You guys are awesome ! I'll try DACs' replacing and (if this won't change anything) I'll try replacing the capacitors. Unfortunately - I have no oscilloscope and I wouldn't even know how to use it (I'm good in soldering, building some arduino-based devices, but that's all I know). However... I have …

https://www.vogons.org/viewtopic.php?t=38155 Thanks for the link, but I've already read this topic. However, they say that some of the cards will have a problem with LCD screen. In my case - after replacing the VGA card with the very same (I mean identical) model - the issue is gone (I have three …

Hello All, Yesterday, I've built a new 486 PC. I have a bunch of ISA GPU's to be tested and one of them is Trident GPU with Trident TVGA8900C chip. The card is giving an output to the screen and in DOS everything seems to be fine. Even in Norton Commander (with blue background) the GPU seems to be …

Guys, you're genious! I've took my COM port out of the case, and checked it (as I've wrote in previous post). It turned out, it has a "supermicro" pin layout (1 6 2 7 3 8 4 9 5). Next, I've found some old COM port in my basement and checked it - pin layout is 1 2 3 4 5 6 7 8 9. Should work, but... …

Hi Guys! As usual - your help is irreplacable :) My motherboard ain't got no pin numbers for COM port header. The only way I can tell where pin1 should go is because there's a rectangle surrounding the header and one of the "walls" is thicker than the other ones as can be seen on the below photo: …

I belive there are two types of COM port headers, there's a chance that your COM port brackets are wired for one type while your motherboard has the 2nd type. Thatnk you, I didn't know that. I hope my mouse didn'got fried because of this... Is there any way to re ognize which RS232 is which? It …

Hello All! Recently, I've built a PC running a Pentium 166MMX processor on a Powertech MB532 motherboard (AT format). The problem is that there is almost no information on the internet regarding this mobo and I have a serious problem: it seems that my COM ports are not working. The mobo has its own …

Hi All, I see there's a lot of S3 cards lovers here ;) I have a S3 Trio64V2/DX PCI card that I bought few weeks ago for $5. My rig is Pentium III 600 (Coppermine) + 640MB RAM. What I'm trying to achieve is to get some decent screen resolution (1024x768) with 256 colors in Windows 3.11, but every …

Thank you @Jorpho for the reply. I'd rather exclude the virus as a) this is a fresh system, b) when I'll comment out SB drivers and add NOEMS option back - everything works fine (of course, except for the sound ;) ). By "the computer won't even boot" I mean that if I'll leave sbeinit in autoexec.bat …

Hi Everyone! I know it's an old thread, but I have a problem regarding an issue described here: "Not enough memory to run this program". I used EMM with NOEMS parameter and everything was working fine. But I have recently added a SB Live! card and the SB16 emulation requires EMS (othewise - the …
