This works with my initio 9100uw scsi card and Mustek 1200sp, should work with any adaptec compatable card once the aspi layer is installed. (for 1200sp) 1: Copy the windows folder to c drive (or where windows xp is installed). 2: Run aspi32.exe in aspi folder. 3: Run aspichk.exe in aspi folder, should show aspi is properly installed and fully operational. 4: Run ntsp35.exe After reboot Scanner should work. With some modifications should work with other mustek scsi scanners. You need to have the correct files for twain_32 folder.Download Driver Pack
