I put the overdrive in, says its running at 66mhz on bootup, but sysinfo shows as dx4 75, so I guess that's the max this motherboard will run, also a score of 141 where a pentium 66 has just over 200

Thanx for your help yes I saw it on the second link through you then ended up on a different site for the same board, thanx for all your answers, ill try the overdrive see how it goes

I think I found it, looks like this one https://stason.org/TULARC/pc/motherboards/C/C … 86-33-50-L.html

Thanx for that I will study the links and material tonight when I get some time, from your knowledge do you think a intel overdrive chip could work in this board? I got a dx40dpr100 dx40dpr75 and dx20drp66

So I broke my 486/586 pci board few weeks ago trying to desolder a rtc chip and pulled out a old 486 board from my collection, last time I would of used this board was 13-15 years ago, but fired up just fine. Its running a 486dx50, isa only slots and I am trying to find info and possible manual/ …

Not sure, the scratch is the same color as the background, nothing shiny so didn't hurt to jump them, installed rtc and still no go, need a break from this. Going to put it aside for a while, perhaps tear it down and strart again. I always say it's a lesson to be learnt but I should of already …

Actually I haven't put the rtc back in, so that's next mission altho my hopes have been crushed already. Regarding the traces on the back, since every1 is having a good laugh ill give you more material, I was using a pin to try pry out hot solder from the back of the board like some1 mentioned on …

I tried jumping everything that looked sus to me, no luck got the 3 keyboard lights flash now but no post, need a break for a while form this board. Yeah I noticed I also sliced a row on traces on the back so jumped them all Could of all been avoided :( https://image.ibb.co/cmzocJ/IMG_20180706_ …

So I have/had a Biostar MB-8433UUD-A V3 with the soldered on rtc. I attempted to remove it and install a dip socket but the chip didn't come off clean and damaged tracks, I still installed the socket hoping for a miracle but now it doesn't post it all :( not even lights on keyboard when booting :( I …

Ok thanx i guess ill leave it as is, this pc is not plugged into the power when off so no current going through it

I have just finished doing a repair on 386 board after a leaked varta battery and it got me thiking if there is any danger of this on a Packard bell pb600. The Pb600 has a soldered on button cell 3v but also has a option for external 3.6v, the battery has not failed yet and system is working well …

Ok, I cleaned up the virus and installed m16abo-1 (v1.20).zip These must be the right drivers, volset.exe works, and able to successfully set volume level using /V: switch. Using P16ll drivers volset.exe would give me unable to detect card or something similar, so now everything is 100% thank you!

I couldn't find any fcc number, there is a number on top right on the picture of the back but Google had no hits

Actually it will be good to have software control over volume since my speakers don't have one built in, so the drivers will come in handy, thanx! I found I got a virus running in my boot sector called Lemming so this could be my problem why tie fighter crashes on sound detect and a few other games, …

Thanx for your help everybody, now I am getting sound in all the games so problem solved, this is a pure dos machine so thanx for the offer but don't need any further drivers

Thanx for your replies, I tried the P16II install, the utilities after installed would not recognize the card, however now dune2 does play digital sounds and music, I suspect this is after the installation added the set galaxy string along with my old set blaster string in autoexec.bat I could not …

So to start off I have a Packard bell legend which has the pb600 board, came with p75 and on board 256cache I have been slowly getting it up and running, upgraded it to a p133 and a cf card with a ide - > cf reader and everything else stock. Running dos 7.10 (no windows) I have been lurking these …
