Additional dual boot issues

[Andrew Falanga]

Ok, I was following my post in usenet (didn't know that messages posted 
here were propogated there, cool).  Someone responded to another chap 
who was having a similar problem as mine that the issue was probably 
that they hadn't loaded the FreeBSD bootloader on to the second drive.  
So, I did this:

# as root
dd if=/dev/ad0 of=mbr.ad0 bs=512 count=1
boot0cfg -B ad0

In my system, the IDE drive (with windows) is ad0 and the SATA drive 
with FreeBSD is ad4.

Now, when I'm presented with

F1 - FreeBSD
F5 - Drive1

I press F5 and am presented with
F1 - DOS
F5 - Drive0

This differs in that when I was presented with F5 on the first menu I'd 
press it and FreeBSD would boot.  Now, it appears to try to boot Windows 
but all that happens is I get a blank screen for a few seconds then the 
machine does a soft reboot and I'm back to the bootloader prompts after 
the BIOS does its thing.  What could be the issue now?

P.S. What does 'ad' mean in ad0, ad1 ... adN?  Also, remember that I'm 
not a member of this list.  Please respond to me directly when you 
respond to the list as well.  Someone who responded last time mentioned 
a gmail account, or something, if that is some sort of "work-around" for 
folks like me with limited space for e-mail, I'd like to know more.
