|It was probably put together by a local shop and has a brand name motherboard in it. The motherboard model may show on the posting screen when you first turn it on. Otherwise open the case and examine the motherboard for identifying info. You should probably check the hard drive model number too.|
Then you need to go to the support site for the motherboard and see if 98 drivers are available. If not, installing 98 on it is not advisable. But unless you (or your son) has a specific reason for wanting 98 on it you're better off with at least XP anyway.
Post back the motherboard and hard drive info if you need further help.
