Hello, I have been getting error msgs from nLite saying these three files are corrupt: symc810.sys, symc8xx.sys, and viaide.sys. If I proceed my XP install dies with viaide.sys corrupt. Am I doing something wrong? Here is what I am doing: 1)use nLite to slipstream XP SP3 to a disk copy of my install cd (sp2) 2)use nLite to integrate hotfixes since sp3 (from Windows Updates Downloader) 3)use the latest driverpacks base to slipstream the latest driver packs DriverPacks: Chipset, CPU, Graphics A+B, LAN, Storage, Sound A, WLAN Mass Storage in text mode (so will see sata at boot) Slipstream Method 2 (allows more drivers though I don't know the limit on 1) Finisher Method: GUIRunOnce Disable KTD (default) Enable QSC (default) (this default has changed since last I did this) DriverPack Graphics A, DISABLE BOTH: ATI Control Panel (Control Center needs .NET) 4)use nLite to remove many components including these drivers: drivers: ATM 150 KB drivers: ISDN 5.77 MB drivers: Scanners 7.22 MB 4)use nLite to configure unattended install and create iso This is the step that produces the corrupt file errors Can you tell what is happening to produce the errors and how I might avoid the errors? Can I simply copy the files from somewhere? Would I need to compress them sys to sy_? Thanks very much, Jerry Gordon
