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
