I asked if you can tell if UUID on post #30 or not
Or maybe it's this one, MAC Often at end so maybe this one is correct 51 54 43 4b 4a 41 33 30 45 31 14 da e9 5b 1b 04
I see that MAC in BIOS now too, thanks! I thought it was corrupted data there before, when he hadn't shown us that image yet. Now all is there, I bet your BIOS works fine! Thanks again

* Edit, I thought I recognized that tool, it's also used to fix keyboard backlight when killed from BIOS Flashing
Correct command to fix the keyboard lights >> bt -c cnfg /w dd 7c

@Sylar76 and @Lost_N_BIOS i am very very thankful for both of you. as i have assembled my laptop so first i tried BT.exe and its done. I thought if i fail then i try to flash the bios file. but Thanks GOD i have done successfully with your help. my lan card is perfect now. Thanks A lot.
