When Instant Music is enabled, the PS/2 keyboard power up feature is automatically disabled. Instant Music CD ROM Allows you to select the CD-ROM drive that you wish to use for the Instant Music CD playback. Configuration options depends on the optical drives installed on your system.

Chapter 2: BIOS Information
SDRAM Configuration [By SPD]
This parameter allows you to set the optimal timings for items 2–5, depending on
the memory modules that you are using. The default setting is [By SPD], which
configures items 2–5 by reading the contents in the SPD (Serial Presence Detect)
device. The EEPROM on the memory module stores critical information about the
module, such as memory type, size, speed, voltage interface, and module banks.
Configuration options: [User Defined] [By SPD]
The SDRAM parameters (items 2~5) become configurable only when you set
the SDRAM Configuration to [User Defined].
2.4.1
Chip Configuration
Instant Music CD ROM
Allows you to select the CD-ROM drive that you wish to use for the Instant Music
CD playback. Configuration options depends on the optical drives installed on your
system.
The above item appears only if you enabled the Instant Music item.
When Instant Music is enabled, the PS/2 keyboard power up feature is
automatically disabled.
SDRAM CAS Latency
(value depends on SDRAM SPD)
This item controls the latency between the SDRAM read command and the time
the data actually becomes available. Configuration options: [1.5T] [2T] [2.5T]
SDRAM RAS to CAS Delay
(value depends on SDRAM SPD)
This item controls the latency between the DDR SDRAM active command and the
read/write command. Configuration options: [5T] [4T] [3T] [2T].
