the motherboard BIOS instructs the card to act as the boot device.
Staggered Drive Spinup – This option is disabled by default. Enabling this
setting will instruct the card to power up the hard disks, sequentially (one disk
approximately every 2 seconds). Not all disk support this setting – consult
the disk documentation for more information.
Warning: Western Digital hard disks do not support this setting. Enabling
this setting is not recommended. If enabled, these disks may not be detected
by non-RAID controllers.
