I recently bought a Acer off-market engineer motherboard which powered with a J5005es CPU and AMI Aptio V UEFI BIOS. It is similar to Acer Aspire XC-830, the only difference is mine has two HDMI ports, HDMI IN and HDMI OUT. I downloaded latest XC-830 BIOS file and tried to flash with afuwinx64 but failed. It says wrong ROM ID, I tried to flash with /X option which reports secure flash verify fail error. I also lost MAC address of Realtek GBE controller even though I can.manually add MAC address to make it work, the BIOS Realtek GBE controller shows 00-00-00-00-00-00. Any suggestion on how to make a moded bios XC-830 BIOS and flash to my motherboard? My motherboard also cannot boot Freedos tried legacy boot but the monitor goes blank after.choosing the mass storage boot. The mb has WP1 OBR1 TXE1 jumpers that I have no idea what they represent. I also tried backup with afuwin64 /O command but still fails to flash the backup BIOS file, still secure flash verify fail error shows.

My mb txe1 has 3 jumper pins, I`m not sure whether I shorted the pins right. Here is the output.

Thank you for your effort. I will try to flash with SPI programmer and report back. The bios chip w25q128fwsq is covered by plastic cap.vB.t.w., can I use CH341A SPI programmer and flashrom to flash w25q128fwsq chip?

The back side of the mb also has a Winbond chip shows below.

For W25Q128FW you need to use ASProgrammer 1.40 and you'll need 1.8v adapter like this - https://www.ebay.com/itm/202046860676

I tried dump mod and R01B0 mod bioses, with HDMI monitor they all work, but with VGA none of them worked. Both cannot boot with secure boot option enabled at first boot. The Realtek GBE ethernet controller also shows 00-00-00-00-00-00 hardware address in OS. A strange things is the buzzer of the mb will not beep with original bios, but with the mod BIOSes they both beep during power on.
The dump mod bios shows below.

Both mod bioses can not boot with VGA monitor and shows secure boot signatrue error. Realtek GBE ethernet controller seems has no MAC address. Options in mod BIOSes seems a lot trimmed comparing to the original BIOS.

P.S.
I can boot with Secure boot enabled after first boot with secure boot disabled. The major issue is the VGA boot blank screen and the 00-00-00-00-00-00 MAC address of Realtek 8111GA.

You can fix MAC ID. Do you need secure boot mode? If yes, then you may need to change some BIOS settings, and I'm not certain but I think there may not be such a thing as a secure boot enabled VGA BIOS (legacy option rom is used for this... Legacy = non UEFI = Not able to do secure boot)

To fix the MAC ID's, you need to find the MAC ID's on the board/inner casing, often on a sticker or on/near the LAN ports, if not check both sides of the board for all stickers and the inside of the casing. Also, check on/around/beneath the memory, sometimes sticker is hidden there too.
If you already know the MAC ID's then post them here and Plutomaniac or I can put back into BIOS for you possibly (may not be stored in BIOS). See this thread, try changing with that tool and be sure to read last post about realtek ID's - https://forums.lenovo.com/t5/Lenovo-P-Y-...00/td-p/1817289

Thank you for ur reply. My mb LAN ID is 98eecb5737e5. It would be nice if you can inject this MAC ID into the bios file.
B.t.w., my mb has a 13-pin socket, I have not figured out the rest rest of them except the HDD LED and PWRBTN locates.

I fixed the audio problem by replace the ALC662-VD0 chip. I dumped the SPI. I will upload the CH341A backup of my BIOS chip if needed.

I cannot fix the RTL8111GA MAC Address 00-00-00-00-00-00 issue with traditional tools, even contacted ASROCK service support, they send me a APP called wMAC which runs on Windows but it cannot write MAC address of RTL8111GA chip.
I need my BIOS with updated CPU Microcode and REALTEK LAN UEFI driver. The peer of this motherboard goes with ASPIRE XC-830, I think we can adapt from XC-830 and make some change especially the CPU microcode and add back to the original BIOS dump, or mod the XC-830 BIOS according to the BIOS dump. The mod @plutomaniac did work out of box except it cannot boot with VGA monitor. The mb has two HDMI and a VGA output comparing to the XC-830 which has a HDMI and VGA output.

