Dell Pro Slim

I am using Fog 1.5.9 and a bzImage files with kernel 6.1.32 as this what we needed for our HP Z G9 workstations. I later changed it the FOS of 2025-07-15

We are testing a new computer, a DellProSlim computer, model qcs1250, which are new demo model. using an Intel Rapid Management Driver.

These have 3 options in the UFEI/BIOS under storage for Windows to boot from
RAID Mode
AHCI/NVMe Mode
Disabled.

Dell Had the “RAID Mode” as default and AHCI/NVMe will not let us boot the drive. The RAID mode is the default and is the mode that Windows 11 boots from.

We attempted to even just register the computer in fog, but the FOS would halt and not do anything. I updated the bz image from release 2025-07-15 and it would at least get to a point where it had an error of not detecting the NVMe drive.

I did a work around to switch it to “AHCI/NVMe mode” and it worked and I could register and capture the image and the FOS kernel would detect it. I had to swithc it back to “RAID Mode” to boot Windows 11 again for a single drive.

I can try the latest FOS kernel of 31 July, but I have a feeling this is a long standing issue with the linux kernel used.

Is there a BZ image we can try that has this Intel RAID stuff in it to try? Otherwise I can get this set up with Windows 11 from scratch or some registry hacks so we can leave it on AHCI mode.

If anyone else has these gen of Dell computers would be good to know.

@mrowand We’ve been trying to figure out exactly what to do using the MB Raid methods to detect a disk.

While there are seemingly some configs that will take motherboard RAID in a format that is detectable to kernels, there’s not one option I’ve been able to find (as of yet) that will do this natively.

Unfortunately, the solution is your secondary option (at this point) -> Set SATA mode to AHCI and either reinstall Windows 11 on the AHCI mode, or perform your Registry hacks.

Believe me, I’d much prefer to have the kernels just detect the MB raid modes.
