I am please to report that I have finally finished my 486 build. This was inspired by LGR's video that he posted back in July https://www.youtube.com/watch?v=fbjYkPKRm-8 . It took me until now to gather the parts necessary and then figure out how to put it together. I am using the same motherboard as LGR as that seemed like a great choice. I ended up putting a DX4 100 overdrive and a GoTek Floppy Emulator in it as well. I initially wasted a lot of time trying to get an old ATX case to work with it but eventually caved and got an AT case from eBay. I am very happy with the case it almost looks new. Anyway, I have posted a few threads on here since starting this endeavour and I appreciate all the help that I received. I realize some of me questions were really noob! Here are a few pictures:

Looks great man! I like the case as well it has that nice retro flair too it. Looks like it has decent cable management too considering that wasn't a real concern back then. Congrats again on getting your build together it looks really nice.

Nice! That board has a pretty good chipset for the 486 era, I think a DX4 fits like a glove! More importantly, no barrel or Dallas RTC junk! I have that same board and I'm planning a build around it in the following weeks/months if I can find enough free time.

I see you have a CPU fan there, was the DX4 overdrive running too hot? Because I believe those came with heatsink only, no fan.

Also, I really like the case, did the cool 486 badge come with it or you got it separately?

Those Enlight cases are really sharp, and have a nice build quality to them. The removable motherboard tray and tool-less bezel are a nice added touch too.

My P233 build has the same case with a Myoda badge (local computer dealer which is somehow still in operation with an appropriately gaudy website.) I wish I could find another, it's a tiny little beast and very easy to work with.

The case badge I got from eBay. I put the fan on the overdrive just because I could really. There is also a case fan at the front. Not really necessary but maybe it will help this old hardware last longer. I am a sucker for cable management, it is an obsession of mine!

I'm confused
The Pic shows a HDD, you running both a HDD and SD?
You also say your running on board ESS 688, but the pic shows a Sound card, or is that the ESS?

Nice system either way. I'm no purest and also like having the mix of new (gotek/SD's) with old 486's

So it is! a Compaq Presario CDS 520 by chance? (I just saw 486... and read down from there)
So what's the full spec of this PC?

The spec of the new one is as follows:

16MB 72-pin SIMM RAM (2x8MB)
1MB Diamond Speedstar Pro VLB video card
AOpen VI15G Socket 3 Motherboard
HDD/FDD VLB controller card
486 DX4-100 (Overdrive)
Soundblaster 16 Value CT2770
HDD is some random IDE drive made within the last 10 years (can't remember)

It is the same motherboard and video card that LGR used in his build here: https://www.youtube.com/watch?v=fbjYkPKRm-8

His video was my original inspiration.

Well it's been over 6 months since I put this together. I have not had a good chance to enjoy it much yet due to moving and being busy with work. As I have a serial to PS/2 adapter coming soon I thought I would try and figure out the issue with the Soundblaster 16 CT2770 I am having. The volume is really low in all games. The volume is OK in the diagnose utility. When I run the SB16SET.EXE command it comes back with "MIX0014: Low level driver error". Anybody know what that means?

I used the CT2770 with similar settings in an XT 8088 machine, except in that case used H1 T3 due to lack of 16 bit ISA slot, try the above and
see how you go.

I used to have a Vi15G motherboard. Not sure why the hell I got rid of it.

I will try this when I get home. I see you REM'd a couple of lines in there. I know I have the one with DIAGNOSE in it, not sure about the SBFMDRV one. But as they are removed that should be OK anyway. If it doesn't work I will post my startup files.

I tried following your instructions and got the same error while the startup files were being processed. It doesn't help that I have not worked on this for about 6 months. See my AUTOEXEC.BAT and CONFIG.SYS below, maybe you can figure out what I am doing wrong:

Issues with an AWE32?

There's a newer(other) mixerset you can download that might fix your problem.

I will give it a try. I do have another sound card, a Sound Blaster AWE32 CT3780 ISA. If I keep having problems with this SB16 I will switch to that.
