Problems with sound

I noticed when i boot from Windows 95 to DOS i get error from EMM386 with smoething like:

EMM386 has detected error #

PC hangs and i need to turn it off.
First it did not bother me.  Problem was real when i booted with F8 option to DOS and had no sound. Wanted to see how well Quake 1 will run on this computer, but without sound its pointless.
To get sound working i needed EMM386 memory manager to work.
Every time sound driver was running DOS hang after running any program after that with above error by the memory manager.
So i had another PCI sound card. Downloaded DOS drivers and same problem. Replaced EMM385 and himem.sys with clean version, but problem remains. Used third PCI sound card, again same problem. No PCI sound card can run without EMM386 memory manager. At least with my sound cards.
Problems that my be the cause:

• Faulty main memory
• Wrong BIOS settings.

I still wanted to see how well Quake 1 will run. In Windows 95 with sound it has only 8MB free memory to use. It was really slow.

Final attempt. Used ISA ESS SoundDrive ES1868F sound card. Pulled this from another PC, installed and configured autoexec.bat

Quake 1 showed sound card and sound was there. It ran quite well. At least for 320x200 resolution.

Hardware configuration

Setting up this old PC is nothing special.
I used th99 archive to get spec for motherboard. But there are some differences as some markings and jumper locations are in different places.

I clocked CPU to 120MHz. It has 8KB of L1 cache.
Replaced L2 cache chips with UM61256AK-15. There are four 32K x 8 + one 32K x 8 as TAG. Total 128KB of L2 cache. Maximum can be 1MB, but i don't have chips. BIOS setting is WB.

First HDD all ready had Windows 95 code name Chicago installed. It is first version 4.00.950. See wikipedia.

I added second HDD from my collection FUJITSU MPB3032ATU.

Video card is PCI S3 Trio32/64 86C732 with 1MB of RAM.
Also PCI sound card Creative 5880. Not tested currently.
Motherboard has on free slot, witch can be filled with PCI USB board i have (VT6212L).

486 Computer

So i have computer with 486 CPU, 16 MB RAM.
I am planning to use Windows 95/Slackware Linux OS on this PC.
Also surfing on the web and doing some word processing and multimedia. Seems impossible with today's standards.

To be fair, i have all ready done some of these things. But its better to document all of this.
