intel ? desktop board d845ept2 specification update v i preface this document is an update to the specifications contained in the intel ? desktop board d845ept2 technical product specification (order number a84913). it is intended for hardware system m anufacturers and software developers of applications, operating systems, or tools. it will contain specification c hanges, errata, specification clarifications, and documentation changes. refer to the intel ? pentium ? 4 processor specification update (order number 249199) for specification updates concerning the intel pentium 4 processor and that may apply to the desktop board d845ept2. unless otherwise noted in this document, it should be assumed that any processor errata for a given stepping are applicable to the altered assembly (aa) revision(s) associated with that stepping. refer to the intel ? 845 chipset: 82845 memory controller hub e (mch) for ddr specification update (order number 298603) for specification updates concerning the 82845e mch controller and that may apply to the desktop board d845ept2. unless otherwise noted in this document, it should be assumed that any mch errata for a given stepping are applicable to the altered assembly (aa) revision(s) associated with that stepping. refer to the intel ? 82801db i/o controller hub 4 (ich4) specification update (order number 290745) for specification updates concerning the 82801db i/o controller hub and that may apply to the desktop board d845ept2. unless otherwise noted in this document, it should be assumed that any ich 4 errata for a given stepping are applicable to the altered assembly (aa) revision(s) associated with that stepping. nomenclature specification changes are modifications to the current published specifications. these changes will be incorporated in the next release of the specifications. errata are design defects or errors. characterized errata may cause the desktop board d845ept2 ? s behavior to deviate from published specifications. hardware and software designed to be used with any given altered assembly (aa) and bios revision level must assume that all errata documented for that aa and bios revision level are present on all desktop boards. specification clarifications describe a specification in greater detail or further highlight a specification ? s impact to a complex design situation. these clarifications will be incorporated in the next release of the specifications. documentation changes include typos, errors, or omissions from the current published specifications. these changes will be incorporated in the next release of the specifications.

intel ? desktop board d845ept2 specification update 4 summary table of changes the following table indicates the specification changes, errata, specification clarifications, or documentation changes that apply to the desktop board d845ept2. intel intends to fix some of the errata in a future revision of the desktop board, and to account for the other outstanding issues through documentation or specification changes as noted. this table uses the following notations: codes used in summary table doc: document change or update that will be implemented. planfix: this erratum is intended to be fixed in a future revision of the desktop board, driver, or bios. fixed: this erratum has been previously fixed. nofix: there are no plans to fix this erratum. shaded: this erratum is either new or modified from the previous version of the document. no. plans errata 1 fixed intel ? 82801db i/o controller hub 4 (ich 4) erratum 7 2 planfix wake from an acpi sleep state using wake methodologies may fail 3 planfix intel 82801db i/o controller hub 4 (ich 4) erratum 8 no. plans documentation changes 1 doc change to description of table 40, section 2.8.3, external i/o connectors
intel ? desktop board d845ept2 specification update 5 errata 1. intel ? 82801db i/o controller hub 4 (ich 4) erratum 7 p roblem : for a complete description of the ich 4 erratum 7, see the intel ? 82801db i/o controller hub 4 (ich 4) specification update, order number 290745 found at http://developer.intel.com/design/chipsets/specupdt . i mplication : for a complete description of the ich 4 erratum 7, see the intel 82801db i/o controller hub 4 (ich 4) specification update, order number 290745 found at http://developer.intel.com/design/chipsets/specupdt . w orkaround : none. s tatus : this erratum was fixed in the b0 chipset stepping. 2. wake from an acpi sleep state using wake methodologies may fail p roblem : the desktop board hardware leaves the lan reset (lan_rst#) signal unasserted before and after the resume well power (vccsus3_3 and vccsus1_5) is valid, instead of asserting it for 10 ms after valid power, which is required by the intel 82801db i/o controller hub 4 (ich4) datasheet (order number 290744). the result is that lan wake attempts may fail. note: wake from lan* using the magicpacket* utility will not be affected by this errata. i mplication : users that take advantage of lan wake methods to wake systems from an acpi sl eep state may experience some wake failures. w orkaround : none. s tatus : this erratum may be fixed in a future bios revision. 3. intel 82801db i/o controller hub 4 (ich 4) erratum 8 p roblem : for a complete description of the ich 4 erratum 8, see the intel 82801db i/o controller hub 4 (ich 4) specification update, order number 290745 found at http://developer.intel.com/design/chipsets/specupdt . i mplication : for a complete description of the ich 4 erratum 8, see the intel 82801db i/o controller hub 4 (ich 4) specification update, order number 290745 found at http://developer.intel.com/design/chipsets/specupdt . w orkaround : none. s tatus : this erratum may be fixed in a future chipset stepping
