Hmm I have some old patches lying around for syscons, so that it can used both a mda & a vga simultaniously if both are present, priority could easily be changed.=20 If I remember right you can set the PC to boot into whichever you want by setting the BIOS to either monochrome og vga. Syscons could then take over the device that the BIOS used as default. As I see it there is no need to muck with the bootblocks.... > Would you be interested in looking at the patches and give me your opin= ion ? > Do you think there would be any interest in including this in -current = ? (or > any other version for that matter:). Lets have a look at it, I'm mostly for the "dual video card" support, tha= n for some specific hacks to the bootblocks & drivers... I dont think we need "Yet another kernel option", we have plenty of that allready. -=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D-= =3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D= -=3D- S=F8ren Schmidt (sos@FreeBSD.org) FreeBSD Cor= e Team Even more code to hack -- will it ever end ..
