The BIOS version offered there is A05 (http://www.dell.com/support/drivers/us/en/19/DriverDetails/Product/dimension-2400?driverId=R70278&osCode=WW1&fileId=2731128804&languageCode=en&categoryId=BI).
But this machine is already running A05 (noted above -- dmi.bios.version: A05).
(I imagine you were glancing at dmi.board.version: A01 just a couple lines below that.)
