Maybe this helps you... http://unattended.msfn.org/unattended.xp/view/web/34/ Take a look File Attachment too. My board(Asus K8V) works fine with all this... -expertti- EDIT: Look File again. There is another drivers now. Put then in your "viasdrivers" -folder. I have used earlies and newest nlite and RVM_Intecrator. There is not any bug.. In my case, it looks like this >"InstallRoot"\$OEM$\$1\Drivers\VIASRAID VIASRAID- folder include this: viasraid.cat viasraid.inf viasraid.sys And you have to make and use WINNT.SIF also. Put this file in \i386 -folder. -expertti- VT8237_Chipset.zip
