cancelling a NTFS system

I had a 40 gig hard drive that had windows 2000 on it and I have reformated the drive to the manufacturer’s specs.

I am trying to install Win 98 on the drive now.

I continually get the following error:

Standard Mode: missing DMI

each time I try to install win 98. I have tried to clear the cmos, but still get the same error message.

Can someone help or explain please?
Thanks
