Nope on the 64MB version, and I don't think it's CSM after all, it might be something else in the failsafe values that take effect after a bios update etc.

Crazy right? Sadly the board is EOL so I doubt they will fix it. I chased 4.04 for months until it got released. I wonder why it just hangs with CSM on Milan though.

I already had access I upgraded from Rome and everything was set up. Yeah well I cleared CMOS multiple times and removed the battery but it kept loading in old-school CSM mode.

Yup and it flashes everything without validation! Yes im on an AMD platform but this driver is a PXE boot thingy from the onboard Intel nic.

Nope it goes from BMC straight to The Intel Boot Agent which gets stuck on my machine and even if it succeeds I never got to the bios.

Upgraded to Milan (7443P) from Rome (7302) and reset CMOS, the CSM got enabled and on my bios 4.04 it prevents booting! It almost bricked itself (can't enter bios, BCS it never shows) Managed to set CSM to disabled using redfish, but jesus I wasted 6 hours on a simple CPU swap. Be careful when...

New Bios and BMC is out by the way :)

Is the baud rate correct?

Yup thats the port you need to connect to. Buy a cheap USB->UART adapter (e.g one with the CP2104 chipset) and some "gpio" wires e.g for a raspberry pi and try the following. Install a serial client like tio on linux or putty on windows and open the serial connection to the adapter (115200...

I don't think this is the same as the internal debug BMC header but it can't hurt to test this port too, feel free to try. But I was talking about the internal 4 pin header. If you need help with that I can provide some details.

You could attach an UART Adapter to the BMC Debug port and see if it boots up, but only use this as last resort if the seller can't help. I don't think the board is dead, it's most likely the BMC that is corrupted.

Wilfredo Uy (@Tyan) provided me the command required for the 4.11.0 BMC Use the following for fan control on this version: ipmitool -I lanplus -H YourHost -U root -P '' raw 0x2e 0x44 0xfd 0x19 0x00 0x05 0x01 0x64 Where: 0x05 is the PWM id from the list attached below in hex from 0x0 - 0x5...

I have 3 sys fan sensor values and 1 cpu in the BMC i will just check tomorrow. I tried all ids from 00-05 Edit: No difference must be something with the newer BMC versions?

I will, currently the system has no ram and im waiting for the shipment.

ipmitool -I lanplus -H 10.0.1.169 -U root -P 'mypassword' raw 0x2e 0x05 0xfd 0x19 0x00 0x03 0xfe

Hey im getting Unable to send RAW command (channel=0x0 netfn=0x2e lun=0x0 cmd=0x5 rsp=0xc7): Request data length invalid when trying to read the fan speed like outlined a few pages before. Im running the latest BMC, any idea?
