Re: Old hard disks lifetime?
Posted on 2020-08-09, 19:08
I think the "expected" lifespan of a hard drive is only a few years, so it's amazing to me any of these old hard drives still work after 20 or 30 years.
Re: overwhelmed by motherboard and CPU selection for 486 build

The original Warcraft 2 only required a 486/33 processor (not sure if it even required a FPU, SX-33 may have worked). The Pentium 60 requirement is for the Battle.net edition. Even so, I don't think it would care that much about the FPU speed, it's not a 3D game. If you found an old 5V board that …

If you're just browsing at this point, why not find a nice board that supports the late 3.3v processors? Then you can put whatever you want in there. The cost difference between a DX2 and DX4/586 is basically nothing. I would also get a board with the 72-pin memory slots. PCI is nice so you can use …
Re: Will WinXP *run* on a 486?

The real question is why would you want XP running on a 486? NT4 and 2k were already taxing enough as it was. Even on my PIII-700 Windows XP felt like a dog compared to 2k. I'm still trying to get this connected to my distributed computing client (BOINC). It's not going to add any meaningful …

Thanks for the replies! Guess Windows 2000 is the latest and greatest for this machine. I do have Win2000 SP4 running on it already. Nice little OS and surprisingly usable even on a 486.

Sorry, I probably wasn't clear on my intent. If I installed WinXP on a Pentium Overdrive Socket 3 system, then replaced that Pentium overdrive with a 486 DX4-100, would XP run?
Will WinXP *run* on a 486?
Posted on 2020-08-06, 20:34
I know it will not install on a 486 (installer will check), but would it *run* on a 486 DX4-100, if it were installed using a different chip (like the Pentium Overdrive)? Or installed using a different computer? I'm sure it will be slow but I'm curious if its possible.

I figured they might have changed die caps if it was a late production chip. It should be obvious after removing the cap if the die is the right size. But is there any good explanation why this chip would not work in my system, yet my write-thru DX4-100 "&E" works just fine? If someone else has a …

http://www.cpu-world.com/forum/viewtopic.php?t=13445 Wonder if some useful information can be obtained from this thread? Yeah I saw that, was interesting. Unfortunately, nobody responded with test results in that thread. CPU posted once at 5v and 33 MHz FSB, but locked up right after the memory …
Re: Western Digital Research 20,000RPM Hard Disk
Posted on 2020-08-05, 19:05
All of Western Digital's "secret sauce" is related to their mechanical disk technology, so it's not surprising they would continue to push it. If it can compete with SSDs in some workloads with a super fast mechanical HDD, then they have a product nobody else has in the market. If mechanical disks …

I'll try it at 5V, 33 MHz FSB and see what happens. If it doesn't, I'll try removing the die cap and exposing the core to solve the mystery

Would be interesting to compare this to the new QLC/PLC drives (the high capacity, low cost, relatively low performance SSDs). A mechanical disk will always get stomped in certain workloads (lots of random access) but it might be competitive in others.
Re: 486 cache & CPU upgrade questions

This looks like the same layout as my IBM Valuepoint (which I thought was a proprietary form factor), was this some kind of standard? There are jumpers for 3.3v operation but looks like you would need to add a voltage regulator.

If this was actually a 5v DX2-66, what is the lowest voltage it would boot up with? I tried removing all cards, all memory except 8 MB, all IDE drives, etc. I got a blinking cursor once, nothing the other 20+ times I tried. Never posted.

Nice to see a fellow Valuepoint owner, seems pretty uncommon these days! I am not sure that the actual cache chips were original with the system. It's possible I swapped them out a long time ago (I had a lot of old PC equipment and it migrated between systems). But it does recognize 256k cache. I …

Something doesn't add up. 1) Make sure you have a good battery ( test with multi-meter ) 2) Remove all cards and devices from your motherboard but the video card. 3) press down on cache …

Thanks for the reply. I'll try and let it run overnight. I want to see if this machine will connect to World Community Grid just to see if it's possible, I couldn't get it to connect on Win98 (think W98 is just too outdated at this point even with the kernel extensions).
