No. Windows has destroyed the system; it is necessary to reboot in order to restore it before FreeBSD can operate correctly. You should complain to Microsoft about this; it's their software that's trashed the vectors. > Many people who run multiple OS's rely on fbsdboot to recover > when their boot block has been trashed. Boot from a floppy. > Can this memory check be changed to detect whether the vectors > have been changed ?? No; it's effectively impossible to do, and makes the functionality useless in the first place. -- \\ 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
