Hey! i've got the opportunity to buy this Miro Crystal 40SV VLB, is it any good? Didn't find anything useful on the net... thanks!

ok thanks so you don't think there is something else seriously wrong? might try to replace the PSU sometime and might even recap the mainboard then..

that PSU is stable at 12.2V/5.11V. I now first installed everything (incl. NIC driver and TCP stack) and then configured the faster memory settings, so far everything is working. seems that the faster settings made problems during the NIC detection process, for whatever reason. still no idea if it …

Funny, as I was reading that I was going to say; Test your PSU if possible, assuming you have a multi-meter to do this with. If you do test it, do so whilst it is connected to the system and with the troublesome cards installed as otherwise you won't know what is happening to the voltages when the …

verified: the instability also occurs with the additional ISA card (NIC) installed. as soon as I go back to slow settings, everything works normal. Could this have something to do with "load" on the ISA bus?

thanks! as this is and will be the most powerful retro rig for me, i have no reason to choose another card than the x1950xt 😀
Re: Is this CRT Monitor Dying?
Posted on 2015-08-16, 17:08
whenever i had this issue it was related to too high resolution for the used vga cable (bad shielding, cable too long, ...). but as your issue persists even at low resolutions, i don't think that it would work better with another cable.

it is confirmed now. as long as any VLB I/O controller stays out of the system, everything is OK. I tried three different VLB controllers.. strange. edit: will verify that but it seems that it also gets unstable when I add another ISA card (to be precise, a NIC) to the system. it random freezes …
Re: Soyo 4SAW2 not working :(
Posted on 2015-08-16, 16:41
i think i already tried to remove the cache entirely - didn't change anything. I have tried the S3 Trio64 PCI, an old OAK OTI077 ISA card and two CL GD5426 VLB cards. HDD and FDD weren't connected (lose setup on the table for testing purposes). no corrosion on the SIMMs or the BIOS chip. I have …
Re: Speedsys 4.78 weird MHz
Posted on 2015-08-16, 16:31
thanks! I'll maybe open another thread later on how to swap to a 80MHz crystal on that board. someone here once wrote he had the exact same board but with a 80MHz crystal (it even has a place left for it)...
Re: which of these vlb cards for DX4-100?

I did go with the S3 805 for now (the jaton). the miro stays in the 5x86 until I replace it with a better one... thanks for your advices!
Speedsys 4.78 weird MHz
Posted on 2015-08-16, 15:39
Hi i have just upgraded my 386 build (Asus ISA 386-C, Am386DX-40) with a Cx486DLC @ 40MHz. The NPU (IIT 3C87-40) is still in place. From the CPU score (6.83) it looks good, but Speedsys shows only 11MHz - what's that supposed to mean? I have unfortunately a 66MHz crystal on that board so all the …
Soyo 025K2 486 stable only on slow RAM timings
Posted on 2015-08-16, 00:41
Hi my Soyo 025K2 seems only to run stable on nearly the slowest RAM settings. I have 60ns FPM 72 pin memory and 256KB of 15ns cache (with ASTER TAG RAM). I've already tried other memory modules (60ns and 70ns), all of them only work reliably with the attached settings. Any idea? Maybe an outdated, …

thank you, I've loaded a DOS driver and now it is faster!
ISA vs. VLB Multi I/O Controller
Posted on 2015-08-15, 22:46
Hi i always thought that quite any VLB Multi I/O Controller should be faster than an ISA Multi I/O controller, however in my 486 DX4-100 system I just found out that the VLB card is even a little bit slower in Speedsys HDD Fast test. Is this the wrong test, do I have to load some kind of driver or …

As a general rule, S3's were fast and compatible. The Miro I don't know anything about, so I'd wait for input on that first as it might be good. Edit: A quick Google search implies the Miro is another S3 805 but I could be wrong. thanks! yes, the Miro is another S3 805, cool thing :-) I can't …
Re: Soyo 4SAW2 not working :(

I tried an old S3 Trio64 - I also tried only to use one FPM stick. I don't have an external programmer, how do I hot-flash it? Is there some kind of guide somewhere what to be aware of, ...? thank you!

Hey! I managed to upgrade one of my DX2-66 with an Intel 5V DX4-100 Overdrive processor and now I'm looking for which of my VLB cards would be the best for that system. I have: - S3 805 1MB ( http://www.amoretro.de/2013/01/jaton-vl41cv2-s3-805-1mb-vesa-local-bus-vlb.html ) - miro Crystal 8S 1MB ( …
