Two- and four-columned stands for holding vehicles aloft during dismantling include A-frame style structures having no raised horizontal cross members. The stands have improved stability and safety for dismantlers and equipment operators in the work area and provide clear access to vehicle components. Preferred stands permit adjustment to the width of the stand at the top. Distance along the length of four-columned stands can be varied to accommodate vehicles of differing lengths, or height of the stand can be adjusted. Four-columned stands include a pair of two-columned stands, each of which is wider at its ground-level base than at the top, and two horizontal ground-level links that connect the two-columned stands at their bases. Preferably a top platform of each two-columned stand includes two horizontal sliding T-beam assemblies that contact portions of a mounted vehicle and also permit width adjustment. T-beam assemblies are mounted on top of diagonal column assemblies and the two resulting structures are firmly attached to opposite ends of a horizontal ground-level base plate. A height adjustment assembly, having a vertical adjustment tube and vertical extendable column, may be incorporated into diagonal column assemblies.

Disclosed is a personal computer system which includes a central processing unit (CPU) coupled to a direct access storage device (DASD) and a random access memory (RAM). A flash memory module is coupled to the CPU and an input/output (IO) bus and includes a basic input output system (BIOS) stored therein. The BIOS is effective for responding to the energization of the computer system by initiating a power on self test (POST). The BIOS is further operative on completion of the POST for transferring a portion of BIOS from the module to the RAM and for transferring control of the of the computer system to the BIOS portion. The portion of BIOS is operative to load a protected mode operating system (OS) into RAM and transfer control to the OS. The system further includes a logic circuit coupled to the flash memory module and the IO bus for allowing the BIOS in flash memory to be accessed while the protected mode OS is running.

A personal computer is BIOS configured to boot from an installed CD-ROM storing multiple operating systems in different partitions of the medium. The computer is initially booted from a user selected or default partition emulating a logical drive. With the original boot partition maintained active, emulation of additional partitions as other drives is performed when needed. This is accomplished in BIOS with multiple device tables, each dynamically associated with a logical drive letter. Hence, the system files found in only the original boot partition remain available to the system when other logical drives are called.

Bios dynamic emulation of multiple diskettes from a single media

In a computer operating a bootable CD-ROM or other bootable media having the capability of emulating one or more real drives, BIOS emulation parameters, such as drive number, memory partitioning and mapping are moved from BIOS and stored in a protected region of main memory. Upon a change of media, e.g., hard file, diskette, etc., as the computer undergoes a warm boot with new BIOS emulation parameters to enable DOS to process the change, the protected region of memory is not cleared. This preserves the BIOS emulation parameters which are restored to BIOS for the remainder of the boot sequence.

BIOS emulation parameter preservation across computer bootstrapping

A personal computer is BIOS configured to boot from an installed CD-ROM having at least one bootable partition. To enable swapping of large amounts of data stored on the CD-ROM at the BIOS level after the initial boot, the DOS-BIOS interface is modified so that a CD-ROM emulated as a hard drive file will emulate a floppy diskette image, a medium permitted by the operating system to be changed following an initial boot.

Bios emulation of a hard file image as a diskette

Multiple applications or versions of an application in different languages are distributed on a single mass storage medium, such as a CD-ROM. The BIOS is programmed to emulate different drives individually or simultaneously with data read from prescribed regions of the CD-ROM. To prevent access to unauthorized emulated images, each image is provided with an encryption key used as the seed to a pseudorandom number generator. Pseudorandom decryption of each block of data read from the CD-ROM is performed at the BIOS level only or at both the BIOS and application levels. For enhanced security, the algorithm decrypts each block of encrypted image data at a starting index that is pseudorandomly derived.

A optical input device which can determine the location of a stylus in a field with only a single emitter and a single detector. A fiber-optic bundle is used to transmit energy from the emitter to the vertical and horizontal output sides of a bezel. The fiber-optic bundle returns energy from the input vertical and horizontal sides of the bezel to the detector. The bezel is covered by LCD masks which block energy transmission through the bezel. A multiplexor scans the LCD masks to allow a beam of energy to scan across the vertical and horizontal fields of the device. The location of a stylus is located by detecting an interrupted beam.

Touch panel display

A system which can control a plurality of opto-matrix input devices. Each opto-matrix device uses multiplexed scanning of emitter/detector pairs under control of a separate computer. The output of the opto-matrix input device is analog data which is provided to the computer for conversion to digital by the computer. The computer then determines if a stylus is located in the opto-matrix field, and if so, determines the stylus location by analysis of the received data.

A computer system and method for operating a computer system capable of running in mutually incompatible real and protected addressing modes, in which programs written for one mode can be run in the other mode without modification. The BIOS assembles two different common data areas for the two modes, each inclusive of device block pointers, function transfer table pointers, data pointers, and function pointers. The common data area for the real mode is assembled first. To assembly the pointers for the protected mode common data area, the offset values from the real mode area ae copied directly, and then selector values are inserted whose physical addresses correspond to the segments of the corresponding pointers in the real mode area. The selector values are derived from a segment descriptor table.

The operating system using BIOS assembles two different common data areas for the two modes, each inclusive of device block pointers, function transfer table pointers, data pointers, and function pointers. The common data area for the real mode is assembled first. To assemble the pointers for the protected mode common data area, the offset values from the real mode area are copied directly, and then selector values are inserted whose physical addresses correspond to the segments of the corresponding pointers in the real mode area. The selector values are derived from a segment descriptor table.

A door lock for door structures such as used in buildings includes a U-shaped clamp member having an elongated hook portion adjustably supported longitudinally on one leg thereof. An angle plate with a hook receiving right is secured by screws to the door. The U-shaped clamp member is positioned about three sides of an upright post that forms part of the frame of the door structure so that the hook member projects laterally outwardly from the fourth side of the upright post for engagement with the hook receiving right. With the hook and ring engaged, the locking member is movable downwardly into biting engagement with the post to positively secure and hold the door against the door frame.
