Abstract:
A backup system on an external bootable personal computer drive that presents a unique and specific wall paper display on the computer monitor when the operating system residing on the drive is booted when the drive is externally attached to the computer system. The invention is used to make it obvious to the user that the original system drive has been replaced by a cloned or imaged drive. The invention consists of a software program and a graphics file. The software program recognizes the case where the drive it resides on has been booted over an external bus and when that event occurs the software program substitutes a specific graphic file for the normal wall paper file used to display the background on the computer display.

Description:
This application claims priority from provisional application No. 61/162,968, filed Mar. 24, 2009, the entire contents of which are herewith incorporated by reference. 
    
    
     BACKGROUND 
     Software programs that backup data from a personal computer onto some external storage have been utilized by computer users for a relatively long period of time. These software have progressed from simple file transfer utilities to where they now create compressed images of the data to be backed up to creating bootable backup drive[s] that are cloned images or bootable versions of the system drive. The CMS products “bounce back” software for example can create both cloned images and bootable versions of the system. 
     These software programs use many methods of restoring the system drive if the system drive becomes unbootable or corrupted due to any number of reasons such as virus attacks or psychotic software destroying files and operating system programs. Otherwise, restoration or rebuilding of the system disk can take many hours to complete which is not a desirable operation when access to a computer is critical. 
     A second method which is relatively recent in concept and ability is to boot from an attached imaged backup drive. The ability to perform this type of boot has only been available since approximately 2008. Prior to this time, most BIOS&#39; of personal computers did not support booting from external devices that are attached to the personal computer through other than a system bus. 
     External booting presents a number of challenges to the user with the first being able to actually create a bootable drive. Typically external bootable drives are difficult to create. 
     SUMMARY 
     Once an external bootable drive is created, the inventors recognize that it is desirable to alert a user that the external drive is the boot drive. 
     Users have confused the internal system drive with an external drive. At the present time, there is no way that a cloned or imaged system drive can make itself known to the casual user of a computer system if it was booted from an external drive. 
     An embodiment describes a computer system which alerts a user about whether the system drive is a cloned or image of the original system drive and is externally attached to the computer system. 
     In one embodiment, the imaged system drive will, upon being booted, present the user with a unique wall paper display such that is prominent and makes it difficult for the user to mistake the origin or location of the system drive. 
     In another embodiment, the software restore program will, if the user directs the software to restore the system drive from the booted attached drive, restore the user&#39;s original wall paper display. 
     In a third embodiment, the software will, if the user replaces the internal system drive with the externally attached drive, restore the user&#39;s wall paper display at boot time. 
     While the novel features of the invention are set forth particularly in the appended claims, the invention, both as to organization and content, will be better understood and appreciated, along with other objects and features thereof, from the following detailed description taken in conjunction with the drawings.

     DETAILED DESCRIPTION 
     In the following, preferable embodiments of the present invention are described by referring to the drawings. Embodiments of the present invention are illustrated by way of example, and not by way of limitation. In the figures, the same reference numerals designate the same or corresponding parts throughout the different views, and redundant explanations may be omitted. 
     Now referencing the drawings, more specifically  FIG. 1  where  10  is a schematic representation of a typical personal computer system. The personal computer system  11  contains system bus  12 , micro processor  13 , system memory  14 , system BIOS  15 , system drive interface  16 , and external peripheral controller  17 . Internal disk drive  19  is the normal system boot drive and external storage device  20  is the backup storage device attached external peripheral controller  17  through external bus  18 . 
     Under normal operation, that is where no problems exists, selection of internal disk drive  19  as the boot device is made by system BIOS  15  at system reset time or system power on time. Normally, the operating system for personal computer system  11  will be booted from internal disk drive  19 . After the boot sequence is complete, the user will at some point in time connect or attach external storage device  20  and cause backup restore software  31  to be executed. Backup restore software  31  will partition and format external storage device  20 . External storage device  20  may be any of a plurality of attachable storage devices such as rotating magnetic hard disk drives, flash memory thumb drives, compact flash drive, or any other storage device of sufficient size to contain all of the data and software held on internal disk drive  19 . 
