Gateway MFATXSTLKTH 300SE WITH XP Home

Sorry, Gateway's site requires serial number input to determine the original factory configuration.
You can access their records here;
and see a review of the 300SE from back in the day here
I would have thought XP was installed NTFS, but without the serial number I couldn't check very easily.
Please also see FAT & NTFS and FAT vs NTFS for a primer on the two file system that may help you decide which to choose if you are reinstalling XP on your system.

If you need further assistance please post back with a comment to this thread. If I've managed to answer your question or solve a problem, please take a moment to kindly rate this post....thanks!
