DeSilentio, I know EXACTLY what you mean! I had the exact same problem (computer freezes on white text message on black background) with my KT7A-Raid mobo. I could not for the life of me install Win2K Pro on a Raid-0 configuration. But 98SE installed just fine!
The problem: the Raid controller is recognized by the operating system as a 'SCSI' device. And in my system, I also had a PCI SCSI card (Adaptec AHA-2920C) for my CD-RW drive. Well, this card caused a huge conflict in the system. Once I took out the card, Win2K installed perfectly on the Raid-0 configuration. Now, I haven't tried installing a newer SCSI card yet as I ended up installing the CD-RW on another computer, but others have suggested that a newer SCSI card should be more compatible with my mobo.
Now, I'm not sure if you have a SCSI card in your system or not, but at any rate, you are definitely having a hardware conflict with something. My suggestion is to have the bare minimum hardware in your system first and install Win2K on it (0-Raided, of course). Start out with just your mobo, ram, video card, mouse and keyboard. If Win2K installs with just these components, then install each additional peripheral (ie. sound card, network card, etc.) one at a time afterwards. You should be able to come across the conflicting hardware thru this step-by-step approach.
Good luck!
