Boot System Error

Sounds like your audio drivers and software need to be re-installed. Make sure what exact audio card you have installed in your CPU. Look for drivers that came with your system and try re-installing them. If this doesn't work right away, you will need to play around a bit. You may need to fully uninstall your sound card and audio software. If there is extra audio programs installed, you can probably just uninstall them from the Add\Remove applet in the Control Panel and leave the sound card alone. Some sound cards install extraneous programs for audio mixing that aren't necessary if you have Windows Media Player or Real Player and such. If the drivers provided do not work, you will need to go to the manufacturer's site to download updated drivers for your operating system. Also, check some free driver sites for updated drivers--

Hope this helps.

First, do you need DOS mode audio support?
The line in config.sys is for dos support.

It was a number of months ago, but what I had to do to take care of the same problem was to relocate the files that the ESS audio driver was using to re-createthe config.sys entry.

I think that I also performed a registry edit to finish this disableing.
CAUTION!!! regedit can disable your system if you are not careful.

If like many sound cards, there is no mfg identified, you can try the reference drivers from ESS Technology www.esstech.com
Just make sure that you get the correct drivers for your OS and ess chipset on the card.

Though other posted answers will solve yopur problem, you may try to locate the ESAUDIO.SYS/EXE (check extension) on your drive and give correct path in this line by editing the CONFIG.SYS file. It should work as the installation of sound card software may be OK as it reenables its DOS mode drivers. You may do it by running SYSEDIT command or by editing the file directly with EDIT in windows or DOS prompt.

Also check if there is any line in AUTOEXEC.BAT or CONFIG.SYS which initiates check for this line to be present in Config.sys.

Be careful - Disabling this driver may leave your card non working as many card need initialisation before being used by Windows drivers.

Best of Luck.
