I have a list of Alt-Codes for special characters in DOS. As I was holding down the Alt key and typing in random numbers to see what I could produce, somehow a table popped up with the special characters listed. It also displayed the 3-digit number for each symbol as you moved around in the box. I …

My monitor is a CRT from he early 2000s. It doesn't have a way to remember settings, but on the other hand, isn't DOS and windows 95 set to 640X480 the same thing? It really shouldn't be this complicated. My other ISA video cards work fine. I'm trying to install the full package of the utils for …

Just tried changing it. That didn't help. I had an issue with the Diamond Stealth card I used previously (flickering) so I bought this other one, an APAC brand S3 ViRGE DX. While this new one fixes the flickering problem of the old one, it's created the new issue I mentioned above. I can't keep …

I have an S3 ViRGE DX card. When in dos everything is fine, but in windows 95 there is a small vertical black area on the left of my monitor where the cursor stops. Conversely the right side of the image is out of view (where the time is). I can adjust my CRT to move the whole screen over to the …

Something is bothering me. I have a weird, faint scan line thing going on on my monitor. It only happens in W95 with my Diamond Stealth S3 4mb Pro card. I'm using a CRT monitor. If you look closely you can see lines moving downward. It's kind of like recording a CRT screen but it doesn't look that …

Very good condition! Is that Varta battery original? The battery is no longer with us. R.I.P.. I took these pics months ago to remember how everything was plugged in because I soldered in a new battery. It now has a cellphone battery pack :) See the attached for the BIOS. I verified it 3 times. …

There's a sticker on it that says "MSI: 878945" I'll need to tear it down to take pics. I have the bios and keyboard chip out. Here's what they say underneath: S 27C512 -12 FA 230C505 9114WG What kind of chip is this? I'll need to select in my software before copying. I don't see an actual brand on …

Hey guys, I've got an AMD 25mhz 386 integrated. I see a couple chips on it: an AMI BIOS chip and a keyboard chip. Not sure there are any other chips but will take a closer look. This is what I get when booting: Top: ROM BIOS American Megatrends Inc A423073191 Bottom: American Megatrends Inc 30-0501- …

A little update: the Turbo button was set to either on or off, I don't remember, and that halted the ESCD Update. When I pressed it to the other setting, it worked fine. Not sure which setting was which but I just unplugged it from he header along with its LED an now all is back to normal. Even …

I had nothing plugged into the SMI pins. Turns out it was the Turbo cable/pins. I've never set up turbo before. Maybe I'll look into it. For now I'm going to leave both the Turbo and its LED unplugged altogether. Will keep building the system back little by little and give an update in a bit... PS: …

Guys I think I have CRACKED THE CODE!!! Not out of the water yet because I have to test more but I just got it to work 2 times in a row. It isn't the bios. It isn't a bad cap. It isn't bad cache. It isn't bad PCI/ISA cards. It's... The Front Panel Header. This whole time I'm trying to hunt down an …

Look at the bigger caps at the top left and right. These are near the CPU. Ignore the smaller ones in the middle. The right one has a slightly bulging top as compared to its sister on the left. I doubt this is much of a problem but it's the only one that looks suspect. I also did a visual trace and …

OK, I got the floppy working and successfully used uniflash. It didn't help, however. Still stuck on Updating ESCD. I noticed that when no cards are in the system (even a video card!) it seems to boot and I can tell by the HD crunching away. That's probably because by chance, the last time ESCD …

I moved the jumper to the off position and still no dice. Going to try uniflash now... Syntho one more thing. Try to unplug HDD out just to see if it will go through this damn ESCD... Yep, tried that too. Also, I just discovered that the alternate bios I tried doesn't let the floppy drive work. …

Syntho I may have solution for You. What cache chips are installed on mobo? On one of my FIC-PA Mobo which I bought as non working I had corrupted cache modules. The option was to set 128, 256, 512 or off. Only 128 or off option work for it. It was freezing at ESCD same spot as on Your case. …

I tried your EEPROM fix. I was met with 3 beeps, then two more beeps, and the two beeps were high and low pitched. I'm looking up uniflash. The software download link isn't working on the official site. It seems to be DOS-based, and my programmer is a USB model. Not sure how to go about it but I'm …
