I didnt know that there is 66mhz 387 fpu 😀 I used the next flags: cyrix.exe -e -i1 -i2 But i know that i didn't spend enough time on it, so there is ground to be covered for sure. Do you have a good formula about the flags ? It felt that it is a case by case thing. Thanks.

Yes, sxl2 can tick with 55mhz, but without FPU and RAM reduced to 4mb. These limitations combined with the overall instability of the system exceed my tolerance threshold 😁 Still, it is interesting to see how far we can roll with 386 class hardware.

The initial post suggest that the clock generators were swapped, but ics9150 is pin incompatible with 9250. Or do I read it wrong ?

@The Serpent Ride Agreed. Hi kixs, My retro interests are mostly within the 1990-1996 time period and around 2/3/4 x86 hardware. Some of my findings: https://www.petershipkov.com/temp/retro_pc_im … rks/vlb_pci.png it is from this post: Re: 3 (+3 more) retro battle stations

Great information. Thanks for taking the time to put it together. Here is my thinking about S3 968 and 486. On a 486 class machine, considering a decent video card, when it comes down to non-accelerated DOS graphics - performance is hard CPU bound. As a result we are largely stuck in VGA modes. The …

You have a point. Let me rephrase - s3 968 seems to 10% to 30% slower in DOS than many common video cards from that time period. Still, pretty ok in most cases for 486dx# class machine. Better ? 😁

The pci version is pretty good in windows (still quite slower than the mga), but is dismal in dos. Or at least thats what I see here. Is the view different from your tower ?

Re: How is the WDC graphic video card performance? WD90C11 and WD90C00

Both are mediocre. Not bad, not great. If you can get wd90c33 - thats another story. It is one of the best isa vga adapters.
Re: l2 cache compatibility rules

Yes, i am aware of that, thanks for clarifying it. The ISSI example was just one of many. I see similar UMC and WinBond incompatibility issues. About these 10ns ISSI chips - it is hard to prove if they are truly 10ns capable using up to 486 or early Pentium hardware. Clock speeds are not enough for …
Re: floppy drive "terminator"
Posted on 2020-08-10, 16:03
I have this pretty awesome EIDE VLB controller that has hardcoded logic to auto-detect floppy drives. This behavior cannot be disabled. So, if floppy drive is not connected, it takes a moment to think about it. Something that i would like to avoid. Hope it makes sense. Thanks for the link @wiretap. …

Checked briefly online, but couldn't find a convincing info. What will be the best way to "fool" a controller that floppy drive is attached to it ? Thanks.
l2 cache compatibility rules
Posted on 2020-08-10, 00:59
Are there any know rules about compatibility of 386 and 486 class L2 cache chips ? I usually go by trial and error to find working sets. Some UMC ones work with ISSI, others dont. Same for WinBond, EthronTech, Toshiba, etc. Often different series of the same brand are incompatible with each other. …
