It is not possible, to upload a file correct to this server any more.
Do you have another place, where I can upload it

And there are more files needed for CSM (legacy boot),
for example

Here is the documentation of CSM from Intel.
I wonder, why also an csmcore was build for the Arrow Lake Bios.
May be, that UBU does not correct identify everything about CSM.
For example, there is no GUIDE number in it.
I also try the MMtool. No csmcore is listened in both Bios

Yepp, I get via UBU from the 12900k Bios csmcore.
It starts via Winhex with CSM.
Now I just look, if this is already in my file CsmDxe
Dietmar
EDIT: Also in the 245k Bios a csmcore was build via UBU. But this one starts with CSM..MZ no VGA video there.

I just check: Csmcore has Guide A062CF1F-8473-4AA3-8793-600BC4FFE9A8
This is the same Guide as for the Bios from the 12900ks CsmDxe

I notice, that in the Arrow Lake Bios this files are also missed:

I heard about this tool UBU but never used and so I also dont know, how to handle it.
Do you have an UBU version for me, that works for the 12900k and also for Arrow Lake (245k) here,

How can I extract this csmcore? I do not see it with UEFITool.
And I remember another part in the NVRAM:
There has been a switch from Windows 10 ==> Other OS

The Bios is NOT write protected, take a look at this
AmiSetupWriter.efi 0xd25 0x2
NVRAM variable "Setup" read, data size 0x1270, attributes 0x7.
Current Setup[0xD25] is 0x0
NVRAM variable "Setup" written.
Updated Setup[0xD25] is 0x2
Dietmar
EDIT: I just check with RU.efi, that indeed in UEFI name Setup now at adress 0xD25 is written 02.
But still no harddisk with MBR is recogniced.
Any idea, at which place I have to look for to enable CSM?
The dump of all adresses with names via AmiSetupWriter.efi -d > all.txt
does not work.
EDIT2: I also wrote for to enable CSM
AmiSetupWriter 0xCBE 0x1
The value at 0xCBE changed from 00 => 01
but still CSM is not working.
EDIT3: May be, that a compare of the Bios, from where this 3 csm files are taken, can help to set all (in Bios unseen) variables in the Bios above, its NVRAM for CSM boot, correct.
EDIT4: After checking about the risk, low, I did the following:
I replace via UEFITool the whole Setup Guide 899407D7-99FE-43D8-9A21-79EC328CAC21
in the Bios from the 245k with the one from the board with 12900ks cpu.
Before, I make a direct copy of the 12900ks Bios, fo to keep the settings for CSM.
Q-Flash allows this crazy Bios implantat.
But after reboot, I see only the screen, where I can choose between Delete (Bios Setup) or F12 (Boot menu).
No other reaction. I also clear CMOS, does not help. Compi is frozen at this screen.
But maybe this idea is not so bad, just you have to know, which parts of this Setup Guide have to be copied and which not.
Just now I flash the original Bios f6c back to the 245k board, compi is alive;))..

I succeed to flash my modded Bios via Q-Flash.
For this I just renamed my modded Bios to
GIGABYTE.BIN
and flash it with only Power Supply on, pressing the Q-Flash button.
Lasts about 3 min.
Oh,..soso much worry, but compi starts again ;)).
Of course no switch for CSM in Boot menu, but I think I can handle this like on the N100, if there is any chance

Hi Gelip,
here is my first try.
The Bios from Gigabyte for both boards are VERY similar.
I put those 3 CSM files via UefiTool exact at those places where they where before in Bios F11.
Please take a look at the modded Bios, which Bytes needs to be set for to enable CSM.
Also I think, that Secure Boot has to be disabled.
Thanks a lot

Bios for the gigabyte b860 ds3h original and mod for CSM
0 -
Hi,
I noticed, that on all boards for the Arrow Lake cpu from Intel, there is no CSM for legacy boot of XP, Win7 etc. anymore in Bios.
About Quibble I heard, that it cant boot UEFI class 3 boards, which means no CSM at all.
So, only way is to do it by myself.
May be, that there is already a generic CSM dxe driver on the market, as the nvme.dxe from the Bios of the Samsung 850 for nvme boot.
I have a board gigabyte b760 ds3h ddr4. This has CSM. I use Bios F11 for it.
And I have a board for the Arrow Lake cpus gigabyte b860 ds3h, no CSM at all. I use Bios f6c for it.
My first try is just to integrate those 3 CSM files from the F11 Bios into the f6c Bios.
CsmDxe.ffs
CsmVideo.ffs
CsmBlockIo.ffs
As I learned the hard way from the Asrock N100DC-ITX board, those drivers have to be enabled in Bios also.
This may be a much too naive try, because I heard, that CSM is deeply integrated in Setup in Bios.
Very small information you get about the definition of the integration of CSM in Bios. It is an UEFI dxe driver.
@Mov AX, 0xDEAD told me some times ago, that all the documents for CSM are Open Source,
but I have no idea, where to look for

