Making a DOS-Bootable Diskette 13

Making a DOS-Bootable Diskette

For installation and conﬁguration procedures that require you to boot from DOS, you cannot successfully use the MS-DOS prompt from within Windows. Perform a “clean” boot from DOS or use a DOS boot disk.

NOTE: To use the CD-ROM drive on a PC or server in a DOS environment, the DOS drivers for the CD-ROM drive must be installed. Consult the documentation that accompanied your CD-ROM drive or your motherboard for information about how to install these drivers.

NOTE: If the PC or server is only running DOS and a CD-ROM drive is not installed, you must install the NIC software using installation diskettes. For more information about installation diskettes

Go to: Diskette Installation

To make a DOS-bootable diskette:

1 Insert a blank, formatted diskette in drive A. 2 At the DOS prompt, enter:

sys a:

System ﬁles are copied to the diskette.

3 Remove the diskette from drive A and attach a label for future reference.

Diskette Installation Installation diskettes are not included with this product. If you do not have

a CD-ROM drive installed in your PC, you need to locate a system with a CD-ROM drive and create installation diskettes from the EtherCD that accompanied this product.

3CR990 NICS

NIC Overview The 3CR990 network interface cards (NICs) repr esent a new generation of secure,

intelligent client NICs with an on-board RISC processor (3XP pr ocessor). The RISC processor is designed to optimize system and network performance. Optimization occurs by ofﬂoading key networking and security tasks even when running bandwidth-intensive applications such as voice, video, imaging, and Internet and intranet applications. These NICs connect your PCI-compliant PC to a 10 Mbps or 100 Mbps Ethernet network and provide advanced features for high performance and secure transactions.

The 3CR990 NICs provide up to 3DES (Data Encryption Standard 168-bit) encryption. Encryption processing is handled entirely by the RISC processor and the encryption chip that reside on the 3CR990 NICs.

The onboard encryption chip enables true end-to-end network security (IPSec) at the data capacity of the connected network cable (wire speed), without sacriﬁcing performance.

The following ﬁgure shows the 3CR990 NIC and the location of its major components.

Encryption chip

TX DATA

3XP processor

3CR990 NICs support up to 168-bit (3DES) encryption

NIC Features The 3CR990 NICs provide these features for supported IP and IPX environments:

■ Integrated Boot ROM

■ Remote Wake-Up

■ Desktop Management Interface (DMI)

■ DHCP server prevention

■ Broadcast storm limitation

■ Ofﬂine diagnostics

Integrated Boot ROM Managed PC Boot Agent (MBA) software provides the multiprotocol preboot

ﬁrmware and tools. MBA adds management capabilities to the NIC by enabling the PC to boot from a network server, rather than from its local drive. 3CR990 NICs have an integrated boot ROM already installed on the NIC.

For information on conﬁguring and using the MBA, see the Managed PC Boot Agent (MBA) User Guide located on the EtherCD. Navigate the following path: CD ROM drive letter \ Installs \ Mba \ Manual, and then double-click 3ComGuide.exe to unzip the compressed user guide ﬁle.

NIC Features 17

MBA preboot support allows you to use management applications to perform tasks such as:

■ Installing and conﬁguring a new PC that has never been connected to

the network.

■ Upgrading software.

■ Scanning for viruses.

■ Performing disaster recovery tasks.

In addition to ﬁrmware, MBA has a complete set of tools, utilities, and pre-OS software that enables network administrators to perform tasks such as:

■ Reconﬁguring multiple systems at once.

■ Backing up hard drives automatically.

For more information on the management features supported by 3C990 NICs, access the 3Com World Wide Web site

Go to: http://www

.3com.com/managedpc.

Remote Wake-Up Remote Wake-Up provides the ability to remotely power-up a network PC.

When the PC is in sleep mode and receives a wake-up packet (Magic Packet frame) through the LAN, the NIC turns on the power to the PC. To use the Remote Wake-Up feature, a desktop management application is also required that is able to generate a Magic Packet Remote Wake-Up signal.

