When using system frequency processor, DDR333 memory clocked MHz. This minimizes system latencies optimize system throughput.
NOTES
When DIMMs used, Power-On Self Test (POST) will take longer complete. Remove video card before installing upgrading memory avoid interference with memory retention mechanism. fully compliant with applicable SDRAM memory specifications, board should populated with DIMMs that support Serial Presence Detect (SPD) data structure. This allows BIOS read data program chipset accurately configure memory settings optimum performance. non-SPD memory installed, BIOS will attempt correctly configure memory settings, performance reliability impacted DIMMs function under determined frequency.

Parallel Interfaces
ICH5-R's Parallel controller independent bus-mastering Parallel interfaces that independently enabled. Parallel interfaces support following modes: Programmed (PIO): processor controls data transfer. 8237-style DMA: offloads processor, supporting transfer rates MB/sec. Ultra DMA: protocol supporting host target throttling transfer rates MB/sec. ATA-66: protocol supporting host target throttling transfer rates MB/sec. ATA-66 protocol similar Ultra device driver compatible. ATA-100: protocol allows host target throttling. ICH5-R's ATA100 logic achieve read transfer rates MB/sec write transfer rates MB/sec.
NOTE
ATA-66 ATA-100 faster timings require specialized cable reduce reflections, noise, inductive coupling. Parallel interfaces also support ATAPI devices (such CD-ROM drives) devices using transfer modes listed Section 4.4.4.1 page 105. BIOS supports Logical Block Addressing (LBA) Extended Cylinder Head Sector (ECHS) translation modes. drive reports transfer rate translation mode BIOS. Desktop Board D875PBZ supports Laser Servo (LS-120) diskette technology through Parallel interfaces. BIOS supports booting from LS-120 drive.

Interrupt Routing
This section describes interrupt sharing interrupt signals connected between connectors onboard devices. specification specifies interrupts shared between devices attached bus. most cases, small amount latency added interrupt sharing does affect operation throughput devices. some special cases where maximum performance needed from device, device should share interrupt with other devices. following information avoid sharing interrupt with add-in card. devices categorized follows specify their interrupt grouping: INTA: default, add-in cards that require only interrupt this category. almost cards that require more than interrupt, first interrupt card also classified INTA. INTB: Generally, second interrupt add-in cards that require more interrupts classified INTB. (This absolute requirement.) INTC INTD: Generally, third interrupt add-in cards classified INTC fourth interrupt classified INTD.
ICH5-R eight programmable interrupt request (PIRQ) input signals. interrupt sources either onboard from add-in card connect these PIRQ signals. Some interrupt sources electrically tied together Desktop Board D875PBZ therefore share same interrupt. Table shows example PIRQ signals routed. example, using Table reference, assume add-in card using INTA plugged into connector connector INTA connected PIRQB, which already connected ICH5-R audio controller. add-in card connector shares interrupt with onboard interrupt source.

System Management BIOS (SMBIOS)
SMBIOS Desktop Management Interface (DMI) compliant method managing computers managed network. main component SMBIOS Management Information Format (MIF) database, which contains information about computing system components. Using SMBIOS, system administrator obtain system types, capabilities, operational status, installation dates system components. database defines data provides method accessing this information. BIOS enables applications such third-party management software SMBIOS. BIOS stores reports following SMBIOS information: BIOS data, such BIOS revision level Fixed-system data, such peripherals, serial numbers, asset tags Resource data, such memory size, cache size, processor speed Dynamic data, such event detection logging
Non-Plug Play operating systems, such Windows NT*, require additional interface obtaining SMBIOS information. BIOS supports SMBIOS table interface such operating systems. Using this support, SMBIOS service-level application running non-Plug Play operating system obtain SMBIOS information.
