Hi guys, I have a problem, which might be easy for some of you guys. My system config is : Board Intel DP35DP (Media Series). Core 2 Duo 3.00 Ghz, 2 GB DDR2 RAM, SATA HDD, SATA Optical Drive (Samsung), USB Mouse and Keyboard. Nvidia GEForce 7 Series. Current OS : XP Pro SP2 (32 bit) I am unable to install Windows Server 2003 on this system, have tried many times.. always got BSOD which says IRQL_NOT_LESS_OR_EQUAL something like that. BIOS set to Legacy with SMART option Disabled. I am not planning to RAID or use AHCI, just wanted to use this single HDD of 250 GB and dual boot. W2K3 with XP. At installation all went fine till it reboots for GUI mode when the installation is installing devices... then it blink and BSOD. Never use F6 coz Mobo doesn't have FDD port. Any one knows what the prob could be or does anyone ever had this kind of issue. The last installation setupapi log file reads #-011 Installing section [Processor_Inst.NT.Interfaces] from "g:\windows\inf\cpu.inf". #I054 Interfaces installed. #-166 Device install function: DIF_INSTALLDEVICE. #I123 Doing full install of "ACPI\GENUINEINTEL_-_X86_FAMILY_6_MODEL_7\_1". (The last 4 lines) The setuperr doesn't show anything.. Please anyone???
