<QUOTE>
We just bought a Dell Inspiron 7000 Laptop and cannot get emm386.exe to load unless we set it to: emm386.exe /frame=none auto.  When we set it like that AREV won't load.  Dell wasn't much help and said to send the laptop back.  Any suggestions?

<QUOTE>Don't know if this helps, but here's some detailed command line options for EMM386.EXE and HIMEM.SYS.  Remember, if you load EMM386.EXE in your CONFIG.SYS, you must load HIMEM.SYS as well.



You also might want to try adding DOS=HIGH,UMB as well.

EMM386.EXE

==========



Provides access to the upper memory area and uses extended memory to

simulate expanded memory. This device driver must be loaded by a DEVICE

command in your CONFIG.SYS file and can be used only on computers with an

80386 or higher processor.



EMM386 uses extended memory to simulate expanded memory for programs that

can use expanded memory. EMM386 also makes it possible to load programs and

device drivers into upper memory blocks (UMBs).



Syntax



    DEVICE=drive:pathEMM386.EXE ON|OFF|AUTO memory MIN=size

    W=ON|W=OFF Mx|FRAME=address|/Pmmmm Pn=address X=mmmm-nnnn

    I=mmmm-nnnn B=address L=minXMS A=altregs H=handles D=nnn

    RAM=mmmm-nnnn NOEMS NOVCPI HIGHSCAN VERBOSE WIN=mmmm-nnnn

    NOHI ROM=mmmm-nnnn NOMOVEXBDA ALTBOOT NOBACKFILL



Parameters



drive:path

    Specifies the location of the EMM386.EXE file.



ON|OFF|AUTO

    Activates the EMM386 device driver (if set to ON), or suspends the

    EMM386 device driver (if set to OFF), or places the EMM386 device driver

    in auto mode (if set to AUTO). Auto mode enables expanded-memory support

    and upper memory block support only when a program calls for it. The

    default value is ON. Use the EMM386 command to change this value after

    EMM386 has started.



memory

    Specifies the maximum amount of extended memory (in kilobytes) that you

    want EMM386 to provide as expanded/Virtual Control Program Interface

    (EMS/VCPI) memory. This amount is in addition to the memory used for

    UMBs and EMM386 itself. Values for memory are in the range 64 through

    the lesser of either 32768 or the amount of extended memory available

    when EMM386 is loaded. The default value is the amount of free extended

    memory. If you specify the NOEMS switch, the default value is 0. EMM386

    rounds the value down to the nearest multiple of 16.



Switches



MIN=size

    Specifies the minimum amount of EMS/VCPI memory (in kilobytes) that

    EMM386 will provide, if that amount of memory is available. EMM386

    reserves this amount of extended memory for use as EMS/VCPI memory when

    EMM386 is loaded by the DEVICE=EMM386.EXE command in your CONFIG.SYS

    file. EMM386 may be able to provide additional EMS/VCPI memory (up to

    the amount specified by the MEMORY parameter) if sufficient XMS memory

    is available when a program requests EMS/VCPI memory. Values are in the

    range 0 through the value specified by the MEMORY parameter. The default

    value is 256. If you specify the NOEMS switch, the default value is 0.

    If the value of MIN is greater than the value of MEMORY, EMM386 uses the

    value specified by MIN.



W=ON|W=OFF

    Enables or disables support for the Weitek co-processor. The default

    setting is W=OFF.



Mx

    Specifies the address of the page frame. Valid values for x are in the

    range 1 through 14. The following list shows each value and its

    associated base address in hexadecimal format:



            1 =] C000h     8 =] DC00h

            2 =] C400h     9 =] E000h

            3 =] C800h    10 =] 8000h

            4 =] CC00h    11 =] 8400h

            5 =] D000h    12 =] 8800h

            6 =] D400h    13 =] 8C00h

            7 =] D800h    14 =] 9000h



    Values in the range 10 through 14 should be used only on computers that

    have 512K of memory.



