TYAN TIGER I7322DP Manual page 47

Large Disk Access Mode
This option determines whether a hard drive with more than 1024 cylinders, more
than 16 heads and or more than 64 tracks per sector is present on the system. Set
this option to DOS if such a hard drive is present. Else, set this option to Other.
Virtually, all modern hard disks have these characters so leave this option at DOS,
unless you know otherwise.
Options: DOS / Other
Parallel ATA
This option determines the controller to be used for parallel ATA devices.
Options: Primary / Secondary / Both
Serial ATA
This enables or disables booting from a serial ATA device.
Options: Enabled / Disabled
Native Mode Operation
This determines whether SATA devices should work in Native Mode or in Emulated
Mode. In Native Mode, the SATA devices are treated as regular SATA devices,
while in Emulated Mode, they are treated as though they were IDE devices.
If you are installing Windows 98, ensure that this option is set to Emulated, else the
installation will hang.
Options: Auto / Parallel ATA / Serial ATA / Both
SATA RAID Enable
When this option is enabled, the Silicon Image RAID BIOS is loaded on system
start up, allowing for configuration of hardware RAID arrays. With the SATA RAID
ROM option disabled, the drives attached to the controller can only act
independently of one another.
Options: Enabled / Disabled
Legacy USB Support
When enabled, the BIOS takes control of the USB ports. Enable this only if you run
an OS that does not support USB (e.g. DOS) or when you have USB hardware like
USB mice that you want to use even before the operating system loads.
Options: Disabled / Enabled
