Table 49 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 49. Normal 1-2 3 BIOS Setup Configuration Jumper Settings Jumper Setting 1 Function/Mode Configuration The BIOS uses current configuration information and passwords for booting.

Figure 17 illustrates the mechanical form factor for the D845HV board. The outer dimensions are 9. 60 inches by 9. 60 inches [243. 84 millimeters by 243. 84 millimeters]. Location of the I/O connectors and mounting holes are in compliance with the ATX specification (see Section 1. 4). NOTE When installing the board in a microATX chassis, make sure that peripheral devices are installed at least 1. 5 inches above the main power connector, the diskette drive connector, and the IDE connector, and the DIMM sockets. 6. 50[165. 10] 6. 10[154. 94] 5. 20[132. 08] 0. 00 2. 85[72. 39] 3. 10[78. 74] 9. 05[229. 87] 0. 55[13. 97] 0. 00 0. 80 [20. 32] 2. 60 [66. 04] 8. 80 [223. 52] OM11436 Figure 17.

D845WN Board Dimensions 75 Intel Desktop Board D845HV/D845WN Technical Product Specification 2. 10. 3 I/O Shield The back panel I/O shield for D845HV and D845WN boards must meet specific dimension and material requirements. Systems based on this board need the back panel I/O shield to pass certification testing. Figure 19 shows the critical dimensions of the chassis-dependent I/O shield for boards with the onboard LAN subsystem. Figure 20 shows the critical dimensions of the I/O for 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. 4 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. 01 is available from Intel. 6. 390 Ref [162. 300] 0. 063±0. 005 [1. 600±0. 120] 0. 787±0. 010 TYP [20±0. 254] 0. 039 Dia.
