ASRock z-170 k4/d3 sata controller not being initialized correctly when enable "above 4g mmio bios assignment"

[jnyk]

Motherboard: ASRock z-170 k4/d3
GPU: 6700xt
CPU: 8700k
I can't open the "above 4g decoding" or "above 4g mmio bios assignment"

when I turn this to enable ,it can't work, can't into windows system ，because bios can not find any sata drives

then when i try to use modGRUBShell.efi
setup_var 0x3 0x0
reboot
setup_var 0x3 0x1
but there is nothing happend

It makes me very depressed. Can you give me some suggestions

I believe that it's same issue #35

@jnyk do you have ch341a or another programmer? If it's dsdt issue, I can reinsert dsdt from another ASRock motherboard, that works as intended

yes I have met similar situation with him,can not extract DTST from AmiBoardInfo2.I have bought one ch341a ,meybe it will cost two days from online store to me

[xCuri0]

DSDT is in DsdtAsl, not AmiBoardInfo2 @jnyk

[dormancygrace]

@jnyk here you could try this bios, dsdt patched, uefipatched. Just enable Above 4G like usual, the one that made windows hang/freeze. z17gkd37mod.zip

Do you use this mb? Or just made modifications? What you changed in dsdt?

i dont use this mb but i've done several dsdt fix on asrock boards (yes they're just pAWJPASJd;JDp[ to fix sometimes)
what did i change? well mainly the qwordfield under the first dwordfield, then also correcting the rest of dsdt errors (its a long list lol)

and no, i dont slap other board DSDT on this bios

Is there coffee lake mod? Because @jnyk use i7-8700

But there is already qwordfield in dsdt in this board. I'm 90% sure that there is no need to patch uefi not dsdt. I will make bios without patching

this one is modded non coffee lake bios:

[dormancygrace]

heres the one with coffee lake mod @jnyk z17gkd37_2.zip

Please, make one without any patches.

He could test it and if it's working it could be the DSDT faulty? he's the one testing it. if anything went good then DSDT was the one causing it, if its not, then it wasnt it, simple. Even if everything seems to be in place, sometimes it's just sketchy XD

As I mentioned, I've compared dsdt from similar ASRock mb - they are +/- same (identical in qwordfield and m1.. parts)

let him reply first okay? he's the one testing

[jnyk]

thanks @Koekieezz .I'm working now ， may not be able to reply to a message promptly.
I will try this bios when i get home.

[jnyk]

By the way ,I try to patched UEFI to my bios last night.After I flashed the ROM whitch I patched into mainboard, windows can be used as usually, but when i insert the usb disk ， it could not start windows system, utill i remove the usb disk

[dormancygrace]

@Koekieezz is it secret, what you changed? i'm asking because stock dsdt and from your file - completely same

[Koekieezz]

@Koekieezz is it secret, what you changed? i'm asking because stock dsdt and from your file - completely same

no.. both files have 0x7FFFFFFFFF on 1st qwordfield, and for the rbarcfl one have acpi fix on dsdt then apply the dsdt patch

I`ve attached screenshot of files compare. only difference is disassembling by iasl

[jnyk]

@Koekieezz I just instant flash the bios ,
when i open above 4g mmio bios assignment, it can not find any disk drive as before.
i use asrock's tool to flashed bios,may be use ch431a it will be ok

Ch341a you need to use in case of major failure

[dormancygrace]

@jnyk
z17gkd37.zip

try this one

[jnyk]

i flash this bios with ch341a ,but It's still the same as before

[jnyk]

@dormancygrace ok I‘ll try it

[Koekieezz]

i have 2 bioses attached 12h ago, they have different dsdt from normal ones, its this one: z17gkd37rbarcfl.zip, check em again

[jnyk]

@dormancygrace It's still the same as before . start my conputer can't find any disk drive except usb disk ,and can not inter into
neither windows system or winpe system

are you sure it's the correct bios? since i had some edits and deleted the first reply, the correct one have 2 files in 1 post. its this z17gkd37rbarcfl.zip one to use if you had the wrong one. try modgrub method to enable it and see if it's working.

this is similiar to this guy on winraid, he managed to enable it. Here is your above 4g:

So try to do setup_var or setup_var_3 0x385 0x0, reboot (type it and enter), then 0x385 0x1, reboot (type it and enter).

[jnyk]

@Koekieezz yes wo download this z17gkd37rbarcfl.zip one

i can not find disk drive untill setup_var 0x385 0

[jnyk]

your mean is i need try to setup_var 0x385 1 gagin?

[xCuri0]

@jnyk the wiki page says that even if it shows 0x1 it can still be disabled

you need to set it to 0x0, reboot and set to 0x1 before rebooting again

i had to do this with setup_var 0x3 on my b75 motherboard

[jnyk]

yes you are right but i had did all these steps ,and it was no different

[psyborg55]

i've noticed, that after AMIBCP microcodes looks like same file, before amibcp
There 2 places in BIOS with 4gb decode:


Maybe, on this MB better to enable it with grub method?

I think @jnyk enabled only the second one. Maybe enabling both or only the first one will fix it ?

Maybe, but how? On other (working) ASRock z170 I've enabled only second one

Enable the first one with "setup_var_cv PCI_COMMON 0x3 0x1 0x1"

[jnyk]

should I use the "setup_var_cv PCI_COMMON 0x3 0x1 0x1" command?
OK I'll try it ,thank you for your help

[jnyk]

@psyborg55 I think this command can not work , mybe

[psyborg55]

It shows on screen it is working, set from 0x00 to 0x01.
If it remain 0x01 after power cycle then this is it.
Maybe offset is not 0x3, but 0x2 or some other, you have few settings there so just need to check them.
In laptop support issue i posted screenshot with almost identical pci subsystem menu

[Sortoftired]

i have an asrock z170 gaming k6 and experiencing the same problem.
here are my thoughts:
1.can we try update oprom of ahci controller?
2.there are settings of sata controller in bios



3.if this mb has a thirdparty sata controller,maybe we can connect drivers to sata ports on it.

