Q1: How to confirm whether my motherboard support ASUS EZ Flash 3?
A1ASUS EZ Flash 3 only applicable to UEFI BIOS motherboards with built-in ASUS EZ flash 3, you can confirm the product specifications from the official website.
In you bios menu, when you pick the boot priority, you have the option to chose between USB, HDD and FDD drives. However, additionally, you can select the HDD to boot from in a separate menu on the boot menu page. Go into that menu, and check if your USB stick is listed next to the HDD drives in your system.
When it eventually reboots again after flashing, it will have probably changed most of your EFI settings (such as your memory XMP profile, resizable BAR and so on), so press Del to enter the EFI again and get your settings right. You should be able to check that your motherboard is indeed running the latest version from here too, but if not, run CPU-Z when you get into Windows, and click on the Mainboard tab. Your new BIOS version number (F24 in our case) should be listed in the BIOS section, along with the date of issue.
Booting Linux from USB-ZIP: If you have an older computer system, your BIOS might not support USB-HDD boot. In this case, it may still be possible to boot Linux from USB if your BIOS does list USB-ZIP as a boot option. In order for this to happen, we need to trick the BIOS into thinking that the USB flash drive is a zip drive.
We can trick the BIOS by modifying the number of heads and sectors being displayed from the USB flash device to match that of a zip drive. Then we partition the drive using partition 4 (the partition that zip drives typically use). For this tutorial we will use the mkdiskimage application that comes with syslinux.
Linux distributions running GNOME can easily make a live CD through nautilus and gnome-disk-utility. Simply right-click on the .iso file, and select Open With Disk Image Writer. When GNOME Disk Utility opens, specify the flash drive from the Destination drop-down menu and click Start Restoring.
It does not require creating a EFI system partition on the drive as all UEFI will happily boot any FAT volume from USB flash drives. The most compatible setup would be using the MBR partition table with a single active (bootable) primary partition of type 0c "W95 FAT32 (LBA)".[3]
I have this old desktop: dell deminsion c521. I made a bootable linux usb with rufus. It detects it in the bios as "usb zip" however when I try to boot from it I get a flashing underscore. Ik it works because it works on my normal desktop and I'm sure that my boot priorities are correct. Suggestions?
To make a flash Drive boot able, I would suggest using a Win9X Boot floppy or CD which you can get from and then make the flash drive as one of the boot options in your BIOS then use FDISK and FORMAT to create and format the partitions.
This is a feature on the mainboard that protects the BIOS from being flashed accidentally. It is called BIOS flash protection. Please disable this function with either a hardware jumper setting or with the CMOS Setup Utility. Please refer to the manual for more details on how to disable flash protection.
I have an Asus h81 gamer motherboard, when I start the computer when loading the bios, when I want to press default settings, I want to save it with f10, right after that the uefi bios freezes, then after resetting rtc it does the same thing.I would like to ask how can I update the motherboard bios again and how can I make a bootable flash usb disk if I have already managed to format the usb device to the fat32 file system.?
When you try to copy the files from the firmware directory to the bootable USB drive, you will be prompted to replace AUTOEXEC.BAT. Make sure to Replace the file in the destination as this will execute the command to launch the flash2 utility, which actually writes the firmware to the device.
If the motherboard itself is bricked, you would have to flash the chip itself; which is outside the scope of this. You might be able to find an already programmed bios chip on ebay; that would likely be your best bet.
Note - If you use the SIA USB flash drive for operating system installation, oncethe OS is initially installed from OS distribution media on the server harddisk, a reboot is required to finish the installation. At that point, theUSB flash drive must be either unplugged or its boot priority lowered inthe BIOS settings to ensure the server boots from the hard diskto finish the installation.
"Some USB flash drives are notorious for having problems with corrupted master boot records. If your system refuses to boot from the flash memory stick, the mbr may be at fault. To fix this, you can use the mbr package to install a new master boot record. " www.pendrivelinux.com/install-a-new-mbr-to-your-usb-flash-device/#more-191
A USB flash drive can store important files and data backups, carry favorite settings or applications, run diagnostics to troubleshoot computer problems or launch an OS from a bootable USB. The drives support Microsoft Windows, Linux, MacOS, different flavors of Linux and many BIOS boot ROMs.
Data on USB flash drives can be retained for long periods when the device is unplugged from a computer, or when the computer is powered-down with the drive left in. This makes a USB flash drive convenient for transferring data between a desktop computer and a notebook computer, or for personal backup needs.
What happens now depends on what the bootable USB device was intended for. If you're booting from Windows 11, Windows 10, etc. installation files on a flash drive, the operating system setup will begin. If you're booting from a DBAN flash drive you created, it will start. You get the idea.
7. When this process completes, the USB drive will be able to boot the machine into a DOS environment. This becomes a useful tool for running diagnostic software (Seatools, memtest, etc) or for flashing the latest BIOS. Depending on the model, the setting in the BIOS to choose in order to boot from a USB key is USB-ZIP or the manufacturer of the USB drive itself.
Alternatively, use a PC Card adapter for CompactFlash (available from approx. USD 10) with a CompactFlash card in a PC Card slot in your PowerBook G3 Series computer. The CF card could then be read in a modern Mac or PC (via a USB flash memory card reader). CF cards are typically PC-formatted (which should be OK for photo transfers), but can easily be reformatted, if necessary.
The reason why we need to boot computer from a USB flash disk is that sometimes booting from USB is necessary and convenient. For example, when the Windows gets damaged and it can't be logged in; meanwhile there is important data in the partition C so data will lose if you reinstall system; then it'll be a good decision if you boot the computer from a USB flash disk and copy data to another partition.
Booting from USB flash disk requires the computer support booting from USB devices (which is supported by most of the motherboards now). Operation steps are as follows: insert the USB flash disk to the USB slot ahead of powering on the computer; then press the key "Del" and enter the BIOS setup; enter Advanced BOIS Features and set first boot device as USB-ZIP or USB-HDD; save and set the BIOS setup and the computer will boot from the USB flash disk.
If you have a new computer model (usually with Windows 8 or Windows 10) that has UEFI/EFI, make sure that you read UEFI/EFI configuration before you proceed to How to boot from a USB flash drive below.
Rufus is a small utility that helps format and create bootable USB flash drives, such as USB keys/pendrives, memory sticks, etc. It can be be especially useful for cases where: you need to create USB installation media from bootable ISOs (Windows, Linux, etc.); you need to work on a system that doesn't have an OS installed; you need to flash a BIOS or other firmware from DOS; you want to run a low-level utility. Rufus is significantly faster than similar utilities and it's open source and free.
