Re: In an SMP system how does DOS/98 choose the CPU to utilise?

Hmm every single one I used: SoftFSB, CPUZ, CPUCool etc. Well now I place your tool higher then theirs :) At a guess CPUZ get's it right for Coppermine, but not Cascades. You could try reporting the bug to the CPUZ thread and see if Franck fixes it. I wonder if I could use SIV with an LCD from …

Does the system have a thirsty AGP GPU and PCI-X cards? The TYAN S2466 (Tiger MPX) is not in a case and I can't remember which GPUs I used back then, I suspect GPU-0 was a GeForce FX 5200 [NV34]. There were no PCI-X cards. All hardware reading apps get confused when the multi is set low when …

The Gigabyte looks well featured for a 650W one too, especially the monitoring. The only thing I would say is with a dual PIII, adding a FX5900 Ultra and several drives might push the 3.3v/5v rails. A dual K7 system definately would. Yes, as the Thermaltake SPG-0650D-G is only good for 20A @ +5, …

The GPIOs do not toggle in the way i expect. On the first click the hex values under current values change and i/o changes to GPU output - depends on GPIO Thank you for trying. I checked what happened on my MCH 840 + ICH1 system and noticed there was a bug so I have fixed it in that attached SIV32X …

Awaiting a new PSU, I'll post results when I get it. (Borrowed my daily driver Nipron one for these tests that I need back. I no longer trust the Enermax PSUs I bought for my retro systems sadly.) OK, which PSU are you getting? The only Enermax PSU I have is a DigiFanless which seems OK to me, is …

I don't mind trying that, but am unsure of the approach I need to take. You need to toggle them one at a time, if you toggle them all chances are the system will just lockup, reboot or similar. What I would do is: 1 ) Start a SIV and look at what [SMB Bus] reports 2 ) Start another by doing SIV32X …

I never found a solution to the CPU-1 cache being disabled so felt I would bump this thread and hope. Below you can see I also get the issue on WXP.

No SPD data from any app. But HWINFO and SIV report capacities correctly. Thank you checking out the test SIV and the datasheets. Looking in the OR840 Product Guide at Table 24 on page 86 then the Partition column confirms there is an SMBus multiplexor, but I can't see any information on how to …

Do you have a spreadsheet of CPU benchmark results or know the ballpark figures for a 386DX and 486 33/40? Thank you for checking out SIV V5.53 BIOS-01, all now looks OK to me. I don't have a spreadsheet, but looking in save files I have. I don't have an SMP 386 or 486 :( Intel 386 Model 0 39MHz …

All hardware reading apps get confused when the multi is set low when reporting the FSB and RAM speeds. (I had to rename to dmi.txt to upload) Thank you and the x11 rather than x3 was a bugette in SIV. With >= stepping 3 the rules change, my code was correct for Coppermine (Model 0x08), but not …

As you've guessed there are no temperature or voltage readouts. I haven't got any fans plugged in at the moment, so none should show up. Thank you and yes, you need to make a few more posts before you can send PMs, but I can't remember how many. When I looked at Menu->System->SMB Bus there are a …

I thought Windows dropped support for 5.25” drives with some version but I’m not sure. I just checked my Gigabyte 965P-DS3 and the BIOS allows a 1.2 MB 5.25" floppy to be selected, further Windows 10 20H1 Build 19041 seems to support it, but as I don't physically have a 5.25" drive I can't check if …

I can get the dmi file next run no problem, CPUZ had the same issue so it may just be the obscure motherboard. OK, I have just uploaded SIV 5.53 Beta-00 which should do better as once I looked at the save file I was able to improve the SIO reporting so please use this to generate new save files. …

I wonder if P4 xeons will work like this? I have a PC-DL i need to test before I box it up for storage... I suspect no. My Compaq Workstation W8000 won't post with a Intel Xeon MP (Gallatin) 2.70GHz SL79Z + Xeon MP (Gallatin) 3.00 GHz SL79V, but your mileage may vary. At the moment it's got 2 x …

@red-ray your program seemed to handle the mismatch fine. Had to use W2K due to the above issue at the moment. Thank you and W2K is fine. As you said SIV got the speeds correct and [CPU Benchmark] showed CPU-1 is appropriately faster than CPU-0. SIV came up with To be To be Filled as the …

By the time there were multi-core CPUs that could change speed it became clear that an invariant TSC (TSCIV) was needed so the TSC speed does not change as the CPU speed changes. There were probably a few multi-core CPUs that did not have TSCIV, but this is not relevant to running SMP P2/P3 systems …
