Oh that's unfortunate. The only thing left to try is to either get a retail cpu and flash the bios via the bios or get a bios flasher which can flash via the SPI header on the board

Thanks. Maybe I can make the bios corrupt so it will initiate crashless 3 feature and flash from stick

Hi, It seems they fixed BMC firmware (new version is available to download) , I flashed old BIOS 0302 (Seems it's there according to BMC info) but it still stays at post code D1 (As I said out-of-the-box it was working fine with bios 0302) , could they blacklist ESes? No clue for now , also can't check with retail CPU , maybe mobo is bricked hard.

I don't think it's flashing the bios correctly. I had that issue as well

Not sure if it will help you guys but I just flashed a KNPA-U16 across to get support for the Z ROME ES processors and it is working well. I stopped at version 0302 based on the previous messages in this thread.
There is a bridge bios with PDF instructions here:
Why can't I boot normally with ROME series CPU? | Official Support | ASUS Switzerland
Haven't been able to find the exact same thing for KRPA-U16 motherboards yet but someone on here may be able to work out how to do similar for that model.

Oh yeah, you need a Naples Epyc processor to complete the procedure.
I bought a cheap one off Ebay and it worked fine. Probably best to do the same if you can't boot your Rome CPUs.

Do you have the 0302 UEFI File around? Cant find it in the downloadpage.

Good morning everybody, I would like to ask to @ExecutableFix and @yesoos if they fix the Asus KRPA bios problem?

I'm in a similar situation, I have:

- AMD ES ZS1406E2VJUG5
- 8 x 32GB Samsung M393A4K40DB3-CWE (3200MHz) or 1 x Kingston KSM32RD8/16MEI (3200MHz)
- ASUS KRPA-U16 shipped with 0501 bios


I try to flash the 0302 bios via ipmi (with /bios_update in maintenance tab) and it shows correct completition, but if i check again it show up the 0501 version again.
Then I bought a OEM cpu (AMD Epyc 7262) and the system boot fine (also windows works) so I decide to flash the 0302 bios via AZ Flasher and it looks there.
Now the real strange thing: Bios info shows 0302 version, AZ Flasher shows 0302 version, ipmi shows 0501 and I get D1 post error with the ES cpu; the oem one works great.

I'm looking for a solution because i'm becoming crazy!! Was someone of you able to resolve this bios problem? Can you please explain me how to resolve it?

thank you a lot and sorry for my english!

Goodmorning! I've also experienced a lot of weird stuff with the KRPA and the only way I was able to properly get a bios flash was via the SPI header. The D1 post code indicates that it's still using the 0501 bios. I know @EdwardTwiss was able to get it to work by flashing via the bios with a retail cpu, so that might be your best bet if you don't own a flasher

I have some flashers (stuff for Arduino, and motorcycle's ECU) but i have never flashed a motherboard's bios.
Can you please tell me the flasher i need to use and the exact (and detail please) procedure?
I saw a bios dump in the other thread and @Brainbug spoke about a CH341, is the CH340 good too?
Thank you

EDIT: @EdwardTwiss use an oem NAPLES to update the bios of a KNPA in order to make it working with the ROME.
It is a procedure design by Asus and they release a zip archive with all necessary stuff. This is another case unfortunatly.

I would recommend the elmor evc because of the included SPI cables that you'll need

Thanks man, at the end I did some homeworks, studied around the web and I figure out that I could flash my bios chip with a Raspberry Pi.
So I backuped my eeprom and then flash it with the dump file provided by @yesoos (I should give you a beer;)) with my Pi 3 and flashrom(dot)org software.

Now my ZS epyc finally works!!
