		+
		+	Format usb drive as vfat, and bootable
		+
		+	<pre>
		+	# fdisk /dev/sdb
		+
		+	Command (m for help): n
		+	Partition type:
		+	p primary (0 primary, 0 extended, 4 free)
		+	e extended
		+	Select (default p): p
		+	Partition number (1-4, default 1): 1
		+	First sector (2048-3780607, default 2048):
		+	Using default value 2048
		+	Last sector, +sectors or +size{K,M,G} (2048-3780607, default 3780607):
		+	Using default value 3780607
		+
		+	Command (m for help): p
		+
		+	Disk /dev/sdb: 1935 MB, 1935671296 bytes
		+	60 heads, 62 sectors/track, 1016 cylinders, total 3780608 sectors
		+	Units = sectors of 1 * 512 = 512 bytes
		+	Sector size (logical/physical): 512 bytes / 512 bytes
		+	I/O size (minimum/optimal): 512 bytes / 512 bytes
		+	Disk identifier: 0x000456be
		+
		+	Device Boot Start End Blocks Id System
		+	/dev/sdb1 2048 3780607 1889280 83 Linux
		+
		+	Command (m for help): t
		+	Selected partition 1
		+	Hex code (type L to list codes): b
		+	Changed system type of partition 1 to b (W95 FAT32)
		+
		+	Command (m for help): a
		+	Partition number (1-4): 1
		+
		+	Command (m for help): p
		+
		+	Disk /dev/sdb: 1935 MB, 1935671296 bytes
		+	60 heads, 62 sectors/track, 1016 cylinders, total 3780608 sectors
		+	Units = sectors of 1 * 512 = 512 bytes
		+	Sector size (logical/physical): 512 bytes / 512 bytes
		+	I/O size (minimum/optimal): 512 bytes / 512 bytes

		+	/dev/sdb1 * 2048 3780607 1889280 b W95 FAT32
		+
		+	Command (m for help): w
		+	The partition table has been altered!
		+
		+	Calling ioctl() to re-read partition table.
		+
		+	WARNING: If you have created or modified any DOS 6.x
		+	partitions, please see the fdisk manual page for additional
		+	information.
		+	Syncing disks.
		+	</pre>
		+
		+	Format has vfat
		+
		+	mkfs -t vfat /dev/sdb1
		+
		+	Re-insert the usb drive and mount the vfat partition
		+
		+	Find and download netinstall image from lastest Centos 5 release.
		+
		+	wget http://SERVER/centos/5.8/isos/x86_64/CentOS-5.8-x86_64-netinstall.iso
		+
		+	Install unetbootin:
		+	yum install unetbootin
		+
		+	Use unetbootin to install this image onto
		+
		+	Diskimage: CentOS-5.8-x86_64-netinstall.iso
