Key Features
Ultra ATA
The Ultra ATA interface enables the Ultra DMA/33 protocol to increase the
burst data transfer rate to 33 megabytes per second. Additionally, Ultra ATA
provides new data verification checks to ensure the integrity of transferred
data. Ultra ATA maintains backward compatibility with the existing ATA
standard for IDE devices. This means devices which transfer data at differ-
ent speeds may be connected to the same Ultra ATA data cable; the system
will detect and use the correct speed for each device. Note that Ultra ATA
drives and IDE devices can be connected to either the Primary IDE connec-
tor or to the Secondary IDE connector. However, use of a non-Ultra ATA IDE
cable on either connector is not supported for Ultra ATA drives (the perfor-
mance of an Ultra ATA drive with a non-Ultra ATA cable could be unpredict-
able and lead to data loss).
Multi Boot
With the Multi Boot feature, the order in which your PC will boot from a
device is no longer determined by the physical connection of the device. The
user can connect IDE devices to the Ultra ATA cable in any order and then
select the boot order for all bootable drives (including floppy drive, CD-ROM
drive, and SCSI drives) with the HP Setup program.
Intel 440LX AGPset
Features
This Intel chipset is optimized for Pentium II processor-based systems. It
provides support for ACPI to permit increased manageability across the cor-
porate network. It is AGP-enabled for enhanced graphics performance. The
chipset also provides support for Ultra DMA/33.
Advanced Configuration
and Power Interface
ACPI is an open standard for enabling the operating system to control power
management in a PC. It enables a PC to switch on instantly when the user
needs it and remain available for remote management when switched off.
Accelerated Graphics
Port and RAMBUS
AGP technology accelerates the flow of data between the Pentium II proces-
sor, the video graphics controller, and system memory. It also allows the
transfer of graphics tasks off the PCI bus, freeing PCI bandwidth for other I/
O-intensive applications. The integrated Cirrus Logic Laguna3D graphics
accelerator supports AGP and also uses the RAMBUS memory architecture
which supports data transfers at up to 540 MHz between the graphics accel-
erator and the RAMBUS memory.
