Question SATA DVDRW not detected with new x870 motherboard

[adsoyo]

Recently finished upgrading my system with a MSI MAG x870 Tomahawk Wifi + 9800X3D + 32GB DDR6000. The only issue I'm having is my DVD drive isn't recognized in the BIOS. It was working perfectly on the previous MSI B550-A PRO motherboard. The DVD player is an Asus DRW-24F1ST/BLK/B/GEN that I bought in 2018.

I verified it's getting power, tried 2 different SATA cables, tried 3 different SATA ports. I'm running the latest BIOS from MSI's website which is 7E51v1A1A posted on November 21st. They have 3 different BIOS versions on their site, all beta.

Does the drive show up in BIOS? Speaking of BIOS, did you clear the CMOS after verifying you're on the latest BIOS version[7E51v1A1A(Beta version)]?

Manual for your motherboard says the SATA ports are driven by an ASM1064. Did you install the OS in offline mode for your new platform? If not, you might want to see if manually reinstalling your chipset driver in an elevated command, i.e, Right click installer>Run as Administrator.

A couple of thoughts:

1). Your DVD Writer might require ATAPI support enabled in the BIOS (if available).

The drive does not show up in BIOS. The BIOS was factory reset after updating to the latest version.

I did not reinstall the OS, to my astonishment, it fired right up. I anticipated having to reinstall Windows so I disabled the wifi in BIOS and installed the motherboard drivers offline.

I don't recall seeing an option concerning ATAPI in the BIOS, I'm wondering if it hasn't been added yet since the motherboard is still in beta apparently.

Try legacy mode in the BIOS (CSM enabled and secure boot off).

If you migrated platforms(swapped motherboard) then you're going to have to reinstall the OS, that's what is necessary now, not taking detours via troubleshooting.

Ok thanks for the tip.

If the drive isn't showing up in BIOS how is reinstalling the OS going to help?

If you cannot see the DVD drive in the BIOS, I very much doubt reinstalling Windows will make any difference. A fresh install will clear junk out of the Registry, but you can carry on experimenting as you are.

ATAPI is what I term a "legacy" protocol more commonly associated with the old IDE parallel interface, which used 40/80-way ribbon cables to connect hard disks and CDROM drives, etc. ATAPI also applies to SATA, but might not be implemented in a modern BIOS unless you invoke "Legacy CSM", as @dcvikes suggested.

Check your BIOS to see if there's a UEFI + CSM option. You'll probably be booting Windows using UEFI, so you need to retain this option, but without older CSM enabled, the DVD might remain invisible to the BIOS. I sometimes enable CSM to find ROMs on older SAS HBA controllers and SFP+ 10Gbe NICs.

The copy of the B550-A PRO manual I downloaded from MSI is absolutely useless regarding BIOS settings, so you'll have to experiment. Look in the Boot section for UEFI/CSM. If you find it, try various combinations, e.g.:-
1). UEFI First, CSM Second
2). CSM First, UEFI Second

Looks like the motherboard doesn't have a UEFI+CSM option, it's one or the other. I haven't tried turning on CSM mode yet, I'll do that soon. Is there such a thing as a UEFI DVD player? I did a quick check on Newegg and all the drives they offer have been on the market for years. There are 2 that were released in 2019 otherwise they all say 2014-2016.

I've not heard of such a device. I just buy optical drives, plug them in and the BIOS recognises them. My most recent purchase earlier this year was a Blu-ray writer, which works fine on my X670 chipset.

If you can't get the drive working with the on-board SATA ports, try an inexpensive PCIe card if you have a spare slot. At under $10, it's not a huge gamble.

I have had a similar problem w/a USB DVD-RW, Once I changed over to UEFI mode (i.e. from CSM mode), it disappeared from the BIOS (but appears as a USB device) but is fully functional once Windows 10 is loaded. I can't boot from it unless I'm in CSM mode. This is on an old z390 motherboard though.

Thanks for recommending that card, didn't even cross my mind!

A friend has my old B550 + 5800x and hasn't installed it yet. I'm going to ask him to check the BIOS and let me know if it's in UEFI or UEFI + CSM mode.

I messaged MSI tech support about this yesterday and they responded today. They said unplug the computer and hold the power button for 1 minute to "power cycle the board". I did that and it didn't work. I'll keep this thread updated.

Aren't UEFI and CSM mutually exclusive? The only way I could get resizable BAR working was to disable CSM.

 

[adsoyo]

I did some work on my other computer with a x570 motherboard so I figured I'd plug the DVD drive into it just to be extra sure the drive didn't suddenly fail. The BIOS detected it no problem and it's set to UEFI mode. At this point we know the drive works, we know the cables work, we know the SATA ports on the x870 motherboard all work. It HAS to be a BIOS malfunction at this point right? I just wish I could find other people around the internet with my issue. No new email from MSI in the last 2 days.

A quick skim through this article appears to confirm your suspicion, especially if your BIOS does not allow UEFI + some Legacy options at the same time. My motherboard chipsets are older and I'm still running Windows 10 with Secure Boot and TPM disabled, but with UEFI enabled.
https://www.tech2geek.net/csm-vs-uefi-whats-the-difference/

If you're running Windows 11 and you installed the OS with Secure Boot and TPM enabled, the "user-unfriendly" BIOS in your 870E seems to have locked you out of your 2018 DVD drive.

Unless you're prepared to try a test install of Windows with the BIOS set to CSM and forgo the "benefits" of Secure Boot/TPM, you might have to buy a USB DVD drive. It's vaguely possible a modern (2024) internal DVD drive might be detected in your UEFI BIOS, but it's a long shot.

My USB DVD-RW doesn't show up as a bootable option when the BIOS is set to UEFI (but it shows up as a USB device when you examine the USB tab), but it works fine once Windows 10 boots.

The x570 computer that it DOES work in is set to UEFI mode with TPM and secure boot enabled same as the x870 computer it doesn't work in. I'm still convinced this is a motherboard software issue. I'm still planning to set the BIOS to CSM just out of curiosity but at the end of the day it needs to work in UEFI mode with TPM enabled. Still waiting for a new response from MSI.
