Yes im on an AMD platform but this driver is a PXE boot thingy from the onboard Intel nic.
tyan must be the only motherboard without BIOS access over 15pin VGA with fatcory settings (CSM on) then, strange.
clear CMOS should force to BIOS in any case.

how got you BMC access without BIOS access to create a user ?
BIOS defaults of 4.04 are very inconsistent, Secure Boot is enabled Failsafe,
in that case CSM should not be active even if enabled.

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.

yes i see now, in BIOS V4.04 are two BIOS, Rome and Milan with diff.default settings

Rome BIOS: Sec.Boot: enabled/disabled (failsave/optimal)
Milan BIOS: Sec.Boot: enabled/enabled (failsave/optimal)

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.

Are you running 4.04 on the rev 1.0 of the motherboard? (ie the one with the 32MB BMC chip) ?

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.

Hi All, buyiing this board in a few days. Can anyone recommend memory and the cheapest place to find it?

I found this ::
Kingston 16GB PC4 3200MHz Server RDIMM RAM 2Rx8 KSM32RD8/16HDR

But the kingston site says it doesnt work - i guess because its not ECC?

I got 8x 32gb RDIMM of Micron 36ASF4G72PZ-3G2J3 that is on the compatibility list over 2-years ago and paid in the neighborhood of $80/module. I got some on eBay and some off ServerMonkey. Checking today and those same modules are going for $250+. Sorry.

i guess the Hynix D die with 'R'ambus RCD does not work good with EPYC and they do not recommend.

KSM32RD8/16HDR is EOL
maybe for that reason...
edit:
ASRock - Server 1U10E-ROME/2T is compatible, and more ASRock SP3 boards.
the list of compatible ones includes only letter 'A'

the compatibility List sucks

For everyone who is also looking for this. After ~11 days I finally received the answer from Tyan support:



Get/Set PWM Duty

0x2e 0x5 0xfd 0x19 0x00 <PWM ID> <0x00-0x64|0xfe|0xff>

Note:

PWM ID : 0,1,2,3,4,5

0x00-0x64 = 0 -100% duty

0xfe =Get Current PWM Duty

0xff = return to automatic control


For example:

To read current PWM duty cyle:

ipmitool -I lanplus -U <BMC IP> -U root -P <YourPassword> raw 0x2e 0x05 0xfd 0x19 0x00 0x03 0xfe


To set PWM duty cycle to 60 on PWM ID 0

ipmitool -I lanplus -U <BMC IP> -U root -P <YourPassword> raw 0x2e 0x05 0xfd 0x19 0x00 0x00 0x3C

What even more you can control EACH PWM SEPARATELY
Thanks for this! my proxmox host doesnt have ipmitool, when i issue apt install ipmitool the syntax is different. Can you let me know how/where you installed this tool? Thanks

I am now facing a Similar problem

I am seeing 00AD DEAD 0000 CCCC after trying to update the bios / performing CMOS reset

It originally was on v300 with epyc 7282 and 3x 64gb Samsung rdimm 2933, but i can not get it to boot anymore

Flashing any other version of bios didnot fix the issue.


Additionally the first flash i accidentally flashed the .zip instead of just the .rom file which resulted in FFFF but i was able to resolve that using the webflash of bios .rom file

Do you think this couldve done more damage thats not visible? (i also cant seem to be able to flash a bios using the bios recover option -> ctrl home leads to it saying starting recover but it ends the same with the DEAD Code)


Appreciate any help!

but i was able to resolve that using BMC flash of .rom
file for BMC flash is *.hpm
i am surprised it accepts a zip file.
if i do that on ASRock Rack LGA4677 intel platform i can't flash BIOS anymore because this process need a functional ME/SPS machine working in the chipset. maybe AMD have similar situation and you need to flash with SPI programmer(test clamp or soldering)
