ESS1688 - To PnP or not to PnP?

I have a ESS1688 card, the MPB-000036 variant like here: https://dosdays.co.uk/topics/images/kwx-sc1650.jpg It has ES1688F and ES968F chipsets. It does not have any jumpers set in any of its headers. Now everyone says that the ESS1688 is not Plug and Play, but my card gets detected as a Plug and …

So now I am using this motherboard with CWT200 AT PSU and...everything seems to be working fine, I was using an ATX PSU before. Could a PSU really cause such an issue? Maybe motherboard fixed itself, some solder joints, capacitor or something? The previously mentioned diode seem to be actually fine …

The cooler barely gets warm, even after prolonged usage, I am not worrying about the temperatures. :) I have found FIVE (!) other examples of K6-2's with the "MPM" datecode from Allegro Polish website: https://a.allegroimg.com/original/11aa27/0156778e4f80961787246eb8c665/Procesor-AMD-K6-2-350AFR-350 …

I've yet to throroughly test both systems, though I have noticed that the IDE speeds on the ALi Aladdin V are not that great, and can't enable DMA under 98SE. I know about the MK8330 modern ISA card, its website is the easiest way to download drivers for that chip 😀

The K6-2 450MHz I bought that I mentioned in my previous topic: https://www.vogons.org/viewtopic.php?f=46&t=91012 has only three letters "MPM" after the datecode, whereas most of K6's have four letters: https://cdn.discordapp.com/attachments/641260997017075732/1042169121409880084/IMG_20221115_202657 …

22kHz vs 44kHz sound effects difference sound (ha!) like a minor tradeback for me for having good DOS compatibility from a reasonably priced ISA card. The K6-2 450MHz arrived and it's working fine, alongside the S7AX motherboard, the BIOS settings are being saved thankfully on it. Will spend some …

Interesting to see all this discussion about the K6-III architecture and how there is real-life proof that it really had quite a short shelf life once Slot A/Socket A came to the market. As for my family's first PC, forgot to mention that it had an Award BIOS...though that is probably not helping …

Considering the CRT that I also got recently - LG StudioWorks 520Si - that works best at 800x600x85Hz (1024x768x60Hz is too small and too headache inducing for me), anything that can work at that resolution is enough for me. :) Maybe that ESS card will make sound with music work in Ganja Farmer, for …

Thank you all for your feedback, I'll have fun with whatever hardware I receive. I wasn't even thinking about a possibility of receiving two Baby AT PCs this year for free so I am somewhat happy. :) I actually met a person locally who is into retro stuff too, and is happy to grab some of my stuff …

Great summary mkarcher, thanks. So it is a good thing I haven't paid more for a 500MHz one, 450MHz should be enough. It is a learning experience for me to actually experience some proper retro hardware, rather than just relying on emulation or using more modern, non-retro stuff (USB booting, SATA, …

Eh, it's not that bad, it works fine. Still haven't figured out why the CMOS settings on it are not saved which I've described in another topic of mine, can't say for certain if it's the diode, capacitors or something else. Seems I am like 15 years too late for being excited about more period- …

The best cheap K6-2 I found and bought is a 450MHz one. Will be interesting to see how it compares to the Celeron 333 Slot 1 that I also have on that PCChips motherboard, the Celeron should be better, right? EDIT: How about overclocking on both of those?

From what I've read, 400-500MHz K6-2's should be based on the same Chomper Extended (CXT) core. If K6-III(+)'s/K6-2+'s were available here at a reasonable price, this of course would be a no brainer. It seems most people only think of the L2 Cache equipped Super Socket 7 CPU's, completly …

I can confirm that on my new PC with Intel Core i3-12100F and MSI PRO H610M-B DDR4 motherboard with the latest UEFI version (1.70), I am experiencing the same VCACHE Protection Error (needed to use HIMEMX to get to that stage). I could have tried older UEFI versions but do not want to risk my new …

I've tested the battery holder and it outputs stable 3V all the time so it's not the issue. There are no signs of corrosion or any issues with it. I've re-tested the diode next to it and it measures high resistance in both directions, so I assume replacing it would fix the issue?

I've tried cleaning the battery contacts with Isopropyl alcohol, …

Try creating a smaller partition, something like 10GB, do not use the whole drive. You can also try obtaining a 64GB or smaller drive, seems your laptop doesn't like larger drives.
