BIOS Setup
Fast BIOS Mode

- ● Fast Bios Mode
- Fast BIOS Mode is technology to reduce the boot up time by skipping the USB check in the POST stage.
→ DOS mode booting is not supported. (Basic ODD, USB memory devices, etc.)
- The factory default setting is [Disable]. When the purchase date is registered, the setting is automatically
changed to [Enable]. Once the setting is changed to [Enable], the default setting in the CMOS is changed to
[Enable].
◆ Problem: The system does not boot from a standard ODD or USB device (e.g. CD-ROM drive, memory device,
etc). (All models with the Fast BIOS Mode feature have this problem.)
◆ Symptom
- The system cannot boot from a standard ODD or USB device (e.g. CD-ROM drive, memory device, etc).
- When the system boots from a brand new HDD (with a clean MBR), the system reboots indefinitely in the POST
stage.
◆ Cause
- The system boots up faster by skipping the USB check operation.
◆ Solution
- The problem is resolved if [Fast BIOS Mode] is set to disabled in the CMOS Setup menu.
※ The factory default setting is [Disable]. When the purchase date is registered, the setting is changed to [Enable]
automatically.
