S8036GM2NE-LE with 7642 Cpu very basic bios and BMC options

[portzero]

that is what i meant. but the change is not persistant to BMC reboot right ?

Its persistent, that is the file where the fan curve is set and all changes are permanent so make sure you create a copy of it before making the changes so that you have a reference point.
Let me know you wan't to achieve and i can direct you on the changed you can make to achieve that goal.

thanks, i was in hope i can do same with supermicro X14 OpenBMC, but i got only SSH to SMASH CLP Shell which does not allow me to see usr dir.
only system1/sensors1...

i you can still use ipmitool commands to set fan curve on supermicro
i did that recently just ask gemeni or claude

do not work for X14. so far, anything changed with OpenBMC.
i can not access the BMC by ipmitool, while i have normal access to BMCWebGUI with other PC.
i can use saa.efi (new SM tool) to send raw cmds, but which is not investigated so far.

Hi All,

I've been messing about with replacing the BIOS and BMC IC's.
I was trying all this to see if there was a way to
a) get the full BIOS so I could try and get an OCP 2.0 MCX545A-CCUN card working in the machine.
b) see if it sorted out my M.2 sensor temp of 0.37 degC issue which caused the fans to hunt
c) give more control in both BIOS and BMC

I removed the old IC's, and replaced with new IC's flashed with the latest bios and BMC for the S8036, using this forum thread for reference.

new BMC version = 4.04.0 (needs a 64mb IC rather than the old 32mb IC)
new BIOS version = 2.06
Download

Case 1: Both new BMC and BIOS IC's installed.
System doesn't finish POST. I get the Tyan POST graphics, but the POST gets to "OEM pre-memory initialization 0022" and hangs. I tried with memory only in DIMM A1, and then memory in DIMM's A1 + C1, and then also DIMM's A1 + E1, but always the same error.

Case 2: New BIOS but old BMC IC's installed.
Same issue as Case 1

Case 3: New BMC but old BIOS IC's installed.
System posts and works. Fans are nice and quiet. Issue is that the new BMC needs the MAC address for its NIC to be hard set, otherwise every time you hard reset or restart the BMC, a new random MAC address is used for it (MAC address is not persistent) Fine if you run DHCP and don't care about this.
I tried setting the MAC with sudo ipmitool lan set 1 macaddr <xx:xx....> but it would not stick.
Another thing is there is no option to turn on SSH to access the BMC, which you can do with the base Hyve BMC.

I also tried updating the BIOS via the new BMC, but this just puts you at the Case 1 issue.

Outcomes

The only positives that Case 3 (the only usable case) produced was the fans were a lot quieter, and the M.2 sensor temp issue was resolved.
The MCX545A-CCUN card still was not recognised by BIOS (because the BIOS couldn't be updated), and the BMC nic MAC address could not be set to a static persistent value.

Perhaps peoples with more experience can chime in with constructive things I could try and report back on.

(This has also been posted in another STH forum thread dealing with these servers)

BIOS/BMC same chips (vendor, BMC 256>512) ?
erased chip, blankcheck, write, verfied ?
Status/CFG bytes flashed as old chips ?

Yes exact same chip and manuf just 512 instead of 256 for the bmc.
1x off protect, 2x erased, 1x blankchecked, 1x write, 2x verified.
You will have to explain what you mean and how to flash the status/cfg bytes from the old chips.

read read the status/cfg bytes. you need to write same,
e.g. QE=1, buffer strangening and so on.

you flashed the 32mb ROM right ?

 

[RolloZ170]

BMC needs the MAC address for its NIC to be hard set,

can you flash the OLD BMC content in the new 64mb chip ? maybe then flash/upgrade by EFI shell preserves BMC MAC.

 

[Ulgracht]

I flashed bios v2.06 from the website to a new 32mb chip
I flashed BMC v4.04 from the website to a new 64mb chip

I have put the old BIOS and old BMC chips back in the server for now - which is another problem as the sensors are no longer showing up in the old BMC, and fans now run 100% all the time.

 

[RolloZ170]

I flashed bios v2.06 from the website to a new 32mb chip

there are two CAP, a BIN and some other files.
or you flashed the zip ?

I thought that flashing a 32mb rom image to a 64mb chip wasn't possible as you left all that empty space.

I used a CH341a to write the BIOS v2.06 8036V206.ROM file to the new 32mb chip. Same for the BMC 8036020404.ima file to a new 64mb chip

 

[RolloZ170]

the new 64mb FW uses only 32mb of chip, there is only 256 bytes in the 2nd half.
just try. fill 2nd 32mb with FF (HexEdit)

You're talking about the BMC chip here correct?

 

[RolloZ170]

yes.

 

[Ulgracht]

yes.

I went and wrote an image of the old BMC 32mb chip to a new 64mb chip, and installed that in the server.
The 64mb chip with the old BMC 32mb image was working, but with no sensors - SDR table needs to be fixed).
The BMC webgui wouldn't let me flash an image of BMC v4.04 (64mb) over the old BMC 32mb image on the 64mb chip.
I also wrote the old BMC 32mb image to a spare 32mb chip and installed it in the server.
I then tried to reflash that new working 32mb chip with the old BMC 32mb image just to see if the webgui flash actually works, but it did not.

 

[RolloZ170]

i sayd you need EFI or linux socflash

webgui flash actually works

in the readme of BMC firmware. only socflash.
