I think it's a shame a mega corp like Microsoft can't actually finish porting their Windows control panel functionality over to the new UI after 10 years.
Re: SB Live! not working in FreeDOS

SB Live and earlier Audigy cards use EMM386 port trapping to emulate the ISA sound blaster interface. FreeDOS EMM386 and JEMM don't use the same interface as the versions from MS-DOS and PC-DOS (DR-DOS compatibility unknown). MPXPlay supports SB Live hardware natively. If that works, try using a …

Re: Capacitor replacement rules?
Posted on 2022-08-22, 01:41
I already explained it can throw off a control loop, like a switching power supply regulator feedback loop. Some switching power supply chips have a limit how large (or small) a capacitance you can put at the regulator output or the output voltage won´t be stable, it could start to oscillate or …
Re: Capacitor replacement rules?
Posted on 2022-08-22, 01:23
OP here, thanks again for the responses guys. One more thing, why is it wrong (as a general rule) to replace a capacitor with one that has a higher capacitance? Wouldn't storing more charge be better generally (like having a larger battery)? As I said before, it depends but you can generally go a …

Or DOS. What is "based on DOS" in Windows 11? Kind of the point. DOS was extended into Win 1.x-ME. From there, APIs were ported into NT. Most of the older legacy APIs began to be retired as Windows moved to 64 bit, predominantly starting with Vista (I don't consider XP 64 bit to be mainstream). In …

I've run NT 3.51, NT 4, and Solaris 8 on my dual coppermine Epox machine. Much the same as yours, except it's fully populated with 1gb of DIMMs. The level of performance is almost pornographic. Enjoy.

CPU-Z.jpg And here are some benchmarks. Basically, I get Pentium at full speed, a 486DX2-66 at the next speed level (CCD), a 486DX-33 after that (L1D) and lastly a 386DX-25 (L1D+L2D). I could probably fine tune this even further by applying slower memory timings in the BIOS, downclocking the CPU to …

Ultima Online. I lost too many hours of my life to this over 20 years ago. I wonder if it's worth playing now. Lots of community run servers now, so I would guess some are fun and others are not. UO was never my thing, so I can't really judge. Maybe worth a look, though, if you were really into it …

Using cache tricks, a P1 can run a wide variety of older speed sensitive games as well. Not as nicely as a PMMX, mind you, but still a nice capability.

being forked from something is literally being based on it Nah, not necessarily. A little depends on meaning. BSD originally borrowed code from AT&T UNIX, but any vestigial relationship is long gone subsequent to the 1994 settlement between USL and BSDI. You can't really say it's AT&T UNIX based …

I probably wouldn't use a via as they're usually not as robust for soldering on. I think the two pin jumper pad by the corner mounting hole would work. 24 ga wire looks to be about right. If so, you can run a jumper wire along the board edge and tape it down.

Wow! Sorry for the newbie question, now, but what would be the best way to fix this particular problem? Best would be tracing what is being powered by that diode and running thicker wire between two points directly. Yes. Use the diode through hole on the right side of the picture as a solder point. …

Shorted transistor would conduct 5V straight to Vcore or Vcore to ground. There are also other scenarios but those are the two what would possibly generate short. I would do similar short check and measure resistance between [Vcore output <-> GND] and [Vcore output <-> 5V input]. Similar for caps. …
Re: 5IVXB Motherboard Difficulty flashing Bios

Why do not flash the new bios from the mainboard using uniflash? You wouldn't have any issue with 12 volt in that case. That would be a great option if the board could be made to boot which, AFAIU, is not currently possible due to the partially corrupted flash chip . Hot flashing in another board …
