Is it possible to boot OpenBSD on a device which only has one video mode available through the BIOS?
At present, we boot in text mode via vga(4) and wscons(4). If we have a machine compatible with inteldrm(4), it attaches, and the dmesg output is then set to the highest resolution. Is it possible to boot with no dmesg output during the VGA text mode, but then once we attach to inteldrm(4), as if by magic, we get the dmesg output and can login. At present, with only one video mode on an inteldrm(4) compatible machine, the kernel boots, and then hangs / freezes. Basically, no dmesg output. Just sits there... Is it possible to say, okay, we have a resolution that's not compatible for VGA console text mode, but if we can attach to inteldrm(4) successfully, we can continue with booting? Or is it a case of a bad BIOS design in the first place, and it would be a case of making bad coding practice following someone else's bad coding practice, which is a mess. The machine in question is a Google Chromebook Pixel 2, which only has one video resolution available of 1280 x 850 x 16 in the BIOS. It has a Broadwell i7 processor. vbeinfo command in Grub2 lists just one value of 1280 x 850 x 16. Edward.