Yepp,
I just check:
For example, the B850 EAGLE WIFI6E board for AMD has CSMcore in its BIos

Hi,
no legacy CSM mode on any Bios version until now for the GIGABYTE B860 DS3H.
I also check a lot of other boards for the Arrow Lake cpu. No CSM everywhere.
This will be a really hard job, to implement an working CSMcore.dxe into this Bios.
I will make a try in my next holidays beginning at 5 of April
It comes with Bios version 3, now I have 6c.

Hi,
ufile.io does not work for me just now.
Do you have a place, where I can upload

Because I just have some time and money,
I bought just now for the fun test with XP SP3
Prozessor Intel Core Ultra 5 245K (I compare a lot and this is the only one I like in Arrow Lake 3nm)
Motherboard GIGABYTE B860 DS3H (with PS/2 and Serial COM port for ultimative tests)
Memory Corsair Vengeance RGB grau DIMM Kit 32GB, DDR5-6000, CL30-36-36-76 (I do not think, that any other memory is faster all together)
CMH32GX5M2B6000Z30K
Be Quiet Dark Rock Pro 5 (I have already. This is the best AIR cooler ever, now with more space between the cooler and ram).
Soon fun starts
Dietmar
EDIT: Does anybody know, if there is a motherboard for the Arrow Lake cpu, that supports CSM, legacy boot?

Hi,
during install of my german xp.iso and update it via Legacy Update,
I get some strange crashes on the Asrock z690 Extreme board with 14900k cpu.
This NEVER happens with the 12900k cpu on the same board

Hi,
I put the 14900k into the Asrock z690 Extreme 1700 socket board.
Before first start, I update this board to the very last version of its Bios 20.01, which contains all the changes from Intel, for example in Microcode for the 14900k.
This board Asrock z690 Extreme is the most stable board from all boards, that I ever tested in last 24 years.
Now I run prime95 on it.
It throttles also, but only from 5700 MHZ ==> 4900 MHZ maximal.
Via this, the temperature with Dark Rock Pro 5 reaches 97 degrees on the E-cores, 92 degrees on the P-cores.
prime95 runs now for 20min, no(!) crash.
So, it looks that Intel did their most possible repair for this 14900k cpu.
On the Asrock z690 Extreme board the 14900k seems to be stable and shows only little throttle under XP SP3

I make a direkt compare with the Intel 12900k.
In prime95, the maximal power consumption is 242 Watt. No crash.
But the maximal throttle in prime95 is only from 4900 MHZ ==> 4800 MHZ.
And the max allowed temperature for this cpu is 115 degrees,
for the 14900k only 100 degrees.
Result: The 12900k is the much more stable cpu
Dietmar
EDIT: Out of the blue I have just a crash of one E-core, temperature about 70 degrees from the 14900k cpu, brrr..

Hi,
just now I update to the very last version F11 for the Bios for this Gigabyte board.
First impression: Cinebench shows 5% less points.
The throttle is now not as hard as before.
The power seems to be restricted to 250 Watt.
The whole temperature difference through all the cores goes now down from 21 degrees to 9 degrees.
The hottest core (E-core) shows now 91 degrees in prime95. Before, with the Bios F8, it was 97 degrees.
Prime95 is now running for 10 min (with AVX). No crash but throtteling as heavy as possible.
EDIT: Now prime95 runs without any crash for 38min. So it passes the critical 19min of prime95.
I never saw a compi, who crashes in prime95, after it survives the first 19min.
In prime95 the cpu never runs with its 5700MHZ, maximal with 5300MHZ, this means throttle even before start.
This means 7.5% less computer power, brrr..
So, the power consumption changes from 250 Watt to 65 Watt in a second and then back after few seconds, because the frequenzy for the the cores are set to half, exact as with the old Bios.
This behavior I have NEVER seen on a 12900k.
Dietmar
EDIT: When you take a look at
https://cpu.userbenchmark.com/Compare/Intel-Core-i9-14900K-vs-Intel-Core-i9-12900KS/4151vsm1821519
you see, that after the new Bios gives 5-7.5% less computer power for the 14900k,
now it is nearly equal to the 12900KS. BUT the 12900KS does not show heavy throttel.

Yepp, even the E-cores runs much hotter (97 degrees) than the P-cores,
it was a P-core that crashed at only 75 degrees.
So, Intel has a really BIG problem with their new chips
