you have to ask and beg. but they mostly don't have BIOS.
i can't find a reason why those BIOS are not officialy on the motherboard page, there is only in my case a two years old BIOS with bugs and vulnerabilities.

Most of the ones in the FTP are not production builds, they haven't undergone the same level of testing as the ones they will publish on the website. Some are even custom builds branded for specific companies, or with specific featuresets requested by those companies.
Which board model do you have? I can check on my side and see what's available for it.
thx
SPC741D8UD-2T_X550
on site is 10.13 5/15/2024
last new is 11.09 - 28.08.2025 (i asked ASRock for BIOS with solved last known vulnerabilities (AMI BIOS etc)
but again: why are those secure important BIOS not public available ?
The latest version on the FTP is currently 11.10.AB02, with date 11/25/2025. Though it is under the "special" folder in the FTP so it was likely compiled for a specific provider.
It seems like they may have also created a bit of confusion internally, as there are two folders, one is "SPC741D8UD-2T-X550" and the other is "SPC741D8UD-2T_X550" (hyphen versus underscore) - both appear to be the same board, but with different versions scattered throughout both folders.
Do you have the email contact for William? He can usually dropbox you the latest builds within an hour or so.
this is only for OEM motherbaords.
sure. i got the FTP access to the new 11.09 BIOS.
but still not available at motherboard site. why ?
Asrock has always been terrible at updating their website, some of it can be excused by saying they don't want to publish beta builds that could brick boards. (but they have done that anyway)
I will say they are more responsive to providing builds for issues quickly compared to supermicro though. But they also have more bugs in general it seems than supermicro.
A bit off topic, but for those wanting to access the Java iKVM without too much hassle, I just managed to get 2 Ways of it working, both based on this Docker Image (read the Issues Section if you try to build the
github.com
Combined with Authentik Identity Provider (Self-Hosted) you get:
Via Authentik RAC
Via Docker Container noVNC (after Proxy Authentication via Authentik)
Not super Memory Efficient unfortunately
Around 453 MB of RAM used.
Granted if you are happy with the Proxy + built in noVNC, you can shave off 95 MB of the Authentic RAC Outpost Container, down to around 358 MB.
My plan now is to see if I can take advantage of Proxmox VE Kernel Samepage Merging (KSM) to reduce the Memory Usage in case of spinning up multiple Instances (1 for each Target Server). Unfortunately even the smallest VM (Alpine) sits at around 400MB Disk Usage without even spinning up a Container. LXC Alpine would be 100 MB Disk Usage with Podman installed and ready to go, but unfortunately KSM doesn't seem to work with LXC Containers (across User Namespaces)
.
Disk Usage vs Memory Usage I guess.
Probably better to just turn these on on-demand, although that would require some other kind of control Method via SSH or similar.
EDIT 1: if desired, maybe better to move to a separate Thread ?

i was able to convince my retailer to
contact the distributor
who contacted supermicro europe
and then the changelog was provided ...
also it is actually not possible to get
sm mainboards at all for my retailer here
in germany. the distributor told us after
asking for availability of sm mobos that
sm is not interested anymore in selling
mobos to ordinary retailers ...

that is old story.
but SM don't sell to ordinary men, they sell to retailer/distributors, and distributor still sell to me.
Unfortunately, https://drunkencat.net/misc/SupermicroBIOS.html is not working.
Could I ask for the previous bios for the Supermicro X10SLM-F board - v3.2 and v3.3?
I really need these bios because nothing works with UEFI after changing to v3.4.
Thank you very much in advance and best regards!

Apache server hung for some reason. All fixed.
I don't know if you're interested, but I found an Item ID that's not listed in either of the tracking DBs:
I'm trying to fix an issue where onboard LAN1 and LAN2 disappeared after BIOS and IPMI updates, and found this while searching. Thanks to everyone who puts in the effort to keep the archives updated!

it is there but not listed because of duplicates. BMC Firmware is not unique to a motherboard, e.g. all with AST2500 share same.
I figured someone would put me in my place - LOL
But at least I learned something, and that's always a good thing.. thanks for filling me in! My brain is frazzled from working on this crazy thing......
