Recommendations for Configuring an ATAPI Device

Normal, no ATAPI
Disk and CD-ROM for enhanced IDE systems
Legacy IDE System with only one cable
Enhanced IDE with CD-ROM and a tape or two CD-ROMs

3.1.5 ISA Plug and Play

If you select in Setup to boot with a Plug and Play OS (see Section 3.2.4.1), the BIOS auto-
configures only ISA Plug and Play cards that are required for booting (IPL devices). If you select
to not boot with a Plug and Play OS, the BIOS auto-configures all Plug and Play ISA cards.

3.1.6 ISA Legacy Devices

Since ISA legacy devices are not auto-configurable, the resources for them must be reserved. You
can reserve resources in the Setup program or with an ISA configuration utility (see Section 5.2 for
a Web site address).
The computer's configuration information is stored in ESCD format. You can clear the ESCD data
by moving the CMOS Clear jumper (see Section 1.13.3).

3.1.7 Desktop Management Interface

Desktop Management Interface (DMI) is a method of managing computers in an enterprise. The
main component of DMI is the Management Information Format (MIF) database, which contains
information about the computer and its components. Using DMI, a system administrator can
obtain the system types, capabilities, operational status, installation date and other information
about the computer's components. The DMI specification requires that certain information about
the computer's motherboard be made available to an applications program. This information is
located in a series of data structures which are accessed in various ways by the DMI service layer.
Component instrumentation allows the service layer to gain access to information stored in the
general-purpose area of non-volatile RAM. The MIF database defines the data and provides the
method for accessing the information.
The BIOS support for DMI enables the maximum benefit from applications such as LANDesk
Client Manager from Intel. The BIOS stores and can report on the following types of DMI
information:
BIOS data, such as the BIOS revision level
Fixed information, such as data about the motherboard, peripherals, serial numbers and asset
tags, etc.
Information discovered during bootup, such as memory size, cache size, processor speed, etc.
Dynamic information, such as event detection
