Introduction
1 Introduction
This document is intended for Original Equipment Manufacturers and BIOS vendors
creating Intel^® I/O Controller Hub 7 (ICH7) Family based products. This document is
the datasheet for the following:
• Intel^® 82801GB ICH7 (ICH7)
• Intel^® 82801GR ICH7 RAID (ICH7R)
• Intel^® 82801GDH ICH7 Digital Home (ICH7DH)
• Intel^® 82801GBM ICH7 Mobile (ICH7-M)
• Intel^® 82801GHM ICH7 Mobile Digital Home (ICH7-M DH)
• Intel^® 82801GU ICH7-U Ultra Mobile (ICH7-U)
Section 1.2 provides high-level feature differences for the ICH7 Family components.
Note:
Throughout this datasheet, ICH7 is used as a general ICH7 term and refers to the
82801GB ICH7, 82801GR ICH7R, 82801GDH ICH7DH, 82801GBM ICH7-M, 82801GHM
ICH7-M DH, and 82801GU ICH7-U components, unless specifically noted otherwise.
Note:
Throughout this datasheet, the term “Desktop” refers to any implementation, be it in a
desktop, server, workstation, etc., unless specifically noted otherwise.
Note:
Throughout this datasheet, the terms “Desktop”, “Digital Home” “Mobile”, and “Ultra
Mobile” refer to the following components, unless specifically noted otherwise:
• Desktop refers to the 82801GB ICH7, 82801GR ICH7R, and 82801GDH ICH7DH.
• Digital Home refers to the 82801GDH ICH7DH and 82801GHM ICH7-M DH.
• Mobile refers to the 82801GBM ICH7-M, and 82801GHM ICH7-M DH.
• Ultra Mobile refers to the 82801GU ICH7-U.
Note:
“Desktop and Mobile Only” refers to all components in this document except the
82801GU ICH7-U Ultra Mobile component.
This datasheet assumes a working knowledge of the vocabulary and principles of PCI
Express*, USB, IDE, AHCI, SATA, Intel^® High Definition Audio (Intel^® HD Audio),
AC ’97, SMBus, PCI, ACPI and LPC. Although some details of these features are
described within this manual, refer to the individual industry specifications listed in
Table 1-1 for the complete details.