FRAME=address

    Specifies the page-frame segment base directly. To specify a specific

    segment-base address for the page frame, use the FRAME switch, and

    specify the address you want. Valid values for address are in the ranges

    8000h through 9000h and C000h through E000h, in increments of 400h. To

    provide expanded memory and disable the page frame, you can specify

    FRAME=NONE; however, this may cause some programs that require expanded

    memory to work improperly.



/Pmmmm

    Specifies the address of the page frame. Valid values for mmmm are in

    the ranges 8000h through 9000h and C000h through E000h, in increments of

    400h.



Pn=address

    Specifies the segment address of a specific page, where n is the number

    of the page you are specifying and address is the segment address you

    want. Valid values for n are in the range 0 through 255. Valid values

    for address are in the ranges 8000h through 9C00h and C000h through

    EC00h, in increments of 400h. The addresses for pages 0 through 3 must

    be contiguous in order to maintain compatibility with version 3.2 of the

    Lotus/Intel/Microsoft Expanded Memory Specification (LIM EMS). If you

    use the Mx switch, the FRAME switch, or the /Pmmmm switch, you cannot

    specify the addresses for pages 0 through 3 for the /Pmmmm switch.



X=mmmm-nnnn

    Prevents EMM386 from using a particular range of segment addresses for

    an EMS page or for UMBs. Valid values for mmmm and nnnn are in the range

    A000h through FFFFh and are rounded down to the nearest 4-kilobyte

    boundary. The X switch takes precedence over the I switch if the two

    ranges overlap.



I=mmmm-nnnn

    Specifies a range of segment addresses to be used (included) for an EMS

    page or for UMBs. Valid values for mmmm and nnnn are in the range A000h

    through FFFFh and are rounded down to the nearest 4-kilobyte boundary.

    The X switch takes precedence over the I switch if the two ranges

    overlap.



B=address

    Specifies the lowest segment address available for EMS "banking"

    (swapping of 16KB pages). Valid values are in the range 1000h

    through 4000h. The default value is 4000h.



l=minXMS

    Ensures that the specified amount (in kilobytes) of extended memory will

    still be available after EMM386 is loaded. The default value is 0.



A=altregs

    Specifies how many fast alternate register sets (used for multitasking)

    you want to allocate to EMM386. Valid values are in the range 0 through

    254. The default value is 7. Every alternate register set adds about 200

    bytes to the size in memory of EMM386.



H=handles

    Specifies how many handles EMM386 can use. Valid values are in the range

    2 through 255. The default value is 64.



D=nnn

    Specifies how many kilobytes of memory should be reserved for buffered

    direct memory access (DMA). Discounting floppy disk DMA, this value

    should reflect the largest DMA transfer that will occur while EMM386 is

    active. Valid values for nnn are in the range 16 through 256. The

    default value is 32.



RAM=mmmm-nnnn

    Specifies a range of segment addresses to be used for UMBs and also

    enables EMS support. If you do not specify a range, EMM386 uses all

    available adapter space to create UMBs and a page frame for EMS.



NOEMS

    Provides access to the upper memory area but prevents access to expanded

    memory.



NOVCPI

    Disables support for VCPI programs. This switch must be used with

    the NOEMS switch. If you specify the NOVCPI switch without specifying

    the NOEMS switch, EMM386 does not disable VCPI support. If you specify

    both switches, EMM386 disregards the MEMORY parameter and the MIN

    switch. Disabling support for VCPI programs reduces the amount of

    extended memory allocated.



HIGHSCAN

    Specifies that EMM386 use an additional check to determine the

    availablity of upper memory for use as UMBs or EMS windows. On some

    computers, specifying this switch may have no effect or cause EMM386 to

    identify upper memory areas as available when they are not. As a

    result, your computer might stop responding.



VERBOSE

    Directs EMM386 to display status and error messages while loading. By

    default, EMM386 displays messages only if it encounters an error

    condition. You can abbreviate VERBOSE as V. (To display status messages

    without adding the VERBOSE switch, press and hold down the ALT key 

    while EMM386 starts and loads.)



