To xpetrl <xpetrl () aol ! com>: But then I would need to have every computer's serial port connected the whole time, right? As far as I know serial ports are not hot-swappable.
To: Stuart Henderson <stu () spacehopper ! org> The used graphics card has an Nvidia chipset, GT710, not a Radeon. Since there is no specific drivers for this at OpenBSD, it uses the generic vga driver. But I get your point. About dmesg, I read the ddb(4) manual and I understand that typing "boot dump", powering off after reboot and turning on with the card reinstalled would make the previous dmesg somewhere accesible, but I was trying to avoid this. I will not have physical access to the computer until monday and even then I will need to take the card from another computer. To Kenneth Gober <kgober () gmail ! com>: Isn't "APU" an AMD trademark for their processors with GPU integrated? If I choose com0 as the default console but don't connect anything to it (not even a COM port card to the motherboard's COM pins) would it still fail because no console is detected? Could I choose an ssh console instead? If I remember correctly, ssh consoles also have their /dev/tty"something" device. Thank you all for your answers
