- The following command line switches may be used for configuring
- GCD for unique hardware and software situations. To configure
- GCD type the following:
- CFIG386 GCD -switches
- where the switches are detailed below. Computervision can not
- qualify GCD on all hardware platforms, these switches are
- intended only to attempt to alleviate the known hardware
- inconsistencies.
-
- -CLEAR
- Clears previously set CFIG386 switches.
-
- -MINREAL, MAXREAL nparagraphs
- Controls how much conventional memory (memory below 640k) is left
- free for GCD to use. GCD defaults are -MINR 00100h &
- -MAXR 0ffffh
-
- -MINIBUF, MAXIBUF nkilobytes
- Controls how much memory is allocated to the data buffer used for
- DOS and BIOS function calls. GCD defaults are:
- -MINI 1
- -MAXI 4
-
- -EXTLOW, EXTHIGH address
- Limits the amount of extended memory (memory above 1 megabyte)
- that GCD may use. GCD defaults are:
- -EXTL 100000h (1 megabyte)
- -EXTH FFFFFFFFh (4 gigabytes)
-
- -INTMAP vector
- Disables remapping of interrupt vectors to allow protected mode
- memory resident (TSR) programs to be installed. GCD default is:
- -INTM 8
-
- -PRIMAP vector
- Disables remapping of the BIOS print screen function call. GCD
- default is allow remapping.
-
- -NOPAGE
- Prevents GCD from using the 80386's hardware paging functionality
- to perform memory management. Use this switch for early versions
- of the 80386 chip (B1 and earlier). GCD default is to use
- paging.
-
- -NOBIM
- Used to disable the automatic use of Compaq built-in memory
- (mapped above 14 megabytes). GCD default is not disabled.
-
- -VDISK
- Handles compatibility problems with programs that do not
- correctly follow the VDISK standard for allocating extended
- memory. GCD default is not used.
-
- -B0
- Allows GCD to run on a rev B0 80386 chip. GCD default is not
- used.
-
- -CEMM
- Turns off the Compaq CEMM or compatible EMS emulator to switch
- the 80386 into real mode for running GCD. GCD default is not
- used.
-
- -XT
- Informs GCD that it is executing on a IBM PC or PC/XT compatible
- with a 386 board such as the Intel Inboard/PC. This is automatic
- on rev B1 and later 30386 chips. GCD default is not used.
-
- -MAXVCPI nbytes
- Controls how much Virtual Control Program Interface (VCPI) memory
- is available to GCD. Please see the Using Display Lists section
- of the GCD documentation for more information. GCD default is
- -MAXV 2750000
-
- -SWAPDIR D:
- Selects the hard drive to write the virtual memory file, if
- created. The virtual memory file is created if there is not
- enough available memory to load GCD entirely into memory. GCD
- default is to write to the root directory of the current drive.