     External storage device  20  is attached to personal computer system  11  through external bus  18  and external peripheral controller  17 . External peripheral controller may be any of a plurality of external peripheral controllers such as USB controller, IEEE-1394 controller, E-SATA controller, Express Card controller, Ethernet controller, 802.11 wireless controller, or any other commonly used external peripheral controller used to connect external devices to a personal computer system bus. 
     When external storage device  20  is initially attached to personal computer box  11 , backup restore software  31  will be, under user direction, be loaded into system memory  14  and executed. Backup restore software will partition external storage device and create a master boot record and other data structures necessary to allow external storage device  20  to be a bootable device. 
     Now referencing  FIG. 3  where  50  depicts the master boot record and volume boot sectors. The master boot record or MBR, is depicted as  51  and the volume boot sectors as  60 . MBR  51  is the first sector or sector address  0  on a storage device. The MBR  51  is 512 bytes in length. MBR  51  typically contains 440 bytes of machine instructions that can determine of disk partition  1  parameter  55  points to (is an address pointer) a valid partition on the device and if partition  1  contains an operating system. If disk partition  1  parameter  55  references a partition with a valid operating system, that reference will point to the first of a series of sectors referred to as volume boot sectors  60 . Within these sectors is disk parameter block  61  and volume boot code  62 . Boot code area  52  will read volume boot sectors  60  from the same storage device into system memory and transfer processing control to volume boot code  62 . Volume boot code  62  contains intelligence of the file system used to manage storage device on which it resides. Volume boot code  62  will find the operating system through the file system and read a sufficient amount of the operating system into the system memory and transfer control to it. 
     After building master boot record  51  on external storage device  20 , backup restore software  31  will transfer all data and program files from internal disk drive  19  to external storage device, one file or one file part at a time. This method of moving whole files from one storage device to another has 2 major side benefits as opposed to performing a bit by bit copy of internal disk drive  19  to external storage device  20 . First, the external storage device file structure will be a defragmented version of that found on internal disk drive  19 . Any problems with the directory structure found on internal disk drive  19  will not be replicated on external storage device  20 . Also, the external storage device  20  may be larger than internal disk drive  19 . Any time after backup restore software  31  has transferred the software and data from internal disk drive  19  to external storage device  20 , the user will be able to boot from external storage device  20 . 
     If internal disk drive  19  fails and becomes unbootable, the external drive can be used as the new boot drive. Depending on system BIOS  15 , the user may need to alter the boot settings during boot time. System bios  15  typically contains a block of user interface code that can be invoked by the user holding down some predetermined key on the system keyboard while the system is being booted. During the bios boot process, system BIOS  15  will check to see if the predetermined key is being depressed by the user. If the key is depressed, system BIOS  15  will begin executing the user interface. Among the options the block of user interface code provides is the ability of the user to change the behavior of the boot sequence such that system BIOS  15  will either attempt to boot from internal disk drive  19  or external storage device  20 . Any of these storage devices may be selected as the first boot device or the second boot device. 
     A purpose behind allowing different storage devices to be selected as the first, second, or third boot device is to provide for the case where the primary boot device is defective or the user wants to boot from a device other than the system drive. Once a boot device has been selected as the primary boot device, the boot sequence is essentially the same, regardless of the actual device containing the boot code. 
     Once the user has reset the boot order such that internal disk drive  19  is the primary boot device, an external storage device  20  becomes the second boot device. If system BIOS  15  cannot complete a boot sequence from internal disk drive  19 , it will, after some predetermined period of time, initiate a second boot sequence from external storage device  20 . 
