BIOS Interface and Navigation

Accessing the BIOS

The PowerEdge T30 BIOS can be accessed through three primary methods:

• Physical Access: Press the F2 key during the initial power-on sequence (POST).
• Remote Access: Use iDRAC8 (Integrated Dell Remote Access Controller) via HTTP/HTTPS or SSH.
• OS Integration: Access BIOS settings through the Dell Server Configuration Utility (SCU) or Dell PowerCenter.

Note: The iDRAC8 interface requires an admin account with password authentication. For remote management, ensure the network cable is properly connected and the iDRAC8 service is running.

BIOS Main Menu Structure

The BIOS interface is organized into the following sections:

1. System Configuration
2. Boot Settings
3. Hardware Settings
4. Power Management
5. Security Settings
6. Virtualization Settings
7. Diagnostics
8. Save & Exit

Each section contains submenus with configurable parameters. For example, under Boot Settings, you can adjust boot order, enable Legacy/UEFI mode, and configure PXE (Pre boot Execution Environment).

Core BIOS Startup Options

1 Boot Order Configuration

The boot order determines the sequence in which devices are attempted to boot the operating system. Incorrect boot order can lead to delays or failure to boot from intended media.

Configuration Steps:

1. Navigate to Boot Settings > Boot Order.
2. Highlight the desired boot device (e.g., "Hard Disk," "USB Device").
3. Use the Up/Down arrow keys to adjust its position in the list.
4. Press F10 to save changes.

Best Practices:

• Prioritize bootable media (OS installation USB, recovery drive) at the top of the list.
• Place non-bootable devices (CD-ROM, secondary硬盘) at the bottom.
• For servers with multiple storage controllers, ensure redundant boot devices are configured.

Example Scenario: If you need to boot from a USB installation media repeatedly, assign it as the first boot device. For production systems, set the primary硬盘 as the default boot target.

2 Boot Mode Selection

The PowerEdge T30 supports both Legacy BIOS (for Windows Server 2008 and earlier) and UEFI (Unified Extensible Firmware Interface) modes.

Configuration Steps:

1. Go to Boot Settings > Boot Mode.
2. Select UEFI or Legacy based on your OS requirements.

Key Differences:

Feature	UEFI	Legacy BIOS
Support	Windows 8/10/11, Linux (most distros)	Windows Server 2008, older OS
Secure Boot	Enabled by default	Not supported
Storage Support	NVMe, SATA, M.2	Basic IDE/SATA

Recommendation: Use UEFI mode for modern operating systems and Secure Boot to prevent unauthorized firmware. For legacy systems, Legacy BIOS remains an option.

3 PXE Network Configuration

PXE allows the server to boot from a network-based installation server (e.g., Windows Deployment Services or kickstart servers).

Configuration Steps:

1. Navigate to Boot Settings > PXE Setup.
2. Enable PXE Rom Load to allow network booting.
3. Set PXE优先级 to "High" if network booting should take precedence over local devices.

Common Issues:

• MAC Address Conflict: Ensure the server's MAC address is unique on the network.
• DHCP Configuration: Verify the DHCP server is configured to provide boot files (e.g., undionetboot.cpi).

4 BIOS Boot Partition Configuration

For UEFI systems, the BIOS Boot Partition (ESP) is required for booting from USB or network media.

Configuration Steps:

1. Use Dell System Update or DRAC8 Web Interface to create an ESP.
2. Assign the partition ID ( typically EFI) to the ESP.

Note: If the ESP is missing, the server may fail to boot from non-hard-disk devices.

Hardware Initialization Settings

1 CPU Configuration

The T30 supports up to two Intel Xeon E-2100 series processors (e.g., E-2180).

Key Parameters:

• Hyper-Threading: Enable for improved multi-core performance.
• Intel Turbo Boost Technology: Set to "Unrestricted" for maximum clock speed.
• Power Limit: Adjust based on thermal constraints (e.g., 100W for sustained loads).

Recommendation: For compute-heavy workloads, enable all cores and set Turbo Boost to "Unrestricted."

2 Memory Configuration

The T30 supports up to 512GB DDR4 memory (16 DIMM slots, 32GB per slot).

Critical Settings:

• Memory Mode: Set to "x4" for maximum bandwidth.
• Voltage: Adjust to 1.35V for DDR4-2400 speeds.
• ECC Support: Enable for data integrity in mission-critical applications.

Diagnostic Tool: Use Dell Memory Diagnostics (available via iDRAC8) to test RAM before OS installation.

3 Storage Controller Settings

The T30 uses the PERC H330 (SAS/SATA) or H730 (RAID) controller, depending on the model.

Configuration Steps:

1. Access Hardware Settings > Storage.
2. Set RAID Mode to "AHCI" for basic functionality or "RAID 10" for performance.
3. Enable Hot Swap Support for redundant drive removal.

Important: For RAID configurations, ensure the controller firmware is updated to the latest version.

4 Network Interface Card (NIC) Settings

The T30 typically includes one or two Intel Ethernet i350-T1 (10GbE) NICs.

Key Parameters:

• Speed/Duplex: Set to auto-negotiate unless manually configured.
• Jumbo Frames: Enable for large data transfers (e.g., 9216 bytes).
• Teaming: Configure for link aggregation (requires two NICs).

Best Practice: Use Team Policy to distribute traffic across multiple NICs and improve throughput.

Security and Authentication

1 BIOS Password Protection

Prevent unauthorized access by requiring a password to enter or change BIOS settings.

Configuration Steps:

1. Go to Security Settings > System Password.
2. Set a complex password (12+ characters, mix of letters/numbers/symbols).
3. Optional: Enable Power-On Password to require authentication at startup.

2 Secure Boot Configuration

UEFI Secure Boot ensures only signed firmware and OS images are allowed to boot.

Configuration Steps:

1. Navigate to Security Settings > Secure Boot.
2. Enable Enable Secure Boot.
3. Add trusted certificates or manufacturer keys (e.g., Microsoft, Dell).

Impact: Prevents boot attacks like boot sector viruses. May require OS vendor signature updates.

3 Virtualization Technology Enablement

For virtualization platforms like VMware, enable CPU virtualization extensions.