NOTE: The 3CR990 NICs provide a network connection with or without the Remote Wake-Up cable installed.

Your PC or server must be either 2.1 or 2.2 PCI speciﬁcation-compliant to use Remote Wake-Up. A PC that meets the PCI 2.1 speciﬁcation uses the 3-pin Remote Wake-Up connector on the PC motherboard. A PC that meets the PCI 2.2 speciﬁcation uses the PCI bus on the motherboard to handle Remote Wake-Up. (A 3-pin connector is not provided on the motherboard.)

Additionally, to support Remote Wake-Up, a PC must have a:

■ BIOS that supports Remote Wake-Up (power management capability)

■ 5-volt standby power supply unit rated at a minimum of 375 mA

If you are unsure whether your PC meets the requirements listed above, refer to your PC documentation or contact your PC manufacturer. For more information on Remote Wake-Up, including a list of PCs that currently support this feature, access the 3Com World Wide Web site

Go to: http://www

.3com.com/partners/acpi.

18 CHAPTER 2: 3CR990 NICS

Desktop

Management Interface

Desktop Management Interface (DMI) is a network management standard that is widely accepted for managing Intel-based computers. The 3Com DMI Agent allows any DMI management application to access information such as the NIC driver location, version, and size; packets sent statistics; crc receive errors; and much more.

The 3Com DMI Agent consists of a DMI browser with the following components:

■ DMI service layer

■ DMI agent

■ GUI installer

■ NDIS drivers

DHCP Server Prevention

This feature prevents the PC from acting like a DHCP server. All receive packets are passed through a DHCP ﬁlter and are discarded if they are deemed to be destined for the DHCP process.

Broadcast Storm Limitation

Broadcast throttling is implemented on both the transmit and receive data streams. The user can specify a transmit broadcast threshold as a percentage of the transmit bandwidth. The adapter monitors each data stream and discards any broadcast or multicast packets that exceed this limit.

To install DMI, on the EtherCD Welcome screen, click NIC Software,

DynamicAccess Technology, and Install 3Com DMI Agent now.

Ofﬂine Diagnostics This product provides ofﬂine diagnostics programs for conﬁguring, testing,

and troubleshooting 3CR990 NICs. The conﬁguration program within the DOS diagnostics program is used for a PC running Windows 2000, Windows NT 3.51, or DOS. The 3Com NIC diagnostics program (3Com NIC Doctor) is a windows-based program used for a PC running Windows 98, Windows 95, or Windows NT 4.0.

Windows 2000 Ofﬂoad Features

Additionally, the 3CR990 NICs support windows 2000 ofﬂoad features in an IP environment. The 3CR990 NIC Windows 2000 ofﬂoad features are designed to enhance the Windows 2000 operating system capabilities by ofﬂoading key TCP/IP networking and security tasks from the Windows 2000 operating system:

■ IPSec Ofﬂoad—reduces CPU utilization by allowing the 3XP processor and

a crypto chip on the NIC to perform data encryption operations.

■ TCP Segmentation Ofﬂoad—reduces CPU utilization by allowing the

3XP processor on the NIC to perform segmentation of TCP packets

■ IP and TCP checksum Ofﬂoad—reduced CPU utilization by allowing the

3XP processor on the NIC to perform the checksum calculation of TCP/IP

and UDP/IP packets

■ 802.1P Packet Priority Ofﬂoad—reduces CPU utilization by allowing the

3XP processor on the NIC to perform the insertion of the 802.1Q tag

header into the packet

Windows 2000 Offload Features 19

Enabling Ofﬂoads Windows 2000 provides the capability to individually enable or disable each of the

four ofﬂoad features. (The default setting for these features is enabled.)

NOTE: For users running the Beta 3 version of Microsoft Windows 2000, the Ofﬂoad function must be globally enabled in Windows 2000 before individual ofﬂoad features can be enabled or disabled.

See the readme.txt ﬁle in the root of the EtherCD for the latest information about enabling and disabling ofﬂoad features in the Beta 3 version of Windows 2000.
