Nah, replacing caps on cheap mediocre boards isn't worth it in any universe. Just buy a working one for $5 and be done with it. 478 is basically trash no matter how we look at it. Business-wise, I agree. But as a hobby, I disagree. Just comes down to what one likes to do with their free time. …

Some day I'm going to put OS/2 2.1 on the P60 system that I have. Why? I've always consider the socket 4 platform to be kind of slow, full of quirks, and had a limited lifespan, so pairing it with a slow, short lived OS with lots of quirks seems appropriate, no?

I was doing an early adoption win95 rollout in August 1995 for a fortune 500 company. We were installing Win95 on end user systems as slow as HP omnibook 600 or a Deskpro XE 433. Pretty much anything that could get upgraded to 8MB ram and a 200MB hard drive got the new OS. The end users were happy …

Just because the BIOS detects 1690MB doesn't mean it detected it correctly, especially if you are not using a 1690MB SD. What is the capacity of the SD that you are using? I'd recommend trying XTide Universal BIOS or EZ Drive 9.03 http://vogonsdrivers.com/getfile.php?fileid=1899&menustate=68,66 v9. …

Is the IDE controller chip on the far left a PiC 12885A-125 or VIDE-1 ? Maybe the markings will show up if lit at an angle.

Install the Intel SSD Toolbox. Under View Drive Information look for Word 169, Bit 0 - Data Set Management Supported. If that bit is 1, Trim is supported. CrystalDiskInfo might also be able to tell you. I don't have any experience with DOS trim programs, so I can't help you out there.

Question guys, what happens when you connect pin 34 to a ground pin and then attempt to use the CF adapter/DOM on an older controller? Let's say one that maxes out at UDMA2/ATA-33 or is even PIO-only, will it still be functional like before or is it affected in any way? (other than not being able …

Not trying to nitpick, just pointing out that this "tiny processor" is quite possibly the fastest core on the mobo. And another obvious statement: Solid storage devices have very low access latency and that alone will make them faster than mechanical drives, however well optimized. For example back …

That’s great. That means Windows would be happy to store the page file on the CF Card. I wonder how long the CF Card would last with having Windows run on it with all the write to disk operations. Depends on the CF, the version of windows, amount of ram, your usage pattern, etc. If you were using …
