Another weekend with another small update.

What is this? A new exciting icon in the notification area?

It seems this old 486 system has learnt a new trick!

I have lots of PCI USB cards but when I serched through my storage units yesterday I could not even find the huge moving box containing the lion's share of my non sound or video PCI cards. I really need to move to a large house so I can get all my computers and parts better organized. In the end I found a boxed card I which I can't remember where or when I acquired.

It seems flash storage devices works fine in Windows 95 OSR 2 even if you only get USB 1.1. I used the XUSBSUPP.ZIP driver pack which installed without hassle.

Just curious, what kind of USB flash devices are you using? I just cannot get mass storage working on my Kingston DataTraveler USB flash drives on Windows 95 or 98... I've tried everything, USB supplement in W95, patched mass storage drivers, and so on. I've tried on several socket 7/Slot 1 computers and these god damned USB sticks refuse to work as storage devices in 95/98. They are detected but that's it, no driver works. 😠

The one in use on the picture is some Sandisk Cruzer Blade 4GB thingy but I would assume all works, that is at least my experience with Wndows 98.

I normally use some older USB 1.1 version of the NUSB driver package with Windows 98 as I don't really need USB 2.0 and I have never had any issues.

I added a new addition to this build.

Now everyone can stop wondering where that card ended up. Thanks Artex for the tip!

This is actually my second one but the other one sits in my 286 MIDI jukebox and i felt this build would benefit from one.

I updated the spec and the thread title as much has changed over the years.

Its possible its as easy (or as hard) to get an Intel DX4-100 to run at 3x50 MHz as it is to get it running at 2x66 Mhz as high FSB often limits overclocks somewhat. Im pretty sure 3x44.5 MHz would be really easy with 3.6V or 4V.

Its pity very few boards support FSB speeds between 40 and 50 MHz, I think some revisions of the Asus PVI-486SP3 can do 48 MHz but the PCI clock will still be high enough to mess with the built in I/O controllers, 44.5 MHz would be more useful. Its easier with the older ISA and VLB motherboards with a crystal that controls the FSB.

My Lucky Star LS486E boards only support 1/1 and 1/2 PCI dividers which makes the 50 MHz FSB setting more or less useless. I have another very interesting PCI board I need to tinker with though which could have the 2/3 divider.

Yeah but wouldn't lowering the FSB take most of the fun out of it? Come on, the idea of having a bus running @ 40 or even more MHz is fantastic! Going back down to 33, playing around only with the CPU frequency, is a little boring, but this is entirely subjective, of course.

Guys, I think we all need a modern manufacturer producing a modern 486-compatible (Socket 3 I'd say) motherboard, with PCI, VLB, and ISA slots, very well tuned to handle any kind of frequency on the FSB, from zero to 66 MHz. Then the only problem would be the tolerance of the cards, but the entire CPU-MOBO problem would be solved.
Ah, and of course with 1024K of the best possible L2 cache, still modern-currently built.

Whoa!? And what in the world would even "tuned" or "feipoa bit" mean?????? 😕 😕 😕

High fsb is the best "booster" for a 486 given you can uphold the fastest timings.
Be careful with a 1:1 ratio for the PCI bus when clocking up to 50mhz though - in my experience this is to be rather avoided on UMC based systems.

The fictional Intel DX2-133 is interesting - I got 97.8 fps in 3DBench2 on my overlocked &EW which only worked with 2nd level cache disabled.
Doom gives a rather sturdy 64.8fps(1151rtics), in Quake 14.5fps and in PCBench 28.3fps.
So the intel DX2-133 is nearly as fast in Doom and faster by 4 frames in PCBench as an AMD 5x-133 @150 with 50mhz fsb + 2nd level cache running with "maxed out" timings.

"sunaiac", did you disable the 2nd level cache when running 66mh?
On slower settings it seems to only bog down systems driven by a high fsb.

If you started a new thread, could you paste the link here?

I assume this would be optimised cyrix register bits, e.g. LSSER set to 0, FP_FAST set to 1, etc.

Tuned is highest stable BIOS settings for the given CPU.
Can be variable.
Feipoa bits is using the cyrix enhancement he used in his Ultimate 486 bench as far as I remember.

@feipoa: I totally don't remember haha

Nope tried to have comparable setups.
