I'm playing with older systems from familly members to learn. I have a Tyan Trinity 400 S1854, 500 PIII, and a 3DFX video card. On start up It recognizes the 3DFX video card, Award Modular Bios, the MOBO, the CPU, all the memory installed, Award PnP Bios and then goes to a black screen with a blinking cursor in the upper left corner and stays that way. Initially it would not recognize the primary master so I rest the CMOS then it showed the Primary Master Drive
