I'm not aware there is another way than direct programming ob BIOS chip, but surely if someone knows how, I would be very thankful for that information.
Spent whole night with it, but finally was able to flash latest Supermicro BIOS without desoldering. I don't know if there is problem with Linux or programmer SW, but only way I made it work was on WIndows and with Neo Programmer.
Well, looks like even with CH341A I can't bypass write protection.
sudo ./flashrom --progress --programmer ch341a_spi -w BIOS_X11DPU-091C_20240305_4.3_STD.bin
flashrom v1.5.1 on Linux 6.11.0-25-generic (x86_64)
flashrom is free software, get the source code at https://flashrom.org

Just bought few SYS-6019U-TN4R4T with X11DPU. Same problem as @XeonSam have. Tried everything except CH341A programmer. I was tempted to try it too, but then I found out I have 5V version, not 3.3V I need and with my eyes I'm unable to modify it. Ordered new v7 with voltage switch, will see...
I tried ARCTIC Freezer 4U-M Ampere, because it has proper airflow (to the back of the case, not up), but it won't fit, even though it should be compatible with SP3 specifically. The metal mounting parts go too far from socket and there are on-board components under them :( It's shame, I really...
Didn’t had time for this lately, but I’m not finished yet.
