Windows NTConfig command line options 131
/DMACHECK
When calling NTConfig with the /DMACheck option,
NTConfig determines the amount of memory installed in the
Matrox 4Sight unit. In addition, it validates and corrects other
memory-related parameters. The standard NTConfig dialog
box is not displayed.
The memory-related parameters are considered valid when the
total amount of physical memory minus the total amount of
video memory reserved at boot time, minus the total amount of
DMA memory reserved by MIL, minus the total amount of
memory available to Windows NT Embedded equals 0. That is:
PhysicalMem - VideoMem – DMAMem – AvailMem = 0
If this equation is unbalanced, NTConfig will adjust the DMA
memory parameter accordingly. You will be advised that the
computer will reboot immediately so that the adjustments will
take effect. This command is useful for adjusting the amount
of memory available to the operating system if physical memory
(RAM) is added or removed while DMA memory is reserved by
MIL
/MEM
When calling NTConfig with the /Mem option, NTConfig
performs the same operations as /DMACHECK. However,
before validating and correcting memory-related parameters,
it reports these parameters.
/AUTOPOPUP
When calling NTConfig with the /Autopopup option,
NTConfig checks the registry to determine if the automatic
popup feature is enabled. If so, it displays the standard
NTConfig dialog box; otherwise it does nothing. This option is
used at bootup time to determine if the standard NTConfig
dialog box should be displayed. You can disable the automatic
popup feature using the checkbox in the standard NTConfig
dialog box.
