yup ... i knew i shoulda looked it up first ... bs=446 is right
and if one is lucky, one can restore the partition
table at exactly the same cylinders and everything
"should" still work too
#
# another piece of important info needed to "restore" your system
# one day ... when the partition table gets messed up
#
fdisk -l /dev/hda > /floppy/hda.fdisk.info.txt
and still another option for overwriting the mbr,
#
# if you have a previously good boot file that you wanna restore
#
dd if=/boot/boot.0300 of=/dev/hda bs=446 count=1
