it needs at least 256MB, better with 512MB. Any less and it wont be worth your trouble. In addition, make sure your hard drive is at least 8GB (some may feel comfortable with less). Didn't answer your question, but thought I would save you aggravation if your machine isn't up to snuff
i have windows 98SE currently installed into my computer and i just got XP home edition. it wasnt the upgrade, however, so i have im left with the choice of either reformatting my harddrive and installing XP, or creat a dual-booting system and make one harddrive for 98se and on for XP. i was told that XP cannot run some older programs (being a gamer, thats gonna be annoying.) which is the best decision...what are the pros and cons?
