I did not manage to get it work with doom, and decided to go with my yamaha ymf719e based labway lwha151a00. I read this card has overall very good soundblaster compatibility. Regarding the built in synthesizer... Yeah I know that, but nothing beats the original 😉

I checked the settings again I cannot see anything wrong... any ideas?

Hi guys, after finally having all the peaces for my 486 Dx2 together I fiannly wanted to play DOOM on it. Everything works fine except the Game FX sound. I can select Sound Canvas and my Roland SC-88VL works just fine. However I do not get any FX sound for shooting etc. I replaced the Maestro 32/96 …

So I finally got a eprom programmer and burned a new chip. The computer boots up perfectly and now also shows the proper CPU speed all the time 😀 Next is to get a AMD 5x86 to work with the board - just need find the proper jumper settings anywhere.

Ok, I just found a guy on ebay who was selling the chips I need for 1MB from another 486 mainboard. The TAG ram, can I simply use the same chip like the other 8 chips or is it anything special?

Thanks. I figured out the jumpers for the LED displays. Now it shows LO and HI. However with the cache I have not been succesfull so far. Do you know specific chip models/names?

Ok, I think I resolved the issue... I started NSSI, which properly recognized the CPU. When I did the benchmark the CPU performed slightly worse then a DX-33. When I realized this is a real-time benchmark, I thought I'll try connecting the turbo switch to see whether there is going to be a change. …

I already tried using the bios from the other board. Only after doing that the motherboard began to boot up properly. After putting the original bios back in, the motherboard kept booting up properly. The only issue left as far as I can see is the wrong CPU speed...

Ok, I'll do a benchmark and check the result. To be honest, I do not think it is the bios version since the processor was already out on the market before the bios. Also I have a SVGOX4 rev. 1.5, which I believe is an earlier revision of the SV2GX4? It has the same bios version and shows the correct …

I have the bios version 0302. I just checked the jumper settings again according to the files you provided. No matter how I set the jumpers, my i486 DX2 66 is always recognized as a Dx2 with 32 Mhz. Any ideas?

I see that but as jesolo mentioned, maybe the jumper settings changed and I am setting the jumpers based on another bios revision? Though this seems unlikely, at the moment I do not have any other idea what might cause show the wrong CPU speed. Any suggestions?

Thank you guys! I just ordered the parts. The only issue left is that the bootup screen shows the wrong CPU speed with the two CPU types I have. I hope this simply a jumper mistake and changes with the bios update.

I see... do you know an eprom reader you can recommend and how big does the eprom need to be?

Somehow I managed to boot the motherboard up properly. I took all the chips and tried chips from other boards and now it boots up. The only issue I now have is that I cannot update the bios. The flashtool tells me that the bios is write protected. Is there any way to disable the protection and flash …

Thank you for the quick reply. I have already done that: 1) The manual is the correct one 2) I replaced the battery 3) I replaced the cache 4) I can only see one capacitor on the motherboard and it seems to be ok. Any other ideas?

Hi guys, I just found this asus motherboard in an old storage and somehow cannot get it to work. Maybe one of you has an idea what could be wrong? So I have installed an Intel i486 DX2 66 Mhz and set the jumpers according to the manual I found on phils homepage. When I try to boot it up most of the …