WIN=mmmm-nnnn

    Reserves a specified range of segment addresses for Windows instead of

    for EMM386. Valid values for mmmm and nnnn are in the range A000h

    through FFFFh and are rounded down to the nearest 4-kilobyte boundary.

    The X switch takes precedence over the WIN switch if the two ranges

    overlap. The WIN switch takes precedence over the RAM, ROM, and I

    switches if their ranges overlap.



NOHI

    Prevents EMM386 from loading into the upper memory area. Normally, a

    portion of EMM386 is loaded into upper memory. Specifying this switch

    decreases available conventional memory and increases the upper memory

    area available for UMBs.



ROM=mmmm-nnnn

    Specifies a range of segment addresses that EMM386 uses for shadow

    RAM--random-access memory used for read-only memory (ROM). Valid values

    for mmmm and nnnn are in the range A000h through FFFFh and are rounded

    down to the nearest 4-kilobyte boundary. Specifying this switch may

    speed up your system if it does not already have shadow RAM.



NOMOVEXBDA

    Prevents EMM386 from moving the extended BIOS data from conventional

    memory to upper memory.



ALTBOOT

    Specifies that EMM386 use an alternate handler to restart your computer

    when you press CTRL+ALT+DEL. Use this switch only if your computer stops

    responding or exhibits other unusual behavior when EMM386 is loaded and

    you press CTRL+ALT+DEL.



NOBACKFILL

    When EMM386 is configured to provide upper memory blocks (by using the

    NOEMS or RAM switches), EMM386 will also automatically backfill

    conventional memory if there is less than 640k, in order to bring total

    conventional memory up to 640k.  However, because Windows does not

    support backfilled conventional memory, use the NOBACKFILL switch if

    your computer has less than 640K of conventional memory.





HIMEM.SYS

=========



HIMEM is an extended-memory manager--a program that coordinates the use of

your computer's extended memory, including the high memory area (HMA), so

that no two programs or device drivers use the same memory at the same

time.



You install HIMEM by adding a DEVICE command for HIMEM.SYS to your

CONFIG.SYS file. The HIMEM.SYS command line must come before any commands

that start programs or device drivers that use extended memory; for

example, the HIMEM.SYS command line must come before the EMM386.EXE command

line.



Syntax



    DEVICE=drive:pathHIMEM.SYS /A20CONTROL:ON|OFF /CPUCLOCK:ON|OFF

    /EISA /HMAMIN=m /INT15=xxxx /MACHINE:xxxx /NOABOVE16 /NOEISA

    /NUMHANDLES=n /SHADOWRAM:ON|OFF /TESTMEM:ON|OFF /VERBOSE /X



In most cases, you won't need to specify command-line options. The default

values for HIMEM.SYS are designed to work with most hardware.



Parameter



drive:path

    Specifies the location of the HIMEM.SYS file. HIMEM.SYS should always be

    located on the same drive that contains your MS-DOS files. If the

    HIMEM.SYS file is in the root directory of your startup drive, you don't

    need to include a path. However, you must always include the complete

    filename (HIMEM.SYS).



Switches



/A20CONTROL:ON|OFF

    Specifies whether HIMEM is to take control of the A20 line even if A20

    was on when HIMEM was loaded. The A20 handler gives your computer access

    to the HMA. If you specify /A20CONTROL:OFF, HIMEM takes control of the

    A20 line only if A20 was off when HIMEM was loaded. The default setting

    is /A20CONTROL:ON.



/CPUCLOCK:ON|OFF

    Specifies whether HIMEM is to affect the clock speed of your computer.

    If your computer's clock speed changes when you install HIMEM,

    specifying /CPUCLOCK:ON may correct the problem; however, enabling this

    option slows down HIMEM. The default setting is /CPUCLOCK:OFF.



/EISA

    Specifies that HIMEM should allocate all available extended memory. This

    switch is necessary only on an EISA (Extended Industry Standard

    Architecture) computer with more than 16 MB of memory; on other

    computers, HIMEM automatically allocates all available extended memory.



