Revision History Revision -001 Revision History First release of the Desktop Board D845GEBV2/D845GERG2 Technical Product Specification. Intel® Date October 2002 This product specification applies to only standard Intel® Desktop Boards D845GEBV2 and D845GERG2 with BIOS identifier RG84510A. 86A. Changes to this specification will be published in the Intel Desktop Board D845GEBV2/D845GERG2 Specification Update before being incorporated into a revision of this document. INFORMATION IN THIS DOCUMENT IS PROVIDED IN CONNECTION WITH INTEL PRODUCTS. [. . . ] Configuration Audio line out signals are routed to the back panel audio line out connector. The back panel audio line out connector is shown in Figure 12 on page 60. Jumper Setting 1 3 5 7 9 10 2 4 6 1 3 5 7 9 2 4 6 No jumpers installed 10 # INTEGRATOR'S NOTE When the jumpers are removed and this connector is used for front panel audio, the back panel audio line out and mic in connectors are disabled. 2. 9. 2 BIOS Setup Configuration Jumper Block The 3-pin jumper block determines the BIOS Setup program's mode. Table 41 describes the jumper settings for the three modes: normal, configure, and recovery. When the jumper is set to configuration mode and the computer is powered-up, the BIOS compares the processor version and the microcode version in the BIOS and reports if the two match. Table 41. Normal 1-2 Configure 2-3 Recovery None 3 1 BIOS Setup Configuration Jumper Settings Jumper Setting 3 1 Function/Mode Configuration The BIOS uses current configuration information and passwords for booting. A recovery diskette is required. 3 1 73 Intel Desktop Board D845GEBV2/D845GERG2 Technical Product Specification 2. 10 Mechanical Considerations 2. 10. 1 D845GEBV2 Form Factor The Desktop Board D845GEBV2 is designed to fit into an ATX-form-factor chassis. Figure 19 illustrates the mechanical form factor for the Desktop Board D845GEBV2. The outer dimensions are 12. 00 inches by 8. 20 inches [304. 80 millimeters by 208. 28 millimeters]. Location of the I/O connectors and mounting holes are in compliance with the ATX specification (see Section 1. 5). . 800 [20. 32] 6. 50 [165. 10] 6. 10 [154. 94] 5. 20 [132. 08] 0. 00 1. 700 [42. 5] 2. 95 [74. 93] 2. 300 [58. 42] 0. 00 2. 600 [66. 04] 9. 050 [229. 87] 8. 800 [223. 52] OM13583 Figure 19.

Systems based on these Desktop Boards need the back panel I/O shield to pass certification testing. Figure 21 shows the I/O shield for Desktop Boards with the onboard LAN subsystem. Figure 22 shows the I/O shield for Desktop Boards without the onboard LAN subsystem. Additional design considerations for I/O shields relative to chassis requirements are described in the ATX specification. See Section 1. 5 for information about the ATX specification. NOTE The I/O shield drawings in this document are for reference only. An I/O shield compliant with the ATX chassis specification 2. 03 is available from Intel. 6. 390 REF [162. 300] 0. 063 0. 005 [1. 600 0. 120] 0. 787 3x Dia 0. 039 [1. 000] 0. 884 [22. 450] 0. 276 [7. 012] 0. 000 [0. 000] 0. 465 [11. 811] 0. 567 [14. 400] 0. 010 TYP [20 0. 254] 3x Dia 0. 330 [8. 380] 8X R0. 5 MIN A 0. 519 [13. 190] 0. 027 [0. 690] 0. 465 [11. 810] 0. 472 [12. 000] 2. 081 [52. 854] 3. 219 [81. 768] 4. 840 [122. 950] 5. 771 [146. 577] Pictorial View 1. 195 [30. 360] 0. 447 [11. 345] 1. 807 [45. 892] 0. 000 [0. 000] OM11487 Figure 21.
