I'd want to do a somewhat of a sleeper with these: -PCChips M577 -Pentium 233 MMX -3.2GB Maxtor + 850MB WD Caviar 2850 -ATI Rage Pro Turbo AIW -384MB RAM -SB16 PCI (CT5803) -Realtek RTL8139C NIC -circa 2003 Mercedes-styled case made by Linkworld (which isn't bad at all) -Windows 98 SE + 98lite 4.7

VPX chipset should usually work pretty well, even if it's PCChips. Hope it doesn't have fake cache.

Horun - I've tried a P-150 (had that from a long dead Soyo 5TF) , a Cyrix 6x86 non-MMX and still, nada. What's interesting though is that I measured my caps, coils and regulators. I get all corresponding voltages on regulators and caps (2.8v and 3.3v, former was the MMX CPU VCore and the latter is …

Redid the solder joints on all the caps. Now AGP cards work (although a bit randomly), tested with both a Geforce 2 Pro and a Rage Pro Turbo AIW. MMX chips still do not work. I don't get any beeps at all when I power the board on with a Pentium MMX 233. Same chip works on a i430TX mobo.

Rebuilt 90% of a PCChips M577 mobo. Had missing caps, coils, RTC coin holder, missing AT P8+P9 connector, floppy and LPT headers. Sadly no dice: - ATX power doesn't work (won't turn on) - AT power works but no POST - CPU heats up (P233MMX) If anyone has any ideas what to do next, please tell me.

I have 3.27 on both pins of the PSR16C40DT near the SDR slots, and 2.8V on the cap next to it. The one at the corner of the board (to the right of the coil) reads 4.9V (so around 5v). This is without an AGP card. With AGP card (Rage Pro Turbo AIW), I get 2.8V on both pins of the PSR16C40DT, and 2. …

I've been keeping it for a long time (it was upgraded to a Zida 6DLX after the issue happened) but I'd like to try and fix it if possible. Issues: - will POST ONLY with any non-MMX Pentium chip, Cyrix 6x86 non-MMX and any CPU that does not require dual-voltage - will NOT POST with any MMX Pentium …

IIRC from what I've heard, there's a WinME copy that is crash free, with the trade-off being to defrag the HDD continuously. Though I can tell why it's not liked as much, removed real-mode DOS isn't really that cool.

Early ATX PSUs, especially the Pentium 4 era when 200W PSUs with just cheap junk inside were labelled as 400W and sold inside Athlon/P4 systems were a wild west of fire hazards. AT PSUs? Not so much, really. Not all of them are top notch quality but if you come across things like Channel Well, SPI, …
