Yeah, M1541 M1542 are similar and shared the same datasheet. From the picture, there is also an M1543 on the motherboard which does have a PMU. The M1543 reported itself in the device detection as 1533. I checked the M1543 datasheet and it's PMU should have a device id of 10B9:7101, which did not …

If i see it correctly, it's an M1542 A1. I guess the same applies there? BTW I updated the BIOS using info here: Bios Update, but how do I identify which one I got? not sure if that matters in this case.

Your problem might be similar to kikendo (see page 6), in that the ALi chipset was a very early version which has no throttle function (they are problematic because the chipsets were made during the very early days of ACPI, and the preliminary datasheet found on the internet doesn't match with the …

I tested it now with ACPI on, and while it does not give an error anymore and it does save the setting (if you run cpuspd a), it does not seem to have any impact. I set the throttle down to 1, it will then show its set to 1/8 on 3DBench V1.0 it has no impact. then to be sure I rebooted again, also …

The manual https://www.vogonsdrivers.com/getfile.php?fileid=674 states ACPI setting is in the "Power Management Setup" menu. The program mentiones that ACPI is disabled. Don't see any option in my BIOS. I am using an ASCORP 5ali61, in the manual it lists the AMD K6 III+ which was released in 2000. …

I have been experimenting further with the Slowdown tools and BIOS Settings (with a BUS of 66Mhz and a multiplier of 2). With also disabling the mainboard cache, Frame Buffer, A20 and setting the Dram Timing to Low I have been able to set the Speed as low as 3DBench 10, which is still too fast for …

I tried using the program but without much success. I am using a AMD K6 II+ 570Mhz, which for my tests was already booted in 66Mhz with External Cache Disabled. I also set the Multiplier to 2, and L1 as well as L2 were deactivated via setmul. The program mentiones that ACPI is disabled. Don't see …

I experimented a lot with my K6 II+ CPU which can do 2x66Mhz up to 6x600Mhz, with enabling and disabling cache. As mentioned in the opening post, there is quite a gap of what you can even do with cache disabling. Basically the Slowest you can get with L1 enabled is a 3D-Bench 1.0c score of 135,7, …

I am currently looking for some "best usecases" for downclocking a SS7 board, either manually or using one of the K6 II+ III+ CPUs, without disabling the cache. I looked into a lot of games already, but most often the lowest CPU Speed of 133Mhz or 166Mhz will not give a significant improvement as …

Here is Epos Vox latest video reviewing the RetroTink4K, and he actually tested it using DOS as well. Linked at the timestamp https://youtu.be/_KUxCUtSiI4?t=1584 he ran into issues with games constantly switching resolution, but says its possible most likely to automatically do that if you create a …
Lands of Lore 2 on 3dfx with mouse glitch
Posted on 2023-11-25, 19:20
Heyho, got another game which doesn't run properly on GLIDE on my Voodoo 3 within DOS (with some other games I already gave up) . Lands of Lore 2 is patched and does start, however when Hardware acceleration is active, and I move the mouse I get weird horizontal lines. Also my mouse is a bit floaty. …

Thanks, will check NOLFB! Yeah, both titles are also supporting 3DFX, but I also want to try to compare, and would like the better software version being available. Because otherwise the 3dfx version is obviously better. Especially with modern screens 3dfx often doesnt look too great and software …

BTW, the Voodoo3 doesn't support 15bpp video modes that some DOS games use. Not sure about Screamer 2 in software rendering though. The mode in screamer 2 is called "High Res 65k Colors". Would that be 15bpp? Or is that something completely different? The Low Res 65k Colors option shows the game, …

Have you tried running VESAFIX in conjunction with the modded drivers from Rob Muller? For Screamer 2 there is no univbe, so I dont think the modded driver thing applies there. vesafix -6 keeps the beautifully colored pic in my first post For GTA 1 the combination of both actually fixes the issue!

That sounds like an UniVBE message. Go to: https://gona.mactar.hu/DOS_TESTS/ Search for Rob Muller and try the modified univbe.drv files. Thanks you. I just tried it, but unfortunately it doesnt work. GTA 1 does use the UNIVBE 5.3a and so I put in the right file in the folder. The game doesnt give …
Voodoo 3 and Super VGA / UNIVBE / High Color Mode Issues
Posted on 2023-11-23, 12:52
Some games have "high color" modes, like GTA 1 and Screamer 2. I am not talking about the 3dfx modes but specifically the ones with high colors. Upon starting these with a Voodoo 3 in GTA I get a "No supported SuperVGA chip detected!". On Screamer 2 I get a broken screen instead. vcs 2023-11-23 at …

Ok, seems like I was a bit too quick here. Yes it works, but after playing a few minutes the sound deteriorates more and more. After a few minutes the sound of the motor is almost completely covered by crackling noises. This issue was also reported in this very old thread here: https://www.vogons. …
