You don't need the W98 disk. What you need is a disk with the
driver software.
Here is a site where you can download this driver software
http://www.modem-drivers.com/companies/24.htm

Note this a combination sound card - modem card.

You might also look on your C drive for a folder with a copy of the W98 CD.
The files in this folder will look like Win98xx.cab, where xx are numbers
from 01 through the 60's.
Start looking by looking for a folder C:\windows\Options\cabs as this is the
most common place for pre-installed windows disks to be copied.

I haven't used a computer for awhile, had it unplugged.
Went to set it up for son to use for games and it said it
discovered new hardware! AC 5618 sound modem or
something like that and to reinstall the driver. I

microsoft for download, can't figure out what I
need...son is driving me crazy, wants to play games, but
no fun with no sound...any suggestions? thank you
