DC power supply from +1.10V to +1.85V. System Memory The 845E-ANT mainboard uses Double Data Rate Dual Inline Memory Modules (DDR DIMM). Each mainboard has two 184-pin DIMM sockets. These sockets support 2.5V (power level) single-sided or double-sided PC1600 (DDR200) or PC2100 (DDR266) DDR DIMM modules.

USB Ports USB allows data exchange between your computer and a wide range of simultaneously accessible external Plug and Play peripherals. The 845E-ANT mainboard is equipped with six USB2.0 connectors. USB 1 and USB 2 are external connectors. They can be found on the PC 99 ATX connector. The other USB connectors are internal connectors and can be used to connect other USB devices.

Read back capability that displays temperature, voltage and fan speed. 1.4.1. Hardware Monitoring System Utility The 845E-ANT mainboard comes with the Hardware Monitoring System utility contained on the CD. It is capable of monitoring the systems hardware conditions such as the temperature of the processor, voltage, and the speed of both the CPU and chassis fans.

CPU. 2.3.2. Memory Modules The 845E-ANT mainboard has two 184-pin DDR DIMM slots and is able to support a maximum memory of 2 GB. The DDR DIMM slots are located on the right hand side of the board. To install the DIMMs into these slots, make sure the white lever at each side of the slot has been pulled down to an angle of approximately 45.

This mainboard complies with Plug and Play (PnP) specifications. When- ever a PnP compliant card is added the system will automatically be configured and the IRQ’s will be assigned automatically.

Type: 40 pin blocks The 845E-ANT mainboard has two IDE connectors: a primary and secondary. Each IDE connector can support two IDE drives. This mainboard can therefore support up to four IDE devices. If you install two hard drives, you need to con- figure the second drive to slave mode in the BIOS setup.

Type: 4 pin un-housed This 845E-ANT mainboard has one CD-IN connector and one AUX-IN connec- tor. The CD-IN connector is used to connect the CD ROM audio out and allows the system to receive audio input from the CD ROM. The AUX-IN connector allows the system to receive signals from other audio devices like a radio or tape.

Insert the jumper cap on Pin 2 and Pin 3 for 3 ~ 5 seconds. Pull out the jumper cap and replace it on Pin 1 and Pin 2. Turn your PC on and run the BIOS setup program. The 845E-ANT MAINBOARD Page 23...
This mainboard supports four IDE Hard Drives. These fields allow you to set your Hard Drive parameters. Move the selection bar to the IDE Hard Drive you want to configure. Press the "ENTER" key. If you select “AUTO” the system BIOS will detect the HDD type automatically. The 845E-ANT MAINBOARD Page 25...

$> Drive A /B The 845E-ANT mainboard can support up to two floppy disk drives. These two selection fields allow you to select the floppy drives that are installed on your computer. Select the correct specifications for the diskette drive(s) installed on your computer.
If enabled the amount of time required to run the power-on self-test (POST) will decrease. A quick POST skips certain steps. We recommend that you dis- able quick POST. It is better to find a problem during POST than to lose data during your work. The 845E-ANT MAINBOARD Page 27...

40 or 80 tracks. Only 360-KB floppy drives have 40 tracks; drives with 720 KB, 1.2 MB, and 1.44 MB capacity all have 80 tracks. Very few modern PCs have 40-track floppy drives so we therefore recommend that you set this field to Disabled to save time. Page 28 The 845E-ANT MAINBOARD...

OS Select For DRAM > 64MB Only select OS2 if you are running an OS/2 operating system with a RAM greater than 64 Mb. Otherwise, for all other operating systems, use the default setting “Non-OS2”. The 845E-ANT MAINBOARD Page 29...

If you look at the top of Pin 2 in Pic 2b you will see that there is no connec- tion to the AGP card. This means that this is a 3.3 volt AGP card and can ® therefore not be used on an Intel 845 mainboard. The 845E-ANT MAINBOARD Page 45...

The first method is a physical check and the sec- ond method is a simple measurement between Pin 2 (on Side A) and any ground point on the card. The second method is the recommended method but both methods SHOULD suffice. Page 46 The 845E-ANT MAINBOARD...
