Primary IDE Master/Slave & Secondary IDE Master Slave?

rahulkhajuria

1) When I start my P.C. , everytime there is blank in front of Primary IDE & Slave & there is some value written in front of Secondary IDE but again blank in front of Secondary Slave .What does this mean ?

2) Although Hardware Detecting Utilities say there are four 1-GB DIMM slots on my system , actually I can see only two upon physical inspection . I have a single 512 MB DDR DIMM at present but plan to buy & put in two 1-GB DDR DIMMs . How do I enable Dual Channel "Memory Retrieval" on this system ? MotherBoard is MS-7101 from MicroStar & NorthBridge is Intel i865P/PE/G/i848P Revision A2
