I just tried your latest code, and I'm attaching the logs with and without
PS2 support. I get an identical blue screen with both of them. There must
be something else that's stopping the boot.

1.186 bochs bios and adlo with patches that I posted to the list.

I was truncating the logs because I have a very verbose boot and it didn't
look relevant.
I saw your post about F7, and since it is silent I couldn't tell if it
worked. I still saw ACPI-related drivers being loaded.
Have you tried this on Bochs? When I was doing this before, Bochs failed in
a similar way to the hardware.
Thanks,
