Hi, can someone tell me what the difference is between Windows NT 3.51 and NT 4 Workstation. I have an IBM Thinkpad 755c and currently have windows 95 installed. However, my display only allows me to go to a colour depth of 16 colours. Hence, IBM says that i must have Windows NT 3.51 to take advantage of the 256 colour depth. Is there anyway to raise my colour depth in windows 95 to 256 colours and can i use Windows NT 3.51 drivers in NT 4?
