1.6.2.1 IDE Interfaces
The ICH2’s IDE controller has two independent bus-mastering IDE interfaces that can be
independently enabled. The IDE interfaces support the following modes:
• Programmed I/O (PIO): CPU controls data transfer
• 8237-style DMA: DMA offloads the CPU, supporting transfer rates of up to 16 MB/sec
• Ultra DMA: DMA protocol on IDE bus supporting host and target throttling and transfer rates
of up to 33 MB/sec.
• Ultra ATA-66: DMA protocol on IDE bus supporting host and target throttling and transfer
rates of up to 66 MB/sec. ATA-66 protocol is similar to ATA-33 and is device driver
compatible. ATA-66 uses faster timings and requires a specialized cable to reduce reflections,
noise, and inductive coupling.
• Ultra ATA-100: DMA protocol on IDE bus allows host and target throttling. The ICH2 Ultra
ATA-100 logic can achieve read transfer rates up to 100 MB/sec and write transfer rates up to
88 MB/sec. The higher quality cable used for ATA-66 DMA support is adequate to reduce
reflections, noise, and inductive coupling for ATA-100 operation.
23
Intel® Desktop Board D815EEA Technical Product Specification
The IDE interfaces also support ATAPI devices (such as CD-ROM drives) and ATA devices using
the transfer modes listed in Table 70 on page 107.
The BIOS supports logical block addressing (LBA) and extended cylinder head sector (ECHS)
translation modes. The drive reports the transfer rate and translation mode to the BIOS.
The D815EEA board supports laser servo (LS-120) diskette technology through its IDE interfaces.
The LS-120 drive can be configured as a boot device by setting the BIOS Setup program’s Boot
menu to one of the following:
• ARMD-FDD (ATAPI removable media device – floppy disk drive)
• ARMD-HDD (ATAPI removable media device – hard disk drive)
For information about Refer to
The location of the IDE connectors Figure 11, page 63
The signal names of the IDE connectors Table 43, page 68
BIOS Setup program’s Boot menu Table 76, page 114

Product Description
1.6.2.3 Real-Time Clock, CMOS SRAM, and Battery
The real-time clock provides a time-of-day clock and a multicentury calendar with alarm features.
The real-time clock supports 256 bytes of battery-backed CMOS SRAM in two banks that are
reserved for BIOS use.
A coin-cell battery (CR2032) powers the real-time clock and CMOS memory. When the computer
is not plugged into a wall socket, the battery has an estimated life of three years. When the
computer is plugged in, the standby current from the power supply extends the life of the battery.
The clock is accurate to ± 13 minutes/year at 25 ºC with 3.3 VSB applied.
The time, date, and CMOS values can be specified in the BIOS Setup program. The CMOS values
can be returned to their defaults by using the BIOS Setup program.
✏ NOTE
If the battery and AC power fail, standard defaults, not custom defaults, will be loaded into CMOS
RAM at power-on.
✏ NOTE
The recommended method of accessing the date in systems with D815EEA boards is indirectly
from the Real-Time Clock (RTC) via the BIOS. The BIOS on D815EEA boards contains a century
checking and maintenance feature. This feature checks the two least significant digits of the year
stored in the RTC during each BIOS request (INT 1Ah) to read the date and, if less than 80 (i.e.,
1980 is the first year supported by the PC), updates the century byte to 20. This feature enables
operating systems and applications using the BIOS date/time services to reliably manipulate the
year as a four-digit value.
For information about Refer to
Proper date access in systems with D815EEA boards Section 1.2, page 16

1.8.2 Digital Video Output (DVO) Connector
The board routes the Intel 82815E GMCH DVO port to an onboard 40-pin DVO connector. The
DVO connector can be cabled to a DVI or TV out card to enable digital displays or TV out
functionality. The Digital Visual Interface (DVI) specification provides a high-speed digital
connection for visual data types when using the integrated graphics controller. This interface is
active only when the integrated graphics controller is enabled.
The DVI interface allows interfacing with a discrete Transmission Minimized Differential
Signaling (TMDS) transmitter to enable platform support for DVI compliant digital displays or
with a discrete TV encoder for TV Out functionality.
