Dell has a driver update page for the ECS1250 at <https://www.dell.com/support/product-details/en-us/product/dell-ecs1250-slim-desktop/drivers>. I don't see anything about Phison controllers. Is it a non-OEM addon? The machine received a BIOS/UEFI update last week, dated 13 Apr 2026. You might try the update before going down a rabbit hole. The BIOS/UEFI is just another buggy program that needs updating on occasion. Jeff
