installer fails to boot on x86_64 board

I have a mini-pc with a VIA Eden X2 U4200 1 GHz CPU, 2GB RAM, and ASMedia ASM1061 AHCI. I am trying to install FreeBSD 14.1R-AMD64 on it, but the installer USB fails to get to the installer menu. Things start fine, but boot always hangs at the point where HDA and PCM are shown. As I do not get to the point where I could have a shell, I cannot provide dmesg or pciconf output. I did try fiddling with the boot option, trying safe-mode, ACPI on/off, and verbose mode.
Here is the last screenful of output I can see:
Code:

And that is where it always freezes.

I tried booting other systems from USB, these all worked fine.
NetBSD 9.3 x86_64 installer, could get to a shell.
OpenBSD 7.6 amd64 installer, could get to a shell.
Haiku R1beta4, boots to GUI, sound/disk/graphics works well.
GParted Live debian 6.10.11-amd64, boots to GUI and works fine.
Fedora Server 39 x86_64, boots to the graphics installer menu, did not test further.
Windows 10 22H2 64-bit, successfully installed from USB, works fine.

So it seems that the hardware SHOULD work with FreeBSD-amd64 and FreeBSD-i386, but apparently the installer fails to boot up a functioning system.
I tried 13.x too, and i386 too. All FreeBSD installers hang exactly as shown above.
This mini-pc is pre-EFI, boots only in BIOS mode.

I do not have experience with getting the installer completing to boot on a hardware that it does not seem to like.
I can get hardware details if needed from Win10 device manager or OpenBSD dmesg and pciconf.

Any advice, suggestion, pointer on what to try or read is more than welcome.
