Many of these are actually supported "properly" now with Luigi's code.

Unfortunately, this isn't the case. A DOS-mode driver doesn't adjust the BIOS memory tables (for obvious reasons), and most DOS-mode drivers are going to want to have resources vectored to them that are simply not available. It was a nice idea when we were talking about it before, but basically by the time you've reverse-engineered a driver enough to provide it with an adequate emulation environment, you might as well rewrite it properly. -- \\ Sometimes you're ahead, \\ Mike Smith \\ sometimes you're behind. \\ mike@smith.net.au \\ The race is long, and in the \\ msmith@freebsd.org \\ end it's only with yourself. \\ msmith@cdrom.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
