But in your case, even you use the win98 CD it still wont take efettive, couse your HDD may be formated by NTFS format,and Win98 only support Fat16/32 HDD format,
as a advise, repatition your HDD and format it with fat32,but if your HDD is over 120GB, and you are a CAINIAO, better call a technician to do it!!
