Specification Update AMD GeodeTM NX DB1500 Development Board Document Revision History Date Revision Changes September 2004 A Initial version January 2005 B Added Errata item #4 The AMD GeodeTM NX DB1500 Development Board may contain design defects or errors known as errata that cause its behavior to differ from the published specification. Characterized Board Errata are documented in this Specification Update. As needed, this Specification Update provides a summary table and more detailed descriptions of permanent Specification Changes made to the published product documentation. This Specification Update also provides a summary table and more detailed descriptions of known Documentation Errata. To establish Specification Update information, AMD tests to errata, specification changes, and current documentation. Specification Update information supersedes current published documentation. NOTE: BIOS errata is outlined in the release notes of each code release. Please see the specific code release for your BIOS version for more information. Board Errata Summary Table The following table lists the status of all characterized board errata. A blank field under a particular Revision implies that the listed erratum does not apply to that version of the development board. Errata No. Revision Errata 1.1 1.2 1 X Start-up failure at power-up. 2 X Start-up failure of the on-board 2.5V regulator. 3 X Failure to resume from S3 (Suspend to RAM). 4 X X Over-voltage condition on processor SOFTVID output pins. Board Errata 1. Start-up failure at power-up. Description The problem surfaces as a failure of the system to start up at power-on. No video is present. A system reset typically clears the error. 32328B Publication# 32328BRev: B Amendment/0 January 2005 January 2005 Issue Date: S P E C I F I C A T I O N U P D A T E The VIA KM400A S2K compensation resistor (R348) on the board was originally set at 60.2 ohms, 1% tolerance. In response to an errata released from VIA Technologies on the KM400A, the value has been changed to 49.9 ohms, 1% tolerance. Affected Revisions 1.1 Workaround Shipped boards should already have this rework implemented. Design revision 1.2 reflects this change. Status Fixe
