I have an AT7 and have bought a hard drive greater than 137 GB. The hard drive\nis off of my HPT 374 Raid controller although I am not using any Raid arrays. I\nam trying to find out if my mobo supports 48 bit LBA. Does 48 bit LBA depend on\nmy mobo and BIOS or does it depend on my HPT 374 Raid controller ? Is there a\nsetting in my BIOS or Raid controller BIOS for this ?\n\nAbit has a page about 48 bit LBA support, at\n[URL]http://www.abit-usa.com/faq/mb/check137gb.php[/URL], but the AT7 is not listed on it\nalthough the date of the page is about the same time I bought my AT7.
