F Configuring Memory Introduction Computers handle information as strings of binary digits: ones and zeros. A single I or 0 is refer-red to as a bit, the smallest unit of information handled by the computer. A group of eight bits, referred to as a byte, is used to represent single characters or numbers such as "A" or "5". The si[...]

Configuring Memory This appendix describes the various areas of memory (RAM) and how you can make memory more efficient by configuring it in conjunction with the memory management device drivers supplied with your TravelMate 3000. F-2 Configuring Memory[...]

TravelMate 3000 Memory Areas MS-DOS directly accesses up to 640 KB of RAM for the execution of programs and commands and for storing temporary data. MS-DOS cannot directly access memory beyond this 640-KB limit . The amount of standard default RAM (640 KB) in the TravelMate 3000 is displayed on the Setup Program menu as Standard (Memory), and it ca[...]

TravelMate 3000 Memory Areas Extended Memory Extended memory is internal RAM above 1024 KB. MS-DOS cannot directly access Extended memory as system memory, but the memory can be configured as one or more RAM disks. It can also be accessed by application programs specially written to use Extended memory. The HIMEM.SYS device driver described later i[...]

TravelMate 3000 Memory Areas Before you can use Expanded memory, you must install the EMM.SYS device driver as described in the next section, "Memory Device Drivers." You need not install the Expanded memory driver if your application program does not support use of Expanded memory. Configuring Memory F-5[...]

Memory Device Drivers The following four device drivers are provided to manage the TravelMate 3000 memory: q EMM.SYS - device driver supports LIM-EMS Expanded memory. q HIMEM.SYS - device driver is an extended memory manager that supervises the use of the computer's Extended memory so that no two application programs can use the same memory at[...]

Memory Device Drivers EMM.SYS The EMS memory manager provided with your TravelMate 3000, the EMM.SYS device driver, conforms to version 4.00 of the Lotus/Intel/Microsoft Expanded Memory Specification (EMS). EMM.SYS enables areas of system memory to be used as Expanded memory. Note: You cannot use EMM.SYS with Windows 3.0 in 386 standard or enhanced[...]

Memory Device Drivers Some application programs may require "backfill" memory, which is the unused area of standard memory that can be used by EMM.SYS as Expanded memory. For example, an application program may require only 256 KB or 512 KB of standard memory, leaving 384 KB and 128 KB of backfill. memory space, respectively, for use as E[...]

Memory Device Drivers If you do not specify any parameters, EMM.SYS uses the default values for each. Numeric values (nnnn) should be specified in decimal unless specifically noted otherwise in the following descriptions. Memory sizes should be specified in kilobytes (1024 bytes) without the last three digits at the end of the number; for example, [...]

Memory Device Drivers Contexts = nn (C=) specifies the number of contexts for windows 0 - 3 that can be saved by processes using EMS memory. The maximum number of contexts is 255; the minimum is 3. The default is the number of handles that are allocated. Depth = nn (D=) specifies the number of consecutive contexts that can be saved for a given hand[...]

Memory Device Drivers Include = xxxx-xxxx (L=) specifies a range of addresses that should always be used for EMS mapping. By default, the memory manager automatically excludes areas known to contain ROMs or video RAM. This parameter allows you to include a range of addresses that might be excluded by memory manager's automatic selection proces[...]

Memory Device Drivers Memory Manager Error Messages Error messages displayed by the memory manager are divided into two groups. The following first group displays general memory manager errors. Invalid parameter specified - One of the parameters specified on the command line in your CONFIG.SYS file is invalid. Expected equal after parameter - One o[...]

Memory Device Drivers Number of contexts must be at least 3 - The number of contexts specified is less than 3. The number of contexts specified must be between 3 and 255. See "Contexts" parameter earlier in this appendix. Number of contexts cannot exceed 255 - The number of contexts specified is greater than 255. The number of contexts sp[...]

Memory Device Drivers The following second group of error codes are specific to the TACT 83000 memory manager. Invalid hardware for memory manager - The memory manager was run on a system which did not contain the TACT 83000 chip set. No EMS memory allocated - No Expanded memory was specified using the Memory parameter, and no memory remained unall[...]

Memory Device Drivers if you need to specify special conditions for the use of the high-memory area, use the command in the following form: DEVICE=C:DOSHIMEM.SYS [/HMAMIN=h][/NUM- HANDLES=n] where: /HMAMIN=h h is the minimum amount of memory required by a TSR program or device driver to be loaded into HAM specify the amount of memory in kilobytes[...]

Memory Device Drivers RAMDRIVE.SYS A RAM disk is a portion of your computer's memory configured to simulate a disk drive. Such a disk, which may be called a virtual disk, can be accessed much faster than a normal disk drive. The data stored on a RAM disk disappears when computer power is turned off, so you must copy the contents of the RAM dis[...]

Memory Device Drivers SMARTDRV.SYS SMARTDRV.SYS is a disk-caching program used to reduce the time it takes your computer to read data from the hard disk. When SMARTDRV.SYS is installed, information from the hard disk is temporarily stored in a cache in Extended or Expanded memory. When needed, the data can be accessed by the processor directly from[...]
