Add-In Board Slots; Video; Scsi Controller; Ich4 Ide Controller - Intel SR870BN4 - Server Platform - 0 MB RAM Product Manual

Add-In Board Slots

The I/O board has three 64-bit/133 MHz hot-plug PCI-X and five 64-bit/100 MHz PCI-X
expansion slots contained in the following three PCI segments:
P64H2,0 provides for PCI-X slots 1 through 3 (all 100 MHz) and the dual channel LVDS
controller
P64H2,1 provides for PCI-X slots 4 through 6 (two 100 MHz and one 133 MHz)
P64H2,2 provides for PCI-X slots 7 and 8 (both 133 MHz)

Video

The onboard, integrated ATI RAGE XL 64-bit SVGA chip contains an SVGA controller that is
fully compatible with industry video standards. The system comes with 8 MB of 10-nanosecond
onboard video memory.
The video controller supports pixel resolutions of up to 1600 x 1200 and up to 16.7 million colors.
The controller also provides hardware accelerated bit block transfers of data.
The SVGA controller supports analog VGA monitors (single and multiple frequency, interlaced
and noninterlaced) with a maximum vertical retrace noninterlaced frequency of 100 Hz.
The video connector is located on the I/O riser. See Figure 8 on page 27 for the location of this
connector.

SCSI Controller

A LSI 53C1030 Ultra3 SCSI chip is a highly integrated bus master, dual-channel SCSI I/O
processor for SCSI initiator and target applications. The chip supports dual channel, Ultra3
(Fast-80) SCSI functionality. This device interfaces the PCI bus to two Ultra3 SCSI buses. The
53C1030 is a fully autonomous device, capable of managing multiple I/O operations and associated
data transfers from start to finish without host intervention. The 53C1030 provides power
management feature support in accordance with the PCI Bus Power Management Interface
Specification.

ICH4 IDE Controller

The ICH4 IDE controller is a multifunction device on the I/O Board that acts as a PCI-based Fast
IDE controller. The device controls the following:
PIO and IDE DMA/bus master operations
Mode 4 timing
Transfer rates up to 22 MB/sec (33 MB/sec using ultra DMA transfers)
Buffering for PCI/IDE burst transfers
Master/slave IDE mode
