Dell uses motherboards and BIOSs from several manufacturers, their computers use a variety of power on self test (POST) error messages. Instead of listing each model's error messages, this list provides links to the support pages of popular Dell workstations and servers. If you don't see a particular Dell machine listed here, check Dell's support Web site http://support.dell.com/ . Send us a link to the machine’s POST codes via the mail-to link on the last page of this document.
