Getting Sun Sparcstation 10 to recognize its graphics card

Working from this page to configure my sparcstation 10 after NVRAM replacement: http://www.obsolyte.com/sunFAQ/faq_nvram.html ...but curious is there an installation manual or whatever specific to the video card in my system, a TurboXGX with STP3010GPA chip http://vintagecomputer.net/sun/SparcStation-10/Sun_STP3010PGA_TURBOXGX.jpg I have Solaris 4 installed. I am guessing around trying different things. With help I have the OS installed but so far I can't get the system to recognize the video card and Sun keyboard. With these installed it freezes the system...so, I am using a serial terminal to interact with the system. The video display I have is an SGI GDM-20D11 Eventually I'll poke through to the solution, this is my first Sun box, up to this point they were "too new" but I'd like to learn how to perform a system install. If I find the answers I am looking for I'll post here. Bill
