hello all, just wondering if anyone here has ever seen this issue before. i've got this 486 board that keeps resetting itself and spitting out the same beep code nonstop. i guess something has failed or has gone intermittent, but i'm not sure where to start, since i've never seen this problem before …

Intel D850GB (their original Pentium 4 board, and the only one they made for Socket 423) has a soldered PC/PCI header.

thanks. the same exact thing just happened to me. it's unsettling that installing an ordinary game would clobber Windows in such a way. i suspect it's something to do with sound, because the installer says it's installing a "sound driver" along with the game. (uh...what?) must be some kind of weird …

re: MR-BIOS, i have mixed feelings about it too. i am blown away that anyone even bothered to make such a BIOS in 1994, but yeah, it's got its own shortcomings. i suspect that it really was intended for actual, original IBM AT motherboards, or clone boards built the same way (i.e. with a fully …

I'm slowly running out of ideas, perhaps I have a faulty mobo chip. I'm going to rotate RAM chips, just in case, but I don't think it's RAM since I once got the 3DBench test running happily but the keyboard hanged. sorry about the cosmetic damage to your board. don't beat yourself up over it. it is …

crossposting from the main 286 BIOS thread... here's yet another Award BIOS. interesting how these old Suntac boards all look nearly the same, and yet each one has its own bespoke BIOS. this is Award version 3.03HL, but it's twice as large as the version already dumped (64k instead of 32k, and it's …

#68 my Suntac-based board, similar to #61 and probably by the same generic manufacturer. jdupes says my BIOS does not match anything in predator99's archive, so i am posting it here. there is a version "3.03HL" already posted but my version is 64k instead of 32k. EDIT: the BIOS does indeed match v3. …

nice work on the latest update. i really have to say though, i am uneasy with the "Self Noise" column and how it's purely based on the DAC. it's uncomfortably close to those endless arguments in audiophile forums comparing two CD players, one with 64x oversampling DACs, and the other with 128x …

how do I know what those appropriate values are when the capacitors have no markings apart from polarity, capacitance and voltage that is all the information you need when replacing capacitors. they certainly DO NOT need to be the same part, or from the same series, or from the same manufacturer. …

nice. i've got a CT2760 here that i'll mod according to your diagrams. protip for anyone doing the same: recap the card too. you will be amazed how much recapping an old sound card helps quiet it down. the older the card, the better. my CT1350B went from being pretty much unusable, to being an …

interesting, my ALS007 worked just fine with DOTT yes, MAYBE i have an ALS007 somewhere? one thing is for sure, the ALS007 is definitely not the same chip as the ALS100 with a different marking; the Windows drivers have different INF files: 5118 05-15-96 17:41 ALS007.INF 5069 05-15-96 17:36 ALS100. …

the ALS100 has full SB16 compatibility. yes, and i went to the trouble of seeking one out for this reason, but the chipset is... flaky. be careful. Day of the Tentacle gave me bizarre, completely wrong FM music. Jill of the Jungle does not even recognize the card at all. (i did not test with …

@zoinknoise: It's a nice hint that i gladly included down in the explanation of the Bug. According to Mobygamer Tie Fighter also supports AWE32 for music. Do you know if that is correct? hmmmmm not much experience with that game, but AWE32 support is definitely listed on the box: https://www. …

nice chart, though i would *personally* add one bit of info. it mentions how the entire AWE32 and SB32 series has that Duke3D slowdown weirdness with external MIDI music, inherited from the SB16 series. this is true, but remember that Duke3D *does* have native AWE32 support, and therefore it IS …
