563 The advanced error reporting(AER) capability is "NOT" provided by
564 ARC1200/1201/1202 SATA RAID controllers cards.
565 If your card is one of ARC1200/1201/1202, please use the default setting, n.
566 If your card is other models, you could pick it
567 on condition that the kernel version is greater than 2.6.19.
