Hello all! I'm not sure exactly where I schould start. i'm working on win "xp pro x86" and would like to do a fresh install of "xp pro x64". so.... I have been trying to gather as much info as i can & reading up on using "NLITE". I believe I have to of course add all the nessasary drivers not found on install disk, or to say the least amount to get it up and running; ether by the f6 method or slipstreaming with "nlite". And the saga begins!. System specs are as follows: o/s: win xp pro, ser pack 2 (build 2600) Mainboard: Tyan thunder "k8we s2895" processor: 2.40gz, amd dual core opteron, (2 installed) Ram: 8 gig drives: 1 dvd, 1cd on ide, 1 floppy. 3 hddv's: (storage), 2 set for raid 0, all ran on card: "siig" sata 4-channel raid controller. 2 main drives ("c"), both in removable drv trays. Ok, if i can use "nlite" to add drivers for x64 disk, can i do this while in x86?, if not im back to "f6". and im getting a little confused about which drivers i have to add. I have gone to "tyan's" website and got all x64 drv's listed for Mboard. Before i start, I would appreciate any advice! Maybe im posting in wrong forum, if so i apoligize ahead of time. I forgot to say " im trying to install xp pro x64, with rel date:june 2006, (new) sp1?. Allso would like to say everything has been working neer flawless in x86 so far. resp: Spicey
