Did you: - use a cable with the twist, and set the drive for ds1 - use a cable without twist, and set the drive for ds0 Did you use a 360k image? The standard 51x0 FDD controller cannot handle HD drive speed.

My ultimate P-MMX is the one that clocks to 4x100 on an agp board. Two of my 200s seem to be able to run stable with a slight overvolt to 3,0v and some copper based socket A cooler. Tested on my pc chips m577 test board, 64MB pc100 sdram, Nvidia geforce mx440 for a few hours and running smooth :) …

Little background. Recently I bought three random old looking hard disks. Pictures were low quality but it seemed like a nice set. It turns out there's a WD 93028X, a miniscribe 8450XT and Seagate ST3250A. Now the first two are XTA disks, so obviously I won't even try to attach them to a standard …

For the stacking, you may like to read about the Ibm 5151 unit, it acts exactly that way :) As for the ram expansion, I have a ram card that takes 4 banks of ram, either 64kbit or 256kbit chips, and a dip that sets the starting offset. That maxes out any 51x0 8088 and clones. I still want to use it …

Well that answers the question I guess :p There's also an Asus branded isa based SB16 vibra card, in case you want the compatibility. I had one earlier. Sold it, as I'm not too much into vibra cards, though.

The "370cpu" definitely is Coppermine compatibel. I have one in my P3B-f at 980MHz (fsb 140). The board should support it as well, as the slotket is dumb a.f.

After formatting i also run fdisk /mbr command, to be sure the mbr is ok. This may be the problem sometimes, wouldn't be my first. Also, you may want to try with different dos versions if this won't do. Maybe there's something fuzzy going on when running this specific sys command.

From time to time Evercase.co.uk may have a batch of clean, new cases equipped with AT power supply (or at to atx cable) and one of these AT backplates. The standoffs can be set to AT positions too. Ready to for your (baby) AT style motherboard.

You may try to set the cpu at 100MHz, that relieves all stress on it so you'll probably the that one out. If that works you may have encountered one of the many remarked ones. Mostly they will run fine but some will struggle. Or did you set the main board with split voltage? That's ment for the MMX …

This does seem to be an issue with retrobrighting. People reporting that the yellow discoloration will return over time. I've decided to accept the yellow patina on older cases. It's just part of what makes retro systems retro. Alternatively, I've pondered trying out airbrushing instead of …

Basically every atx PSU will do. There are not many 486s that burn away more than 80W. That's the 12v line included. So everything above 200W should have a 15+ amps on the+5v line and that's fine. Just make sure you've got a good PSU: some crappy stuff will not regulate the +5v line very well …

The Rage IIc was often a cheap way of getting ok video and performance, but it never was intended to be top end. The MX4000 is a lot better imho. It is not too different from the MX440 and still has the relatively low power drain the motherboard expects. If you go Geforce 4 Ti it might demand too …
