Thanks all, who wrote me answer. I´m unhappy to work with XP, not mention Vista and 7. I´m fan of ME, but things go worse and worse. You ask me with detailed information about my PC: Motherboard: MSI 865PE Neo3-V, memory: Kingston 2xKVR400X64C3AK2/2G kit of 2, (ME run with 2 modules 1024+512, but I thing, it is not good combination, but if I used 1024+1024 ME crashed), Graphic card: MSI FX5500 TD128LF 128 MB). In BIOS I have IDE Devices Configuration: enabled + auto, SATA Devices Configuration: Enhanced Mode/SATA1 master!!!!!!!! It is very important, it is only one combination, when OS ME is able to boot with: Primary IDE Master - HDD, Primary IDE Slave - HDD, Secondary IDE Master - HDD, Secondary IDE Slave - DVD-ROM, Third IDE Master - none, Fourth IDE Master - SATA HDD. Only two problems are to resolve: reading and writing from IDE HDD is almost fast like at XP, but writing on SATA HDD is very slow. Copying - frozened PC - copying - frozened PC - copying - frozened PC... Many softwares don´t work under ME. Motherboard MSI P4M900M2 don´t support ME. I tried installation, but I must add soundcard to PCI port, but there is no slot AGP, only video-regime VGA is disponible... I apologize you, I have problems with English language, I hope you understand me and thanks for answers