/HMAMIN=m

    Specifies how many kilobytes of memory a program must require for

    HIMEM to give that program use of the HMA. Only one program can

    use the HMA at a time; HIMEM allocates the HMA to the first program

    that meets the memory-use requirements set by this option. You can

    specify a value from 0 to 63.



    Set /HMAMIN to the amount of memory required by the program that

    uses the most HMA memory.



    The /HMAMIN option is not required; the default value is zero. Omitting

    this option (or setting it to zero) specifies that HIMEM allocate the

    HMA to the first program that requests it, regardless of how much of

    the HMA the program is going to use.



    The /HMAMIN option has no effect when Windows is running in 386 Enhanced

    mode.





/INT15=xxxx

    Allocates the amount of extended memory (in kilobytes) to be reserved

    for the Interrupt 15h interface. Some older programs use the

    Interrupt 15h interface to allocate extended memory rather than using

    the XMS (eXtended-Memory Specification) method provided by HIMEM. If you

    use these programs, you can ensure enough memory is available to

    them by setting xxxx to 64 KB larger than the amount required by the

    program.



    You can specify a value from 64 to 65535; however, you cannot specify

    more memory than your system has available. If you specify a value less

    than 64, the value becomes 0. The default value is 0.



/MACHINE:xxxx

    Specifies what type of computer you are using. Usually, HIMEM can detect

    your computer type successfully; however, there are a few computers that

    HIMEM cannot detect. On such systems, HIMEM uses the default system type

    (IBM AT or compatible). You might need to include the /MACHINE option if

    your computer is a type that HIMEM cannot detect and if HIMEM does not

    work properly on your system by using the default system type.



    Currently, systems that require this option include Acer 1100, Wyse, and

    IBM 7552.



    The value for xxxx can be any of the codes or their equivalent numbers

    listed in the following table.

bullmicral   16      Bull Micral 60



dell         17      Dell XBIOS





/NOABOVE16

    Specifies not to use INT 15h (ax==E801h) Compaq Bigmem support to scan 

    for extended memory.



/NOEISA

    Specifies that HIMEM should not do EISA scanning for extended memory.



/NUMHANDLES=n

    Specifies the maximum number of extended-memory block (EMB) handles that

    can be used simultaneously. You can specify a value from 1 to 128; the

    default value is 32. Each additional handle requires an additional 6

    bytes of memory.



    The /NUMHANDLES option has no effect when Windows is running in 386 

    Enhanced mode.



/SHADOWRAM:ON|OFF

    Specifies whether to disable shadow RAM (SHADOWRAM:OFF) or to leave the

    ROM code running from RAM (SHADOWRAM:ON).



    Some computers make ROM code run faster by "shadowing" it in RAM--that

    is, by copying the ROM code into faster RAM memory at startup, which

    uses some extended memory. On computers that use shadow RAM and have

    less than 2 MB of RAM, HIMEM usually attempts to disable shadow RAM to

    recover additional extended memory for Windows to use. (HIMEM can

    disable shadow RAM only on certain types of systems.) When HIMEM

    disables shadow RAM, the ROM code runs in the slower ROM instead of RAM;

    therefore, your computer might run slightly slower than it did before.



/TESTMEM:ON|OFF

    Determines whether HIMEM performs a memory test when your computer

    starts. By default, HIMEM tests the reliability of your computer's

    extended memory each time your computer starts. This test can identify

    memory that is no longer reliable; unreliable memory can cause system

    instability or loss of data. HIMEM's memory test is more thorough than

    the standard power-up memory test performed by most computers. To

    prevent HIMEM from performing the memory test, specify /TESTMEM:OFF.

    Disabling the memory test will shorten the startup process. (The default

    setting is /TESTMEM:ON.)



/VERBOSE

    Directs HIMEM to display status and error messages while loading. By

    default, HIMEM does not display any messages unless it encounters an

    error. You can abbreviate /VERBOSE as /V. (To display status messages

    without adding the /VERBOSE switch, press and hold the ALT key while

    HIMEM starts and loads.)



/X

    Specifies not to use INT 15h (ax==E820h), the latest extended memory 

    support API.
