1.- received computer with wrong bios (3020 desktop), then i tried fix flashing extracted bios.bin and then (i killed it) black screen
2.- with a ch341a programmer flash this rom: https://vinafix.com/attachments/optiplex-3020m-a15-bin-zip.108074/ of here and not works, system power on but without video.
3.- Download 3020 A15 rom from anywhere (for tower model) flash it and works partially; system boots, but missing ethernet, and several errors or alerts at startup.
4.- Tried update or flash the correct bios version with official utility but is not possible because says "this rom is for different model"
5.- I want only flash the adequate rom for my computer DELL 3020M Micro, thanks
 
tested

**** MANUFACTURING MODE ACTIVE ****

its revision 3020 A20 but same errors and again no ethernet, the mac info in bios is filled with FF´s

if no possible fix ethernet device y startup errors, at least you can help me to hide this errors?

-remove alert for rear fan (the 3020m only have a cpu fan)
-remove alert about front I/O cables
-reduce time before of DELL boot screen (hangs about 1 minute)

Thanks
 
You do not need to care about the ultimate purpose version is the working PC

1. Not working PC, for that i paid you for support.
2. The ROM https://vinafix.com/attachments/optiplex-3020m-a15-bin-zip.108074/ is NOT full A15 version because Intel Me version is 9.1.0.1120 while the A15 version (from DELL) have 9.1.37.1002
3. Ethernet device not was working because ME version; with UEFITool extract Me 9.1.37.1002 region from A15 bios and replace in the 3020 Desktop bios (without M), flashed it with flashrom and now ethernet is FIXED.

no problem 3020 or 3020m only need it same motherboard code.

NO, almost same code therefore there is a different bios for each.

Still investigating over remain issues:

-remove alert for rear fan (the 3020m only have a cpu fan)
-remove alert about front I/O cables
-reduce time before of DELL boot screen (hangs about 1 minute) FIXED too
