5. DIAGNOSTIC TEST OPERATION
Method 2: Formatting the USB memory on Linux
The operation below is in the case that the USB memory is assigned with /dev/sda1.
This operation is performed on the Linux installed into the PC. Also it can be executed on 1CD-Linux such
as KNOPPIX. The following operation is performed when any another USB memory and USB floppy disk
drive are not connected to the Linux-based PC.
1.
Boot the Linux.
2.
Insert the USB memory into the USB slot.
3.
Type in the following command to declare the formatting the USB memory.
fdisk /dev/sda1
The device name (sda1) may differ when another USB memory or USB floppy disk drive is used.
4.
Deleting the current partitions
Execute p command to check the current areas, then execute d command to delete all areas as shown
below.
d (Deletion) → 1 through 4 (Area Number) (Repeat this step until all areas are deleted.)
5.
Creating a new area.
Type in the following commands from the keyboard to create a new area.
n (New)/p (Primary)/1 (Area Number)/[ENTER] (Start cylinder)/[ENTER] (End cylinder)
6.
Type in a command to put the flag "bootable", resulting in that Linux is bootable from the USB memory.
a (The flag "bootable" is put.)
7.
Changing the ID Number of the partition which is newly created
Type in the following commands from the keyboard to change the ID Number of the partition newly
created. (The area is set to ID Number 1 in FAT32 filesystem.)
t (Changing the ID Number of the area)/1 (ID Number)/b (FAT32 filesystem)
8.
Saving the area setting data
Type in w command from the keyboard to save the setting data, then terminate fdisk.
w (The setting data is written into the disk, then fdisk is terminated.)
9.
Formatting the partition in FAT32 filesystem
Type in the following command from the keyboard. (The area ID Number 1 of the device sda1 is
formatted in FAT32 filesystem supporting long file name.)
mkfs.vfat -n DIAGDSK /dev/sda1
10. Write the "mbr.bin" file included in the USB DIAG. kit onto the master boot record of the USB memory.
Type in the following command from the keyboard.
cat syslinux/mbr/mbr.bin > /dev/sda1
(2) Copying necessary files into the USB memory
Copy all the files stored in the folder "bootimage" into the USB memory. This folder is stored in the provided
USB DIAG. kit. This operation can be performed by a copy and paste on the Explorer, etc.
Copy the two folders (settings and setkbd) and the seven files (mvlinux, initrd.gz , usr.img.ext2, root.img.ext2,
syslinux.cfg, splash.png, and vesamenu.c32) stored in the folder "bootimage" into the USB memory.
