Continuing on my luck of finding an "arcade" V3 3000, I lucked out on some sweet upgrades for less than what they usually go for: PIII-S-SL5XL.jpg PC133-CL2.jpg AU8330.jpg I'm going to stop now while I'm still ahead! I've never used an Aureal Vortex 2 before. I have a lot of questions: What features …

Now I'm confused. Thought this was going to be a 55 based comparison. Which to me means only devices with official GS support. SC-7 was never meant to be a 55. E-Mu Sound Engine is a Waveblaster... I think including such extras kind of defeats the point imo. Sorry, I might have skipped through the …

AFAIR, the market share of Web Servers in 1994 - 1995 were as follows: 1994: 1. NCSA HTTPD on UNIX/BSD 2. Netscape Web Server on UNIX/BSD 1995: 1. NCSA HTTPD on UNIX/BSD 2. Apache HTTPD on UNIX/BSD 3. Netscape Web Server on UNIX/BSD 4. IIS on WINNT

Woo Hoo! Managed to successfully change the FSB on the VIA based MSI MS-6368 motherboard in DOS using the utility I just wrote! Too bad the motherboard is only stable at +- 10 FSB MHz, but it actually works! Once more, huge thanks to @EduBat for all his help decoding the PLL datasheet . 20220311_ …

The datasheet shows that the values of the "latched FSx#" can be seen in bytes 1, 3 and 4. Reading from your dump we have FS0# - 0, FS1# - 0, FS2# - 0, FS3# - 1 then note 2 on page 6 says "Latched Frequency Selects (FS#) will be inverted logic load of the input frequency select pin conditions" …

Can't tell from the datasheet, but maybe the frequency set by the power on latched inputs isn't shown in bits 7:4,2. So when bit 3 is set to '0' then the values you read for 7:4,2 don't tell you what the current frequency is. They just tell you what the frequency will be if you set bit 3 to '1'. …

Could it be that the board implements digital IO for selecting the fsb instead of choosing it via i2c? Hmm, I hadn't even heard of digital IO before! But I highly doubt that my MS-6368 motherboard from 2003, manufactured by MSI, and using VIA chipsets, has anything as fancy named as digital IO in …

Hey, nice! Good to know there's a bit of a workaround.😃👍 Awesome, good result. Thanks, just want to point out that it's not the VGA boost function that is actually reducing the noise. The boost function, and the input and output impedance matching merely seem to make the dim Voodoo1 signal brighter …

From what I've read, the 10-pin USB header preceded the 9-pin USB header, which later became the standard. I faced a similar issue with my QDI A10T board as it only had the 10-pin USB header. I used breakout cables to connect from the 9-pin connector to the 10-pin header. You would need to map the …

I'm with pentiumspeed here. You probably need to prevent the noise from getting into the output signal in the first place. I'm sorry if there was a misunderstanding because I can't express myself precisely: There is not a general incompatibility between your screen and the card. I just assume that …

The diagonal lines is a noise that gotten into the video signal on the card. You need to modify the card through. Cheers, Yes, but what if @Doornkaat is right and it is due to some incompatibility between the Voodoo and the scaler in the TFT, then if I can eliminate the incompatibility I can …
