I'm going through a similar process myself (see my 286 is dead, long live the 286 thread: https://www.vogons.org/viewtopic.php?p=925540#p925540). I also had an original 286 board that was my first computer and used it on-and-off for many years. After putting it in storage 6 years or so ago it now …

Iam not playing with such devices. Iam just a regular guy who only owns cpus and motherboards.. And building a working system out of it.

It also could be that the ROM on your EIDE PRO was to old. I have the same cards over here. And my card uses V2.0 of the rom. Yours is v 1.03.. could make a difference. Thats why manufacturers updating their roms. One of my cards works flawless. Only have to test the other (new in boxed one) If its …

I had to set this controller to CP-344 and WD93048-A type drives for my CP30084e drive. On normal operation setting the drive had some fail issues on the bios setup program - hard disk utility could format it with normal operation mode. But couldnt do a media analysis nor Auto interleave function in …

It depends if you knowing the original URL from back in the day.. If you know that, you have an option to look at it on archive.org.. Maybe you find a working link or a file name where to google at.

So... I'm having RAM issues while trying to set up another Suntac board. This particular board supports SIPP memory, but since I only have 256kb SIPP modules, I'm trying to make it work with 1Mb SIMM modules in SIMM holders inserted into the SIPP slots. The DIP switches for memory are set correctly …

All PII can run with just a chunky heatsink if not overclocked. Many were originally shipped that way. A lot of slit 1 P3 that I have seen are also fanless. I always thought that these versions of the Pentium II where only used for OEM market. And i know that Dell would use a type of fan duct …

286 is only better for speed sensitive games. like wings of fury (dos). Its running to slow on a XT class machine, but its to fast on a 386 DX machine. Other benefit is, you could install all 1989 - 1991 games on it instead of your 386, so it uses less disk capacity on the 386 machine so you could …
