Hi, I'm trying to install an 80Gb hdd on an old Pentium 3 and I've run into a few problems. (Yes, I know that's an awfully old computer that maybe should be in a better place than a desktop, but computers tend to have a very long life here in Bolivia... ) This is what I did: Removed old 20Gb hdd Connected new 80Gb hdd POST would stop completely when trying to detect hdd Used jumpers to reduce capacity to 32Gb Voila! I was able to boot and start XP install from CD. Formated hdd during XP installation (NTFS, complete format) Windows copied necesary files, and reboots automatically This is where my real problems started, because now the the POST stops again when trying to detect the hdd, I've tried every jumper setting, but nothing works. When I disconnect the hdd I'm able to boot from CD, but that doesn't help me fix the hdd. Any ideas what I could do? I'm considering flashing the BIOS (using bxc00920.exe from here), but it says "compatibility with IDE hard drives up to 65 Gb" so I guess it wouldn't help.
