Thanks for the detailed explanation. I got through a full cycle of memtest86+ with caching above 16MB and memory relocation. Worked great. I have also found that there's an MR BIOS for this chipset that is supposed to increase performance. Going to give that a shot too.

Oh wow, thanks for all the info. I tried it, but unfortunately it would not POST with W4/W5 set, or either individually. I was however able to enable caching above 16M with AMISetup. How can I test if my machine will crash? What are the downsides to disabling relocation? Is there a difference …

Well, the board says 34DMU=50hl2-l4-vb p353F0010B Made in Taiwan I can't find anything on the internet about it. The chip appears to be a um82c481af. If it wasn't caching, wouldn't CACHECHK say something like "It looks like megabyte #16 isn't being cached"?

I have a 486DX2/66. My BIOS defaults to an AT Bus Clock of CPUCLK/6. Does this mean I'm overclocking my AT bus to 11MHz, or does that mean my CPU is running at 50MHz?

The CF card in my Pentium died yesterday. I was wondering what the current best practice for storage solutions for a PC of this vintage is. I did the CF-IDE thing, maybe 8 years ago. Put a 32GB CF card in it, and was pretty happy even under Windows 95. Large CF cards haven't really dropped in price …

No. Switch to Linux for anything that matters. XP is nothing more than a game launcher at this point. I mean, just look at the amount of work it takes to keep XP safe. Ain't nobody got time for that.

The best thing to use to remove thermal paste is a non polar solvent like naptha(aka zippo fluid).

Please be careful recapping your needles! Don't hold the cap when recapping. Place it on a surface, put the needle in and pick up the cap with it. Then secure the cap. This will prevent you from missing the cap and jabbing yourself with a very sharp and probably dirty needle.

Yes, absolutely buy a spare of anything you can. Most PC equipment from the 80s and 90s has already been destroyed, and the only ones who care about it are weirdos like us. Your vintage PC will break down eventually, and if you don't already have a parts machine you'll probably be SOL. But yes, you …
