Creating DOS-bootable USB Flash Memory Device This information provides instructions for creating a DOS-bootable USB flash memory device using the Intel Server Platform SR6850HW4 or SR4850HW4. This process depends on the BIOS and EFI correctly detecting both a USB floppy disk drive and the USB flash memory device.

CAUTION This process formats the media and deletes all content from the USB Flash Memory device. This process also requires you to detach hard disk drives from the server before beginning. Before beginning, backup data on all devices attached to the server and test the backup.



NOTE Devices from some manufacturers may not be compatible with this system. For a link to a list of tested hardware, see the Intel® Server Platform SR6850HW4 Tested Hardware and Operating System List.

Before Beginning To create a DOS-bootable USB flash memory device on the Server Platform, you need the following: ƒ Server Platform SR6850HW4 or SR4850HW4 ƒ USB floppy disk drive ƒ USB flash memory device ƒ Bootable DOS floppy disk that contains the files FDISK.EXE and FORMAT.COM Verify the following: ƒ Attach the USB flash memory device to a different computer to ensure it can be detected ƒ Attach the USB floppy disk drive to a different computer to ensure it can be detected ƒ Make sure the floppy disk drive can boot to the bootable floppy disk that contains the FDISK.EXE and FORMAT.COM files ƒ Make sure the FDISK.EXE and FORMAT.COM files will successfully partition and format a hard disk drive.

CAUTION This process formats the USB flash memory device and deletes all content from the drive. Remove all media from the Server Platform: ƒ Disconnect/remove all hard disk drives ƒ Make sure the CD-ROM/DVD-ROM drive does not contain a disk

6. You will see the System Options Menu shown below.

7. Use the down arrow key to select “Boot Manager”. Press . 8. Review the Boot Option Menu for the list of boot devices. In the example below, both the USB floppy disk drive and the USB flash memory device are detected. These are the TEAC* FD-05PUB 1026 and the IOMEGA* Mini128MB+IOM2B52.00. If the devices are not detected, see “Troubleshooting a USB Flash Memory Device”.

9. Insert the bootable floppy disk into the USB floppy disk drive. 10. Using the arrow key select the USB floppy drive. Press . The system will boot to the floppy disk. 11. After DOS is booted, type FDISK and complete the following operations: 12. Delete existing partitions 13. Create a new partition 14. Make sure the partition is active 15. Reboot 16. After the system rebooted to the floppy disk, type FORMAT C: /S/U to format the created partition 17. Reboot the server. 18. Enter the System Options Menu, as you did in step 5. 19. Select the “Boot Manager”. Press . 20. Select the USB flash memory drive as the boot device. The system boots to DOS on the USB memory device.

Troubleshooting a USB Flash Memory Device Problems detecting the USB flash memory device: 1. Check to see if the USB flash memory device is displayed in the Boot Maintenance Manager. 2. Make sure the USB Flash memory device is correctly inserted into the USB connector and reset the server. Do not remove the USB Flash Memory while the system reboots and check the boot Manager again. 1. Create a small FAT partition (less than 64MB) on a system that is running the Windows* XP operating system. 2. Format the partition as FAT. 3. Reinstall the USB flash memory device into a USB port on the Server Platform SR6850HW4 or SR4850HW4. Boot the Server Platform to the DOS disk in the USB floppy drive. 4. Use DOS FDISK to delete all of the partition and create a small partition for DOS – make sure the partition created is set to “active”. 5. Power cycle the server. 6. Remove all other bootable media from the server. Problems booting to the USB flash device that has a partition and is formatted correctly: 1. Run FDISK /MBR 2. Make sure the partition is active. 3. Make sure the partition has been correctly formatted as a bootable partition. 4. Use the Boot Manager to select the boot device.



NOTE The USB flash memory device will only be present in the Boot Manager only while it is plugged in. Once the USB flash device is removed and the system is rebooted the USB flash memory device will no longer be seen in the Boot Manager.

The system boots to EFI when trying to boot to a USB floppy disk drive or to the USB flash memory device: This is typically an indication that no key was pressed when prompted to enter the System Option Menu or that the first boot device is EFI. 1. At the EFI Shell command prompt type EXIT to return to the System Option Menu. 2. Select “Boot Manager” 3. Select the correct boot device. The server has a SCSI hard disk drive and a USB flash memory device installed: The SCSI hard disk drive is the set as the first “Legacy HardDisk Drive” in the Legacy Hard disk Drive Order. The order can be changed as follows:
