I have been using OSS successfully on another PC for about a year now, but am replacing that PC with a new build. I setup XP, installed DD 10 build 2160 installed OS Selector and have 2 working OS's except that OSS is Extremely Slow to respond. It takes about 10 seconds to register a mouse click. I set the Mouse options to PS2/USB but no change. I did install the OSS to my second drive (I don't remember if I did that last time or not.) I have 2 640GB drives, the 1st drive with 3 100GB primary partitions for the OS's, and the 2nd drive is 1 Primary 640GB. OSS was laggy right after install. On my original PC if I used the keyboard arrows to move the selection between OS's or the mouse it was instantaneous and the boot into the loader was faster as well. Should I have selected the 1st drive for the install? Anyone have any suggestions? Bios settings maybe? Thanks for any help.
