I found my solution, wanted to post it here in case someone else 
encounters it.  I checked the FAQ first to make sure I didn't do another 
"duh" post again, LOL.

The image was made using an old NT 4.0 SP0 workstation using 
phydiskwrite.exe.  I thought maybe being an ancient build of NT 4.0 was 
the problem.  It actually wrote the image just fine, so that is ruled 
out.  The PC I was trying to boot with the IDE drive has a few BIOS 
settings for the drive.  Mainly the LBA disk mode needed to be turned 
off.  The drive disk geometry mode also had to be set to "Standard 
CHS".  Once this was set, the drive would boot m0n0wall properly with no 
issues.  This might only be an issue with really old computers like the 
one I was using.  I haven't had a more modern system to try this on yet, 
so this may not be an issue with newer PCs that you load m0n0wall onto.
