I was able to use the wayback machine to look at the diamond multimedia support webpages from back in the late 90's and early 2000's and the proper driver file is 964c03.exe if anything were to need that information in the future.

Does anyone know where I can find the MS-DOS video drivers for a Diamond Stealth 64 VRAM? The Vogons' library has drivers for Windows 3.1 and Windows 95 but not DOS. I have searched the internet and I get very mixed answers. Various websites recommend different drivers and none of the websites seem …

I received the POST code analyzer card today and it gives it gives a couple pieces of information. First it includes a speaker. When i hook the speaker up the motherboard, it does not make any beeps during the start up process. When looking at the numerical post codes, sometimes it will show that # …

Thank you everyone for your input. I unfortunately do not have a PC speaker to hook up to the board at the moment, so I am not able to tell if it beeps or not. I have some of the small PC speakers and an ISA diagnostics board coming in the mail this weekend. The CMOS battery is new. This board is …

I am working on building a 486 PC and I am having trouble getting the motherboard to do anything at all. In an effort to troubleshoot what the problem is and leave as few variables as possible, I was wondering what is the minimum amount of hardware that needs to be installed on the motherboard. For …

I really appreciate all of the comments and research on this. I see both sides of the argument. The cosmetic differences in the processor I received compared to known real 486 processors does give reason to be suspicious (especially the lack of the registered trademark sign), but I guess it is …

The auction title is "Intel DX4 iCOMP indes=435" and the sellers username is "worf1"

Yep, He has two more for sell.

I purchased a 486 100 Mhz processor from ebay and I am suspicious that this processor is fake. I wanted to get y'all's opinion before I claim the ebay seller is selling fake products. Attached are pictures of the processor. The things that look odd to me are: The "Intel" logo is incorrect. The "e" …

Thanks for the reply Whiskey! I went home last night and tried working on this some more. I made a three pin jumper to connect pins 15 and 17 to simulate a three pin switch, but nothing changed. I also retried jumpering pins 15 & 16 and pins 16 & 17 and restarting the computer with each jumper …

I am just about finished building a 486DX4 100 MHz computer using an AOpen VI15G motherboard. The only thing I can not get to work is the Turbo Button. The LED for the turbo light stays on all of the time despite the system being at full speed, and the switch does not change the system speed. I am …

To update: I have had some unexplained success! I spent over an hour with rubbing alcohol and a plastic scraper getting off the old thermal adhesive tape. It eventually came off and I only lost a little of the 486 label paint. IMG_E2455.JPG I know cleaning this adhesive off wouldn't have anything to …

Unfortunately, the ISA slot diagnostic card wasn't much help. It is just showing dashes, which I take to mean that the POST process doesn't even start. I have ordered another 486 processor to try. I have already swapped out RAM, Video Cards, Cache, and Bios chips so that is about all that is left to …

I appreciate all of your help with this! I may have found the issue with my motherboard. When I purchased this board it came complete with RAM, Cache, and Processor. The processor had a heat sink firmly attached to it, so I couldn't tell exactly what it was. The motherboard came with the jumpers set …

Thanks Nvm1! I appreciate the advice. The RAM I am using was advertised as FPM when I ordered it, but I will Google the actual part numbers tonight to make sure that is what I actually received.

I am trying to build a 486 PC for retro gaming. Below are the parts being used. When I put everything together and switch on the power, nothing happens. I don't get any picture on the screen. I don't get any beeps from the PC speaker. Nothing. All of the jumper setting are appropriate for the …

Thank you for the quick reply. I have read that thread you linked to before and there were a couple of things that I questioned. First, that person said that their board had a label on it that said "VI15DX4", but mine doesn't have that label, at least not anymore. So, I didn't know if mine was the …

Hello! I am a first time poster to this forum, and I really appreciate you help. I recently received an old AOpen VI15G motherboard that I am going to use to build a retro PC for DOS gaming. I am trying to figure out if this motherboard will support a 100 Mhz DX4 processor or not. All of the …
