Just wanted to contribute to this thread since I got so much help on my own M919 thread: https://www.vogons.org/viewtopic.php?f=46&t=73703 My cache module is a 02S5, and it came with an Amptron DX9700. The theory that the "5" means that the module is okay for 5v may still be correct, but there was a …

I transferred the CF HDD from another 486 to this board. I used the "Auto IDE" function on the main BIOS page, and it detected it correctly. Then I ran CACHECHK and SPEEDSYS (sorry for the bad photo -- didn't want to mess with the PCX file), and everything seems okay. I don't really know what all …

This almost never happens upon first boot-up, but it seems like things are working as they should before I add the HDD. I realize that I'll need to use a program to test the cache because the report of 256KB on boot isn't reliable. I've never seen a GUI-like BIOS on a 486 board. IMG_9473.jpg IMG_ …

I'm going to stick this heatsink/fan combo onto the 486DX4. The fan has a two-pin power connector. Ideally, I'd like to use a 2-pin to Molex adapter, but I don't have one of those. IMG_9470.jpg The M919 does have a fan connector. I'm sorry if this is an obvious question, but connecting the fan is as …

Thank you, I saw a bunch of sound blasters ISOs on archive.org but couldn't tell which one was for what card. No problem. Let me know if it works.

The km44c1000cj-6 chips in top pic should be 1Mx4, 60nS FPM. 8 chips = 4Mb SIMMS (8x1Mx4 /8), if double sided would be 8Mb SIMMS. The gm71c17403cj6 chips in bottom pic should be 4M x 4bit 60nS EDO. 8 chips = 16Mb SIMMS or 32MB if double sided Thank you! I look at the datasheets but then get …

About ready to test this thing, but I need some help with memory. I have a bag of mismatched 72-pin SIMMs and have always been bad at deciphering the markings on the chip to determine their size. I sorted them by type (FPM or EDO), speed, and whether there were chips on both sides. I ended up with …

Hello all. I recently got a Sound Blasters Live! CT4870 card to put in my Windows 98 computer. I found some newer drivers that were supposed to work I think from this site. I had the card installed and installed the drivers but it would have an error at the end of installation. After restart it …

The fake cache boards were soldered cache. Being that is a COAST it should be real. One thing: It says 3v so you must use a 3.3v 486, not a 5v as the cache is powered off the cpu VRMS and at 5v you would burn up the cache chips over time --- Unless they are 5v tolerant. Here is a topic here at …

Thanks. Glad to know that the modules didn't have fake chips on it. Will probably be able to test tomorrow. I think this board is actually an Amptron DX-9700, which would explain the sticker on the back of the module. The box also has a logo that's a big "A."

So I thought I was buying another Socket 3 VLB/PCI board not unlike an excellent board I own with an SiS chipset. It is NOS and came with original box, manual, and cables. I remember reading about 486 boards with fake cache but didn't put two and two together until the board arrived. It looks really …

A little bit of a necropost just to say how wild this board is. I got mine in a lot with some other LGA 775 boards without even knowing it was in there. It's a Rev 3.0 too.

The Viva Multimedia Maestro 16 VR box states 32 voices for the synthesizer. The Prometheus Aria 16 doesn't specifically state that but it compares it to a SB 16 and a PAS 16 saying that it supports 32 voices while the other 2 support only 20.. referring to the OPL3. 32 sounds right. I'll go with …
