To prevent data loss, set this parameter to Auto if you are using a hard disk
with more than 528 MB capacity that was previously configured through the
LBA mode. If you use a hard disk configured through the user-specific cylinder-
head-sector (CHS) mode, set this parameter to Disabled.
Hard Disk 32-bit Access Setting this parameter to Enabled improves system
performance by allowing the use of the 32-bit hard disk access. This enhanced
IDE feature only works under Windows 3.x, OS/2, Windows 95, Windows 98,
and Novell NetWare. If your software does not support this function, set this
parameter to Disabled. The default setting is Enabled.
