I have a gateway essential 433mz PROCESSOR 191 mb RAM 10 gig hard drive running windows 98 and I would like to put in a secondary hard drive and more memory, problem is I dont know how big a secondary hard drive or how much more memory I can install with out problems. Any advise and help appriciated. ThanksWhy do you want add memory? You have PLENTY for Win 98. Are you planning to install Win XP? Anyway, to see how much memory you could add, I suggest you visit www.crucial.com and use their memory advisor.You will need to at least know the Gateway model number to do that. It should be on the case.

You can add another hard drive if there is ROOM for it inside the case, that is a bracket for it to go into. If not, then the existing drive could be replaced. Does the machine run fine? I agree that your RAM is more than sufficient for Windows 98.Without knowing any details about your computer's BIOS, I think I'd not get a drive larger than 80GB.Thank you, the old gateway runs great! in fact better sometimes than this DELL I am on now. If the ram is fine then I would just like to replace or add another hard drive. Thanks again.
