Linux and bootsectors

Under Linux, how do I get my bootsector to a FAT12 floppy. I know how to do it with PartCopy under Windows. My guess is that I have to use DD under Linux.

Thanks in advance,
K.J.

I think it was "dd in=YourBootsector out=/dev/fd0", but I'm not sure!!!

Close, dude :)

I'm pretty sure it's
dd if=./bootSect of=/dev/fd0

if = input file
of = output file

However, you're probably gonna want to put a size
argument in there as well... it _might_ go
beyond your 512 bytes, unless you specifically
tell it not to.

Also, note that the size argument (I think it's
just size=x, but check the man page to be sure)
is based on block size, which, for a floppy device,
would no doubt be 512 bytes, so set size to 1,
not 512.

Here's what I found(haven't had time to test it yet though):

dd if=my_boot skip=0 count=3 of=/dev/fd0
dd if=my_boot skip=36 count=476 of=/dev/fd0 seek=36
