Sure they do.

UATA/33 cards for PCs or Macs are limited to 128 GB (131,072 MB).

UATA/66 cards for PCs or Macs are limited to 128 GB (131,072 MB).

UATA/100 cards for PCs or Macs without the update are limited to 128  
GB (131,072 MB).

UATA/133 cards for PCs or Macs have no practical limitation.

The LBA48 properly was added as a requirement on UATA/133 cards, but  
was back-fitted to a few UATA/100 cards (Promise, and perhaps  
another ... ACARD, I think) through a firmware update.

The manufacturers of UATA/33, /66 and most /100 cards never went back  
and offered an LBA48 update for their cards, hence the 131,072 MB  
restriction is permanent on those cards.


Intel mobos with on-board UATA/66 or UATA/100 ports also have no  
limitation, which is perhaps one reason why these mobos make such  
economical Hackintoshes. Apparently, Award, or whomever, elected to  
include the LBA48 property within the BIOS of all of its offerings  
for Intel products. Gigabyte G31, P35, etcetera, etcetera, etcetera.  
Also, incredibly enough, the MSI Saturn, which is a complete  
barebones system available for about $60.
