IBM Deskstar 25GP Installation And Reference Manual page 19

Note: If your drive is already formatted, a Welcome screen is displayed with three options; guided
install, partition and format, and advanced options.
• The message "Insert a DOS system disk or a Windows 9x startup disk into the floppy
drive A:" is displayed. Insert the startup disk you will be using to install the operating
system.
• Choose the type of File Allocation Table (FAT) to be used in your drive partitions.
Note: Select FAT32 or FAT16 if you are using Windows 95 SR2 or Windows 98. FAT 32 partitions
utilize disk space more efficiently and may be greater than 2GB in size. If you are using DOS,
Windows 3.1x, or an earlier version of Windows 95, select FAT16.
