Unfortunately there are other BIOS vendors, and we need a solution that works across the board and doesn't trigger false positives. (Most BIOS's don't set the enhanced keyboard bit for USB keyboards, and some don't set it for PS/2 keyboards either, hence turning off -P.) >> What dance? Works great for me.

Not all of those machines have TGA's, and you could be testing out the TGA driver. However, there is no song and dance, you set the console to serial for a TGA machine and it all works and fine. Not exactly a song and dance. :) > -- Terry -- John Baldwin <jhb@FreeBSD.org> -- http://www.FreeBSD.org/~jhb/ PGP Key: http://www.baldwin.cx/~john/pgpkey.asc "Power Users Use the Power to Serve!" - http://www.FreeBSD.org/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
