ASUS KRPA-U16 full BIOS dump request

[RolloZ170]

Are you sure?

NO

OK. the SPI1 was used by Gabber to flash the BIOS. and on the KNPA-U16 is a 8 Pin 16MB chip instead of the 16 pin 25q256.
looks indeed this is the BIOS chip but where is the BMC FW chip ?
All BIOS files are 16MB in size CAPs. there is no way to flash the bare CAP into the chip. for that reason the SPI1 near the chip is ASUS nonsense.

I don't know where exactly the BMC chip is but I know that you don't flash CAP. As mentioned before, here in this thread, you use UEFITool to extract ROM and then flash it. That is my plan.

mhh sure as i mentioned.
WHY does ASUS make SPI1 header which can not be used because ASUS do not provide flashable files ?

It's for their own use or for the service use...

And it's not just ASUS. MSI, Gigabyte, ASRock does the same. Even XBOX had this, called JTAG...

SPI-header pinouts

EVC2 SPI-header (2x4-pin 2.54mm pitch)The pinout is for reference also printed at the back of the PCB. This is a standard layout matching most SOIC8/DIP8 SPI …

Gigabyte provide Flashable files.
JTAG is for completely different usage.

Gigabyte is also switching to CAP... Gigabyte...Enable Secure Boot and brick the motherboard. Told them about this problem months ago, still no update. Gigabyte and MSI are second players.

sure. like supermicro, the end of DOS flashing and BIOS modding.

 

[RolloZ170]

by the way: with Supermicro & Gigabyte,ASRock you can update the BIOS with the IPMI GUI. ASUS not ?
Gigabyte boards for Rome have a 32MB BIOS chip with Rome in the first 16mb and Milan in the second 16mb of the whole 32mb chip.
just a therory: is it possible to remove the 25q256 chip and populate the 8 Pin Socket for a DIP BIOS chip ? sure then you have only the BIOS for one EPYC gen, not two.

pls elaborate !

As long as there is BIOS Flasback, I don't care much.

Normally, you can do that via BMC Web GUI but in this case, you have to have an old CPU which is a bummer.

I am not sure about that.

Secure Boot açtıktan sonra sistem açılmıyor

Arkadaşlar merhaba, Secure Boot açmak için BIOS'a girdim ve açtım sonra "platform key" ayarını Update yaptım ve kaydedip yeniden başlattım ama PC şimdi açılmıyor sürekli reset atıyor gibi. Çözüm olarak BIOS pilini çıkardım ama düzelmedi

Yes it does but you can't update to Milan BIOS via BMC web GUI. If I could, I wouldn't be here at all.

LOL, ASUS not better than Gigabyte.

You keep believing that bro.

the GUI rejects the Milan BIOS ? if so do you have the latest BMC FW ?

 

[cool_recep]

I can't even reach BMC GUI as it requires a second LAN connection somehow. I connnected it but still no luck. Even if I could, the BMC update notes that you have to use DOS interface:

KRPA-U16 Upgrade BMC Firmware to 2.0.6 version | Official Support | ASUS Global

 

[RolloZ170]

Even if I could, the BMC update notes that you have to use DOS interface:

yes. sorry, my fault

the dedicated LAN port is the RJ45 over the USB ports. should be DHCP by factroy default.

It is DHCP and I can see the IP but it does not respond when I try to reach it via browser or explorer. I have two options:

• CH341A
• Raspberry Pi 4

I'll try them this week but it would be nice if someone provided better pinout information. I asked ASUS and I'm waiting for their feedback.

i have a third option: RMA to ASUS and ask for Milan BIOS.
not normal the BMC is not working. Heartbeat LED flashing ? waited long enough ? takes 2 minutes to respond from powerup.
Web GUI connection is not safe(not ssh)
