Hi guys , i have the following reg :
CPU : Intel Core 2 Due E8400 @ 385 X 8.0
Motherboard : Asus Maximus Formula Non-SE  
PSU : Zalman 750W SLI v2
HDD : 1 WD 7500RPM SATAII 160GB : SATA configuration in BIOS is : AHCI  
 
My PC boots in 30-35 seconds , i know since i have only 1 HDD its gonna take longer time than if i have 2 or 2 HDD's , but the problem is not @ windows loading level (windows bootscreen) , its @ the ASUS BIOS logo level , it takes @ least 10 seconds , and i know people almost with same Hardware configuration  that i have that their PC's boots in like 12 seconds or less , so please does any 1 have an idea about this ??

yes that sounds about right
lots of things to check and load
 
regardless of whats hooked up it still checks, the ide from marvel shows it down
 
there is not ide on the newer intel chipsets, the ide is usually where they hang
 
 
you might turn the ide off and use an sata dvd

Anso - Regular use of a good aftermarket Defragger that does system files on start up will make a difference.
