strange df output?

Here's the output I get from a df command on our pentium 100 with an
NCR53C8xx card and a 4GB Seagate Hawk.

Filesystem 1024-blocks Used Available Capacity Mounted on
/dev/sda1 997580 942748 3297 100% /
/dev/sda2 993614 205329 736954 22% /var
/dev/sda3 1982113 994793 884864 53% /home

Do I simply need to upgrade a package that I forgot about? This also
happens with my EIDE drive. Thanks much
