https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D260735 --- Comment #8 from Stanislav <stanislso@yandex.com> --- > Of course it may not be possible to determine that the memstick has boote= d to the installer (without video). Actually, there is a way: After the boot wait for a few minutes, then press <Tab>, <Tab>, <Enter> This will launch "Live CD". Type=20 root <Enter> to drop into the command prompt. This can be done blindly. Then try to enter the command reboot <Enter> If the host reboots, then the system was operational. I just tried this with success in a VM and then attempted to repeat it on t= he hardware using the latest memstick FreeBSD-13.0-STABLE-amd64-20211223-b30e760ce73-248689-memstick.img First of all, there is still no video output with the screen connected to an HDMI or Display Port past the "EFI framebuffer information". Second, the blind test described above did not give any result - the machine did not reboot. It does, however, respond to <Ctrl-Alt-Del>. An interesting aside, if I connect a really old 1024x768 VGA LCD monitor to= the VGA port and boot into the already-installed system, then after a while the mouse pointer appears on the screen, and then, after another minute a legib= le text login prompt appears as well. However, nothing, not even the boot opti= on screen or the POST screen are shown on the VGA display prior to that point. On the other hand, a newer display connected to the HDMI or Display Port wi= ll show both POST and the FreeBSD Boot options, but then nothing past EFI framebuffer information. So this is indicative of problems with video mode switching and the detection of display capabilities/resolutions. And booting into memstick using that old VGA LCD monitor did not produce any output to the screen at any point, however long I waited. --=20 You are receiving this mail because: You are the assignee for the bug.=
