I've been searching for a long time to solve my Nforce4 problems. I was really excited finding a possible solution, but after burning 5 setup CD'S I started wondering does this solution actually works? Well perhaps I am doing something wrong....? My system: Motherboard: Asus A8N SLI Deluxe Nforce 4 (newest BIOS) Processor: AMD Opteron 165 Memory: 4x 512MB RAID: 4x 160 PATA RAID 0+1 Array (Healthy) Hopefully somebody can tell me what I do wrong if I explain all steps I took creating a setup CD. 01. Downloaded Nlite (newest version) 02. Downloaded Vistabeta2 drivers (also tried other drivers mentioned in the tutorial) 03. Copied all content of my Windows 2003 installation CD by using Nlite 04. Selected "insert drivers" and "create bookable Setup CD" Inserted "nforce_vista32beta2_english\IDE\driver\legacÿ" "Textmode driver" (in my last attempt) 05. verified changes and burned the CD directly by using Nlite. 06. insert CD, run setup The result, the 4 hard disk drives installed are still shown separately. (it should be one partition of 300GB) One thing I have to mention, is it really necessary to slipstream SP2 into the Windows 2003 setup CD? So far I haven't done. Can somebody give me tell me what I am doing wrong?
