No problem! I spend enough time seeing 98 restored and reinstalled on several systems in those days!
First knowing the actual size of the hard drive 98 will go on does help if you are planning only one single primary partition. The basic FDisk utility first seen on the 98 startup floppy that came along with the retail version of 98 was a far cry from seeing any worth on the drives that suddenly saw a sudden increase in capacity in just a short time.
Originally that less then 20gb while in theory 98 supported upto 2tb on a single partition. The updated version of FDisk later released by Microsoft then supported upto 64gb while drive manufacturers were then seeing utilities like WD's DrFat32 where you could then create and format a 250gb ide drive as well as a 2.5gb model.
How's that so far?
