Page 47: Ultra Ata Drive Guidelines And Features
Ultra ATA Drive Guidelines and Features Ultra ATA Jumpers Ultra ATA drives are configured by means of jumper settings. Factory-installed drives ship with the jumpers preset to the cable-select mode; therefore, no jumper setting changes are required on factory pre installed, replacement, or option drives. With cable-select, the drive is configured as either Master (Drive/Device 0) or Slave (Drive/Device 1) by its physical attachment to the cable.

Ultra ATA Drive Guidelines and Features Single-Drive Cable System Board Blue Face Two-Drive Cable System Board Blue Face On a two-drive cable, the Drive/Device 0 connector is always the farthest one from the system board connector and the Drive/Device 1 connector is always the closest to the system board connector.
Page 49: Device Classes
4.3.1 Device Classes In order to determine the best drive attach sequence, ATA/ATAPI drives are segregated into four different classes based upon the bandwidth demands they place on an ATA controller.

4.5 Drive Capacities The combination of the file system and the operating system used in the computer determines the maximum usable size of a drive partition. A drive partition is the largest segment of a drive that may be properly accessed by the operating system. A single hard drive may therefore be subdivided into a number of unique drive partitions in order to make use of all of its space.

If an incorrect screw is used during the reassembly process, it can damage the unit. HP strongly recommends that all screws removed during disassembly be kept with the part that was removed, then returned to their proper locations.
Page 61: Cables And Connectors
5.4.4 Cables and Connectors Most cables used throughout the unit are flat, flexible cables. These cables must be handled with care to avoid damage. Apply only the tension required to seat or unseat the cables during insertion or removal from the connector. Handle cables by the connector whenever possible. In all cases, avoid bending or twisting the cables, and ensure that the cables are routed in such a way that they cannot be caught or snagged by parts being removed or replaced.

Page 141 AMD-Based Systems Computers equipped with AMD-based processors come with Double Data Rate-Synchronous Dynamic Random Access Memory (DDR-SDRAM) Dual Inline Memory Modules (DIMMs). The memory sockets on the system board can be populated with industry-standard DIMMs. These memory module slots are populated with at least one pre installed memory module. To achieve the maximum memory support, you may be required to replace the pre installed DIMM with a higher capacity DIMM.
Page 142: Dimm Sockets
Memory The following processor bus frequencies are required for the system to run at the supported memory frequencies. Memory Frequency 266 MHz 333 MHz 400 MHz If a memory frequency is paired with an unsupported processor bus frequency, the system will run at the highest supported memory speed.
Page 143 The system will automatically operate in single channel mode or a higher-performing dual channel mode, depending on how the DIMMs are installed. In single channel mode, the maximum operational speed is determined by the slowest DIMM in the system. For example, if the system is populated with a DIMM that is 266 MHz and a second DIMM that is 333 MHz, the system will run at the slower of the two speeds.
