I you don't specify a CONFIG.SYS, Windows will load some default settings.

[vcache] settings you mentioned in SYSTEM.INI should give more stable results. Adding MinTimeSlice=80 under [386Enh] can help too, or another value above 20 and max 120.

SMARTDRV /X /L /V /B:57344 will speed up your system (in AUTOEXEC.BAT).

I can't help you with your graphics card. Try VBEMP to rule out graphics driver problems.

i can't fix the problem
i need ask: i need 1st update the system with SP3 or AutoPatch, before install the driver?
share me your dll, maybe i can get more luck

Did you try VBEMP to rule-out graphics card driver problems?

HDA2.DLL is a driver made by 'Watler' for Win3x !!!! Use on Windows 9x is FULLY experimental. But your system MUST be  stable before trying HDA2.DLL.  

Updating Windows 98SE makes no sense, start with a basic SETUP /p i installation and VBEMP as graphics driver. Further 98KRNLUP.EXE KRNLUP98, BHDD31.ZIP, RLOEW's two disk patches (for IDE and SATA) and his memory patch, if needed with the /M switch.

BTW: link to HDA2.DLL's in HDADRV9L.zip and HDADRV9J.zip on my Google-Drive: https://drive.google.com/drive/folders/1kvmrcmZbnkNm8Y2z3uyPHNKjxNR70MVM?usp=drive_link

Be aware HDAICOUT.HDA in the zip's are Watler's examples, not my version(s)!

HDADRV9L.zip is same as the current version on Watlers site: http://turkeys4me.byethost4.com/programs/?i=1

"Did you try VBEMP to rule-out graphics card driver problems?"
i reinstall the Windows 98SE, but i get errors when i try install it.. don't let me, even on hard way(searching manually)

1 st - for use the VBEMP must be Universal... manual version for install it.... after format and reinstall the Windows and AutoPacher updates..

thanks for all

system error message: "runtime error 202 at 0003:020E"
the desktop is showed !!!

This error is thrown by HDA2.DLL.

What value of MinTimeSlice was in use in SYSTEM.INI?

hum.. more than 80

That's already high. The highest value I ever used is MinTimeSlice=120

Currently I am working at a project to run Windows 98SE on a 64-bits ram-drive. I get only stable results with double buffering.

Maybe you can try with the line

DoubleBuffer=2 in MSDOS.SYS under [options]

now i will format on normal way and not faster.. then i will try again...
correct me: the DirectX 9 is a requisite?

I use DirectX 9.0c all the time, but I am not sure about the difference without (so version that comes with Windows 98SE CD-rom, I believe version 6.0 or 6.1 ??). Lately I tried HDA2.DLL before installing DirectX 9.0c, but I quickly installed it because I needed the mp3-codec inside.     

honestly.. i tried several times without success

Sorry to hear that. Your system seems to be a bad fit with HDA2.DLL. I have no new ideas.

thanks for all... thank you

i found the 'HDABUS98.INF' and it's found by manual search... but i get 1  message when copying files: "the file 'hdaudbus.sys' was not found.. Windows needs the disk labeled "Microsoft UAA Bus Driver for High Definition Audio Instalation Disk #1" to continue....."
anyone can help find the file?
