Check it the system is capable of BIOS Legacy (CSM) mode booting instead of UEFI. If so, try using old console driver "syscons" instead of default vt: escape to loader prompt and do: set kern.vty=sc boot -v Or, add to /boot/loader.conf: kern.vty=sc If UEFI is only option, try using default vt driver but with text mode instead of framebuffer: hw.vga.textmode=1 Some of ACPI BIOS'es have bugs in ACPI Tables and there is workaround for the problem: hw.vga.acpi_ignore_no_vga=1