     After the boot sequence has been completed from external storage device  20  and the operating system is running, the normal desk top wall paper  40  as shown in  FIG. 4  will be replaced with rescue wall paper  41  shown in  FIG. 5 . Backup restore software  31  changes the system pointer for the desktop wall paper for the system variables contained on external storage device  20  from normal desktop wallpaper  32  (depicted as normal desk top wall paper  40  in  FIG. 4 ) to external boot background wallpaper  33  (depicted as rescue wall paper  41  in  FIG. 5 ). This change in wall paper alerts the user in a very graphic manner that personal computer system  11  is running off of external storage device  20 . 
     In this description, the word “wallpaper” refers to any kind of screen which is shown from the operating system to the user. A conventional wallpaper might include the entire background shown as the background for the complete screen.  FIG. 4  shows the complete background for the complete screen as wallpaper  40 . However, wallpaper may alternatively be on only a portion of the screen, or maybe for example special kinds of icons on the screen. For example, in certain versions of the Windows operating system, the wallpaper covers only portions of the screen, with other portions of the screen reserved for items like toolbars, task bars, and/or widgets. All of these are intended to be included within the term “wallpaper”. 
     In one embodiment, the wallpaper covers the background of substantially the entire viewable area of the screen other than toolbars and widgets. 
     If the user wants to restore the software and data on internal disk drive  19  or replaces internal disk drive  19  with a fresh disk, the user can invoke backup restore software  31  from external storage device  20 . When this happens, external storage device  20  will partition internal disk drive  19  and create a master boot record and other data structures necessary to allow internal disk drive  19  to become a bootable device. After this procedure has completed, the user may initiate a reboot sequence and system BIOS  15  will boot from system drive  16 . Then, the reboot sequence again automatically changes the wallpaper pointer so that the wallpaper reverts back from the special wallpaper  41  to the original wallpaper  40 . 
     If external storage device  20  contains a compatible disk drive that can be placed into personal computer system  11  and connected to system drive controller  16  the user can choose to perform this action and reboot the system. Once the system has been rebooted from the new internal disk drive  19 , backup restore software  31  will, the first time it is executed, restore the system pointer for the desktop wall paper for the system variables contained on internal disk drive  19  from external boot background wallpaper  33  (depicted as rescue wall paper  41  in  FIG. 5 ) to normal desktop wallpaper  32  (depicted as normal desk top wall paper  40  in  FIG. 4 ). 
     According to embodiments, either or both drives can operate according to USB specifications; IEEE 1394 specifications; ESATA specifications or any other. The drive can be connected over an Ethernet network. The first external bus can be a PCMCIA bus or a PC Express bus. The first external bus can be an implementation of a wireless network such as:

     Although only a few embodiments have been disclosed in detail above, other embodiments are possible and the inventors intend these to be encompassed within this specification. The specification describes specific examples to accomplish a more general goal that may be accomplished in another way. This disclosure is intended to be exemplary, and the claims are intended to cover any modification or alternative which might be predictable to a person having ordinary skill in the art. For example, other ways of indicating the fact that a backup drive is being used may be contemplated according to the present system. For example, instead of using wallpaper which covers substantially all of the background, an icon can be used. In addition, while the wallpaper described above includes a different picture, it can automatically change the color of the existing wallpaper, for example to a complementary color. Another embodiment might display a wallpaper style icon across the entire existing wallpaper. 
     Those of skill would further appreciate that the various illustrative logical blocks, modules, circuits, and algorithm steps described in connection with the embodiments disclosed herein may be implemented as electronic hardware, computer software, or combinations of both. To clearly illustrate this interchangeability of hardware and software, various illustrative components, blocks, modules, circuits, and steps have been described above generally in terms of their functionality. Whether such functionality is implemented as hardware or software depends upon the particular application and design constraints imposed on the overall system. Skilled artisans may implement the described functionality in varying ways for each particular application, but such implementation decisions should not be interpreted as causing a departure from the scope of the exemplary embodiments of the invention.
