NT Server

Here’s a strange one… I upgraded an HP P133LH with 128 mb ram to Windows Server 4.0 and have never been able to boot the server without a Boot disk since then. When I try to start it with out one, all I get is a black screen with a flashing cursor… I’ve tried a new install with a different Dir, no luck.. did the virus scan, clean.. Installed the latest and greatest drivers and bios, no luck… anyone ever hear of this?
Thanks,
John
