Compatibility with uefi bios
When I installed this card with an ASUS motherboard, I got a message when the PC started up indicating a secure boot violation.
However the card still works despite this message.
If you don't want to see it any more, you need to set the secure boot to non-uefi mode.
And after emailing the manufacturer, he gave me the procedure for updating the card driver, as it was impossible to find it on the internet and have it recognised as uefi.
Here's how to do it:
The lack of driver support is not the cause of the problem.
The 90431 driver is the default driver for the SATA AHCI controller, available in all versions of Windows 11.
In a compatible system environment, this default driver is installed automatically if SATA AHCI mode is enabled in the system BIOS.
