Well, sorry for the long silence, but I had to solve others problems about others OS on this same machine... Now, it's done : I'm in multiboot with Vista, XP Pro, Ubuntu 8 and Fedora Core 9... Then, I've only to add Win 2K to be ready to work So, a big thanks for all your efforts and your longs and accurates messages here... At this point, I've made a new 2K Install CD using nLite. On this I've integrated the "Intel INF update" and the "modified IMSM 7.x" you talk about in this thread (I've selected all the entries rather only the one about ICH8-M ; maybe it's wrong to do like this, don't know). ... And it doesn't work Drivers loading stage goes well, then I get a black screen with blink underscore at top left corner... And that's all ! So, what could be wrong in my process ? Do I have to just integrate the Intel INF update in a fiorst time, then apply the modified IMSM later : when W2K will be installed and started ? Also, if this can help, remember I've selected the "Compatibility" mode about SATA (rather than the AHCI one) in the BIOS. What's your idea ? Let me know (and thanks again) -- EDIT : well, I've just tried, right now, integrating the ""Intel INF update" only (with nLite) and it remains the same : blink cursor on blank screen after drivers loading EDIT#2 : tried with the Universal ATA driver this time and I get a message saying this during the installation : "unable to find the uniata.sys file" (translated from French). Is it a problem with nLite or something else ?
