NanoBSD boot failure

[Sean Bruno]

I've run into a weird boot failure with a new Intel 
motherboard(http://www.intel.com/products/motherboard/D201GLY2/index.htm).

I have installed a Transcend 512MB IDE 
module(http://www.transcendusa.com/products/ModDetail.asp?ModNo=26&LangNo=0) 
as my boot device.

If I install a minimal FreeBSD install from CDROM, the machine boots 
just fine.

If I build a NanoBSD image and dd it onto the device, the system 
attempts to boot and just sits at a blank screen with a flashing 
cursor.  I never see the boot loader start or the kernel begin to load.  
The same image on several other motherboards works just fine and has 
been serving us well over the last year.

Any ideas where I should start looking?
