My questio/problem is this: My DVD/CD-ROM (LG some thing another) is installed on the IDE1 port as primary slave (jumpered) and the WD Raptor is jumpered Master and connected to the SATA1 port on the mobo. In my BIOS the Raptor is listed as THIRD Master and the DVD/CD ROM is listed as SECOND slave. Not sure why that is or if I need to correct that? System runs nice, XP loads quick etc. Do I need to change that? System specs. above mobo and HDD, Athlon64 3500, 1GB OSZ platinum DDR (2X512MB), GeForce 6600GT (I know, need 7800 GT soon). Any help, suggestions greatly apprieciated. PS, I up graded the on-board LAN drivers and nVidiaGF4 drives via the MSI live update application. That was slick and made HUGE difference in system speed and stability. This system was just built by me on Saturday morning , i.e brand spanking new and already had to upgrade chipset drivers to get it to work like a real computer.
