Hard Disk Pre-Delay
Common Options : Disabled, 3 Seconds, 6 Seconds, 9 Seconds, 12 Seconds, 15 Seconds, 21 Seconds, 30 Seconds
Motherboards are capable of booting up much faster these days. Therefore, initialization of IDE devices now take place much earlier. Unfortunately, this also means that some older IDE drives will not be able to spin up in time to be initialized! When this happens, the BIOS will not be able to detect that IDE drive and the drive will not be accessible even though it is actually running just fine.
This is where the Hard Disk Pre-Delay BIOS feature comes in. It allows you to force the BIOS to delay the initialization of IDE devices for up to 30 seconds. The delay allows your IDE devices more time to spin up before the BIOS initializes them.
If you do not use old IDE drives and the BIOS has no problem initializing your IDE devices, it is recommended that you disable this BIOS feature for the shortest possible booting time. Most IDE devices manufactured in the last few years will have no problem spinning up in time for initialization.
But if one or more of your IDE devices fail to initialize during the boot up process, start with a delay of 3 Seconds. If that doesn't help, gradually increase the delay until all your IDE devices initialize properly during the boot up process.