After replacing the broken Realtek rtl8111ga chip, I lost LAN MAC address. The motherboard powered with a J5005es CPU and AMI Aptio V UEFI BIOS. BIOS and Windows 10 shows Realtek GBE controller has no MAC address assigned, simply 00-00-00-00-00-00. It is similar to Acer Aspire XC-830 which has a HDMI and VGA output, but this mb has two HDMIs (HDMI-IN, HDMI-OUT) and a VGA output. The BIOS is a 2017 version, is it possible to extract CPU microcode, SATA, Realtek UEFI Lan Driver, etc of the XC-830 BIOS and inject to mb BIOS? Or is it possible to change the XC-830 BIOS to the adapt the mb?

BIOS backup by CH341A programmer, it is slightly bigger than SPI bin.

Merged your new topic back into this one - no need for two threads, and I already replied to you about this exact issue here

@wizbee - Please use some other non-virus upload site. That site sets off malwarebytes 4-5 times with different warnings of things being blocked, and I cannot download the file without having that "With addons" box checked
This is a good site for file sharing - http://tinyupload.com/

Never mind, got it finally!

* Edit - I cannot find MAC in this BIOS, since you currently only have zeros as your MAC ID. The only way to find it in BIOS, is to have a dump from another same system, and know it's exact MAC ID

So software for now will be the only way, unless you can resolve above mentioned situation

Download the stock XC-830 package, extract, in the Win folder, try this command for AFUWin to fix MAC (may not work, but we start there) >> afuwinx64.exe /M 98EECB5737E5
If that fails, try one of these tools and the following commands, from DOS

dmi236.exe /o 98EECB5737E5
dmi172.exe /o 98EECB5737E5

If those fail, try EEUpdate from Intel (included above link) - here's a how to PDF, in case you have two MAC's - http://advdownload.advantech.com/product...C%20ADDRESS.PDF
EEUpdate.exe /MAC=98EECB5737E5

If those all fail, also included is Asrock MAC Write package, which includes two specific tools for RTL8111

Thanks for your reply. I just backed up the BIOS with CH341A programmer. Please check it out.

P.S., I cannot boot into DOS environment with this mb. Tried legacy boot still fails. So DOS tool is no go. Can you help me mod the BIOS that include the CPU microcode, Realtek LAN EFI drivers(EFI BIOS modules upgradeable with XC-830 BIOS and UEFITOOLS) updates of the XC-830 BIOS, btw onboard CPU is J5005ES comparing to the J5005 of XC-830.

---------------

Thank you for you BIOS mods, I tested both of them and all runs with lower CPU percentage resources at startup and seems cooler than the original BIOS. But VGA output is not working. My mb has HDMI-IN, HDMI-OUT, VGA but the XC-830 lacks the HDMI-IN. Is it possible to mod the original BIOS to include the latest EFI BIOS modules and CPU microcode using XC-830 latest BIOS and the UEFITOOLS? Btw some mods need to adapt the J5005ES CPU.

----------------------

I have a ACER XC-730 which has the same rtl8111ga and similar BIOS except it is powered by J4205. Should I upload this BIOS for you to pin down the problem?

@wizbee - thanks for your BIOS dump, but didn't you already give that before? You can boot to DOS, you just need to make DOS bootable USB or CD, then choose that via bootmenu hotkey at startup, or set those to be first in boot device list in BIOS temporarily
Yes, I can update CPU microcode for you, and LAN I suppose but that is only useable if you boot to LAN via PXE (This is all the BIOS LAN Module is used for)

I did not upload any BIOS, so I'm not sure what you mean about you "Tested both BIOS mods"??

As for the ACER XC-730 BIOS, yes, that may be helpful to find MAC location in your BIOS for the XC-830, if it's stored in same or close location.
Please give me programmer dump from XC-730 and tell me if's MAC ID. If the MAC ID is not in it's BIOS, then it's stored in chip, and you'll have to use one of the tools I linked you to in package previously.
