Nvidia has silently uploaded a new build package of the unified nForce 1/2 driver package onto their servers. This update comes right after the last official release 2.41, see previous story
here. Although we have no nForce solution available at Warp2Search, we suspect that Nvidia reacted to users reporting on errors with the included IDE miniport driver 3.40 (Full) which was included in the 2.41 package.
