#PHOENIX AWARDBIOS CMOS SETUP UTILITY PRIORITIZE ONBOARD SOFTWARE#
Note 1: When you leave a non-bootable USB drive connected at boottime, the booting process could stop with a message “Non-system disk or disk error, Press any key” or whatever similar message was written to that drive by the software that FORMATted it. The boot setting for this system should be: The USB drive does occur in that sequence, but with a lower priority than the SATA drive. If all three fail, and only if Boot Other Device is Enabled, the BIOS tries its own additional sequence of Boot Devices. So it seems that this BIOS first tries to boot from the configured Boot Devices. » When the USB stick is not connected, the system boots from SATA † When the USB stick is not connected, booting fails So now for a number of tests with the SATA interface enabled: Boot Other Device
So it appears that there are two ways that allow booting from USB: you can select USB-ZIP as a Boot Device or set Boot Other Device to Enabled. The USB stick was the only USB storage device connected, there was no disc in the CD-ROM drive. To see with what settings the system can boot from USB stick, I took some tests with a disabled SATA interface. The test system is equipped with a SATA harddisk.
This screen is only relevant when you want this system to boot from USB harddisk. Last there is a screen called “Hard Disk Boot Priority”. Next there is a setting called “Boot Other Devices”, which can be Disabled or Enabled: This BIOS offers many options for a Boot Device, but unfortunately there is neither a “USB-memorystick” or a “USB-HDD” setting. The three most logically related are called “First Boot Device”, “Second Boot Device” and “Third Boot Device”. In this BIOS there are multiple settings related to booting.
