I don't know anything about graphics, other than they look pretty. :-) Note that this functionality is intended only for kernel consumption, not user-space applications like doscmd. In particular, when making a vm86() call, logically kernel stays at ring 0, meaning that no context switches are allowed. I'm working on a general user-space vm86() function as well. -- Jonathan To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
