GT2 Mega,IT15,GT15 Max BIOS Setup Instructions

Includes Three Operating Modes：Silent Mode,Normal Mode,Performance Mode.

The BIOS operating mode mainly affects the CPU’s power limit (performance output) and the corresponding fan speed.

In Silent Mode, the CPU power consumption is reduced, and the fan speed is lowered accordingly.

In Performance Mode, the system maintains a higher CPU power limit, delivering smoother performance when running high-load applications.However, this will also result in increased fan noise.

The Scheduled Power On feature allows the system to automatically boot up at a specific time and frequency (Daily or on a specific Date).

Expanded Insight:

• This feature, also known as “Power On By RTC” or “Resume by Alarm”, is useful for scheduling tasks such as automatic backups, updates, or starting work in the morning without manual intervention. Enabling this can save time but requires the system to be connected to power and in a soft-off state .

This setting determines the system's behavior when AC power is restored after an unexpected power failure.

Expanded Insight:

• If set to Always On, the device will reboot immediately once electricity returns. This is a critical setting for remote servers or home labs where manual intervention is difficult.

• This is essential for unattended systems like servers or NAS to ensure availability after power failures.

Boot Priority defines the order in which the BIOS searches for an operating system across available storage devices.

Expanded Insight:

• The default prioritizes the internal system disk (SSD/HDD) for fast normal booting. You can adjust it to boot from USB, optical drive, or network (PXE) first, which is useful for system recovery, installation, or diagnostics. Changing this order allows flexible booting options but incorrect settings may prevent normal startup.

• When updating the BIOS or reinstalling the system, this option does not need to be changed.

Secure Boot is a security standard that ensures a device boots using only software that is trusted by the Original Equipment Manufacturer (OEM).

Expanded Insight:

• This prevents rootkits and unauthorized operating systems from loading during the boot process. Note that some older Linux distributions or legacy hardware may require this to be disabled.

• It helps protect against malware, rootkits, and unauthorized bootloaders. While it enhances system security, it may interfere with custom OS installations (like certain Linux distros) or require disabling for legacy software.

Wake-on-LAN (WoL) allows a computer to be turned on or "woken up" by a specific network signal sent over the local area network.

Expanded Insight: 

• It is widely used by IT administrators for remote maintenance or by power users who need to access their home PC via the internet through a gateway.

• Wake-on-LAN enables the computer to be woken up from sleep or shutdown state remotely by sending a special “magic packet” over the local network. This is convenient for remote access, file sharing, or managing the PC from another device. Note that it consumes a small amount of standby power.

This function manages the cooling fan's rotation speed based on the internal temperature of the chassis and CPU.

Expanded Insight: 

• In Auto mode, the system balances noise and cooling. 

• Other options may include Silent (lower speeds for quiet operation), Standard, or Performance (higher speeds for better cooling under load). It directly impacts noise levels and component temperatures.

Set BIOS Password restricts access to the BIOS settings (Supervisor Password) or the boot process itself (User Password).

Expanded Insight: 

• This adds a layer of physical security, preventing others from changing hardware configurations or overriding boot priorities.

• It prevents unauthorized changes to critical settings, enhancing security especially on shared or public computers.