[Sortoftired]

i reported this issue to Asrock Tech Support,and they replied in like 15 mins.they sent me a new bios 7.50A and told me "we have added Above 4G Decoding in it".i haven't tested it yet,but i think maybe contact your mb's manufacturer isn't a bad idea.
PS:maybe we can figure out how to mod all Asrock 100 series mb by comparing 7.50 with 7.50A and find out what they did.
Z170 GAMING K6(P7.50A).zip

[jnyk]

@Sortoftired thank you it's a nice idea, I'll try to connect Asrock Tech Support

[Sortoftired]

i'm sorry to tell u that after several mails between me and asrock guys they determined it was some bug in kernel codes,and since it's an 7 yrs old mb,they told me they have no bios update plan on this any time soon.
PS:i have done another test on my mb.my k6 mb has 2 thirdparty sata ports provided by ASMedia ASM1061 chip onboard,and with above 4g on and csm off,this 2 ports can function normally,unlike the 6 sata ports provided by z170 chipset.

[xCuri0]

@Sortoftired did they atleast mention the module with the problem ?

So that we can try swapping it ?

[xCuri0]

@Sortoftired Also can you tell device/vendor ID of SATA controller ? I figured out it's possible to make a patch to force it to be allocated in 32-bit space that will probably fix it

[Sortoftired]

@xCuri0 no they didn't.
and yes i can tell you device/vendor ID of sata controller once i get home.
to be clear it's the ASMedia ASM1061 sata controller you are talking about yes?

[xCuri0]

@Sortoftired I'm taking about the broken Intel SATA controller. I can add it to 64-bit BAR blacklist in PciBus module with a patch.

Also do your USB 3.0 ports work in BIOS with 4G decoding ? They don't work for me because of a similar issue where UEFI driver doesn't function properly with 64-bit BAR (although it works in OS here)

[Sortoftired]

@xCuri0 i haven't tested yet but i think it's the same situation with usb 3.0 ports.my mb has thirdparty usb chips ASMedia ASM1142,and work properly in BIOS with 4G decoding.but i haven't tested usb ports on intel z170 chipsets.

[Sortoftired]

@xCuri0 i have booted win10 from ASMedia ASM1061 sata controllers,it takes a lot more time than usual.and in device manager there are disks connected to broken sata ports,and disk manager says they haven't been initialized.
aida64,crystaldiskinfo,hwinfo64 all stuck at detecting sata devices
i tested the speed of sys ssd,the result looks fine,so i guess the extra long boot time wasn't ssd's fault.might be bugs in initializing controllers and detecting devices.

[xCuri0]

@Sortoftired Can you show a screenshot of Device Manager, View->Resources by type and expand memory scroll to bottom ?

And also Intel SATA Controller device IDs

[Sortoftired]

@xCuri0 i was just about to lol

[Sortoftired]

@xCuri0 now i'm going to reboot to normal state to check the device id

[Sortoftired]

[Sortoftired]

@xCuri0 would that be enough for now?cause i have to go to work at 2pm

[xCuri0]

@Sortoftired yeah it should be for the SATA issue

[xCuri0]

You can try this patch

# PciBus | Add Intel Q170/Q150/B150/H170/H110/Z170/CM236 Chipset SATA Controller to 64-bit blacklist (fix broken SATA)
3C1DE39F-D207-408A-AACC-731CFB7F1DD7 10 P:DE10D301FFFF00000B:868002A1FFFF00000B

I made it originally for Intel 7 Series USB 3.0 Controller but I just changed device id here for Intel Q170/Q150/B150/H170/H110/Z170/CM236 Chipset SATA Controller

[Sortoftired]

@xCuri0 ok,thanks

[Sortoftired]

still broken sata

device manager looks the same

[xCuri0]

Screenshot doesn't show Intel SATA Controller in 64-bit space, guess it's another issue then (unless the device is hidden for some reason)

[Sortoftired]

@xCuri0 maybe standard sata ahci controller is Intel SATA Controller？the name was because of the chipset driver installed

[xCuri0]

it's in 32-bit range, it should be fine if the cause of issue is 64-bit Intel SATA controller

[Vinjul1704]

I seem to be affected by this too on my ASRock Z170 K4/D3. ReBAR seems to be working fine (despite the DSDT range check suggesting otherwise?), but SATA drives don't show up.

Flash drives and even USB Sata adapters work fine and I can load up Linux Mint using those without issues, although it's obviously noticably slower. Windows doesn't boot like that, but I suppose it just doesn't like the adapter I'm using.

It's worth mentioning that I'm also using the coffee lake mod with an 8700k. The vars I had to set to 0x1 were 0x3 for 4G and 0x385 for MMIO.

I'll try to contact ASRock support and ask for a BIOS version with Above 4G support "properly" added/enabled in the BIOS settings, since that seems to have worked for someone else in here.

Is there anything that can be done to fix this issue though? I saw a patch further up in this thread, but that seems to just blacklist the controller entirely to avoid some other issues. Anything I can do or any information I can provide to help get this resolved?

Thanks!

[Vinjul1704]

Looks like the M.2 slot still works fine. I'll order a PCIe SATA card and see if that one works fine too. If it does, I guess I'll use that as a workaround for the time being.
