What is an 'enhanced' BIOS in Optiplex 740

[optiplex-er]

I really need Dell to help me out it seems but customer service over the phone is crap and on-line you have to register or something.
my dad's comany is off-loading older model Dell Optiplex's, I have been playing with like 3 different models.
this one is AMD and it's BIOS upon boot says it's 'enhanced'.
thanks for the two questions I asked today (another thread).

The enhanced BIOS ones may be the ones with support for first generation phenom processors.
