I merged approproate fixes from DragonflyBSD in commit below. Success/failure reports from people affected are appreciated. kann 2004-08-05 06:00:05 UTC FreeBSD src repository Modified files: sys/boot/i386/boot2 boot1.S sys/boot/i386/btx/lib btxcsu.s Log: Move boot2 BSS zeroing into btx startup code out of boot1. boot1 does not have clear idea on boot2 BSS size and leaves portion of it not zeroed out. btxcsu.s is in much better position for this job.
