BIOS Configuration Utility (RAID EzAssist)
RAID EzAssist, the on-board BIOS Configuration Utility, is used to build
several types of RAID configurations.
The following limitations apply to Automatic Configuration:
• Only one array will be configured using the Automatic Configuration
option.
• All drives controlled by the AcceleRAID 170 board can be different
sizes, but all drives will be configured to the size of the smallest disk
controlled by the AcceleRAID 170 board if in the same array.
• A maximum of 16 drives can be configured into an array using
Automatic Configuration. Any additional drives will become hot
spares. The drives with the largest capacity (if mixed drive sizes are
used) will be the drives selected to become hot spares.
Note
If you want to do anything other than an Automatic
Configuration, refer to the RAID EzAssist
Configuration Utility User Reference Guide or the
Quick Configuration Guide.
To perform a RAID configuration with the Automatic Configuration option
using RAID EzAssist, do the following:
1. Power on the computer. The AcceleRAID 170 controller is furnished
with the BIOS enabled by default.
2. Watch the messages on the screen for the following prompt to be
displayed:
Press <ALT-M> for BIOS options
Wait approximately 5 seconds. Do not press any keys at this time.
