Maybe. Here is my speedsys from my 486-120 on my 496/497 PCI board. The cache speed is close but the memory is much faster. http://www.vogons.org/download/file.php?id=14313 That's indeed by far faster - but I honestly don't know what I could do to increase memory performance on my system (if it is …

Hi after my first attempt to build a 486DX4 which wasn't too successful because of defective hardware I've managed to get a whole computer which was declared as 486DX4-100 but in fact turned out to be a Am5x86-133. It was rather cheap so I decided to buy the box without knowing the exact content. …

Thanks for all your advices and help! My conclusion after some hours of testing and playing around is that the mainboard somehow has to be faulty because sometimes (mostly not) serial and parallel ports get detected during POST when using the Winbond VLB I/O controller, in another (very similar) …

I never heard any VLB controllers with two IDE channels and not supporting CD drives. Even my 25 five year old single channel ISA IDE controllers can do that. Are you sure you adjusted master/slave jumpers accordingly? I also suggest booting up your system with a standard windows 98 startup floppy. …

Hi i've now put the memory from one VLB card to the other one and now it seems to be working, no more lockups or fragments (the cards are nearly identical). Additionally, I used the second VLB slot for graphics now, not the third slot. So maybe the third slot is damaged somehow (due to mainboard …

- If your VLB controller have its own BIOS supporting big drives (an EIDE controller?), then, no, AFAIK your motherboard BIOS does not need to be supporting drives bigger than 528 (504)MB. - Those kind of artifacts might be related to defective RAM on board the video cards. If they are socketed, I …

What type of DX4 CPU do you have? Write back or write through? Your motherboard might only support the latter. Same with HDD capacity. Some older controllers were limited to 2.1 GB. thanks for you reply, how do i find out which one it is? also: is hdd capacity limit a matter of i/o controller, of …

Hi currently I'm trying to build a 486 DX4 based on Soyo 25J/K/L. I have two issues at the moment: - max. disk size seems to be about 500MB - is that due to the mainboard BIOS or due to the Winbond I/O controller or do both devices have to support drives larger 500MB? - weird characters during boot …

I have a PC Chips M919 v3.4 that takes that module, currently running without cache. I had resigned myself to run without cache since the only one I found online was that eBay auction for $150. Let me know if you decide to sell it. I posted about it a while ago: http://www.vogons.org/viewtopic.php …

Hi as far as I know, the AMD 386DX CPUs were exact copies of the Intel CPUs. So I swapped out the Intel 386DX-33 in my 386 box with an AMD 386DX-40 and added an iit 4C87DLC-40 coprocessor to get the best performance possible. I've enabled the coprocessor in the BIOS and I set the jumper "sync/async …
