Default Display Openbsd boot with an old monitor

Hello,
I've just changed the motherboard of my Openbsd computer and I cannot see the boot sequence anymore.
I use an old monitor and the frequency seem too high.
Is there a way to force openbsd to use 800x800 during the boot sequence ?
Something with config -ef /bsd
Thank you

To my knowledge -- which is of course incomplete -- the vga(4) driver provides a wscons(4) abstraction interface for VGA-compatible hardware, while the pcdisplay(4) driver provides an interface to even older hardware, such as CGA or EGA. There are no "knobs" to my knowledge to address display devices attached to these video cards. What settings are there for display are for logical text screen sizes (80x24, 80x50...) and text fonts, and these will not address your apparent issue.

Perhaps there's a BIOS knob for your video card?

I've spent a lot of time trying to change things in my BIOS. Actually the BIOS is UEFI.
The graphic card is on the motherboard itself.

I tried to put these lines in /etc/rc.local but no success, I was prompted errors
#wsfontload -h 8 -e ibm /usr/share/misc/pcvtfonts/vt220l.808
#wsconscfg -dF 5
#wsconscfg -t 80x50 5

I really regret that I have bought this asus motherboard it caused me many problems

You might experiment with -current and EFI booting. it uses a framebuffer, rather than vga().

EFI boot is still in development, and is a work in progress. There's a howto from September here.

@mikygee, Would you mind posting the Asus model and the dmesg? If it is new enough to have UEFI, it is likely that it likely that the onboard video driver is intel or ati. inteldrm was recently updated in -current and some video drivers need firmware which has to be installed.

It's a good thought, shep, though I think drm(4) is not used by wscons -- its an X dependency.
