A corrupted MBR could do that. Try setting the HD to "NONE" in the
CMOS settings screen. If that lets it boot from the NetBSD CD, the
disk should still show up in the boot messages (as "wd0", if it's the
only one), because the NetBSD kernel doesn't care about the CMOS
settings. Now, "exit" from the NetBSD sysinstall; try "fdisk -i wd0";
"shutdown -r now", then add the disk back in the CMOS. If that doesn't
fix it, there are ways to really zero out the corrupted boot sectors,
but you'll risk losing data on the disk, so try that "fdisk -i" first.
