Does a Studio 1558 with BIOS A12 support UEFI Boot?

Believe it or not, I have Windows 10 running on this now (works well).  I've figured out that as of today, if the processor supports SSE4.2 (this one does!) AND UEFI booting, then I should be able to run Windows 11 on it (by using the TPM and Secure-Boot Bypass, hacks).  So far, I haven't figured out how to get a UEFI disk to install and boot.

Download Windows 11 ISO from Microsoft, download RUFUS and create an installer USB.  Besides the bypass selection, select the boot mode that match with your system BIOS settings, UEFI or Legacy.  The installer should boot with your system.
