Re: Configuring a PCChips 486 Motherboard with single banked cache

Alright everyone, Currently I have everything stable but some people were saying I'm losing performance and also asking to see pictures of my cache chips and if my RAM was EDO. I'm attaching my current chipset configuration as well as a picture of my cache chips and a picture of the 32 MB RAM stick …

PCChips M912 in order for the motherboard to actually see the cache correctly I figured out after poking around in the manual the chipset auto config fuction must be turned off, and the "Cache Read Hit Wait State" must be set to "3-2-2-2". Setting it to that makes the cache work correctly but now …

So I've been working on and playing with this 486 system I've actually posted about a couple times on this forum and its been pretty great. Upgraded to an AMD DX4 100MHz, with 32 MB of RAM on one 72 Pin SIMM, Tseng Labs ET4000 VLB, AWE64 Sound. Pretty good stuff, However when benchmarking it with a …

Just a quick update, My dad helped me figure this out because he had the same controller. For anyone else having this issue, JP 5 and JP 7 must be on in order to properly enable the Floppy controller. I have an IDE hard drive hooked up to it and working as well. Im going to try and get SCSI working …

Interesting. You would probably use this basically like a I/o card. In that you would put this in a motherboard that otherwise didn’t have any onboard fdd/ide/scsi ports Right, I got that part. I'm just scratching my head as to how to set the jumpers or any of that so the bios actually can see the …

Seems like to be an Adaptec 1520 / 1522 1) Does the SCSI controller include a floppy disk controller? 2) Do you have another floppy controller on or near your IDE controller? 3) If your SCSI controller have an unpopulated ROM socket, you need to boot either from floppy or IDE device. You just need …

I started building a 486 system, pretty bland, 486 DX2, 16 MB RAM, AWE 64, Tseng labs ET4000 VLB video card. I also got an Adaptec AIC-6360 disk controller. it has floppy scsi and ide plus parallel and serial on the back. But i havent been able to boot anything off of it. I noticed the bios chip …

Building a 486 VLB system

in Marvin \ General Old Hardware

I am looking to build a 486 VLB system and can't quite decide on a CPU, I'm torn between a Pentium overdrive 83, a 486 DX4 100, AMDs 5x86 or just a good old fashioned 486 dx2 66. Are there any drawbacks to the faster 486 class CPUs or a POD? and somewhat more importantly to me, how does the POD play …

You generally want Video BIOS caching Disabled at all times, as that does not speed anything up, and has a known history of causing weirdness and crashes when video BIOS caching is enabled. The regular BIOS shadow does a fine enough job of keeping the Video BIOS on the quick for most cards. Also …

Make sure the following are set accordingly (your BIOS may not have these options): Video BIOS caching set OFF. Turn off Byte Merge and/or Write Combine, if they are BIOS options. (Use the FASTVID speedup from Phil's Benchmark Suite to manually enable write combine for DOS games.) Some really janky …

If its a socket 7 VIA board the issue is likely not the card but the buggy and poor agp implementation on that chipset. The likely works fine on a BX or a intel board. If it was a PCI card it would likely give you no problems, on a VIA chipset like how voodoo 3s work fine becasue they lack the agp …

So, two different OS on same hardware give very different results. That means it's almost certainly driver related. Trying a completely different card (and VGA drivers) didn't help, so that's ruled out VGA as cause. One thing missing from specs: which chipset does this system have? Have the chipset …

S3 Savage should have a very compatible and fast 2D performance, and even decent 3D performance especially for those S3TC games. So the problem lies elswhere. Maybe driver or Direct X problems. i have tried a couple of different drivers with no luck i haven't tried reinstalling windows yet but i …

It used to have a Matrox Millennium graphics card with 2 MB of RAM and when i tried to run some newer (2D) games on it they ran like crap. Games like Civ 3 and Stronghold. So initially i chalked it up …
