This parameter controls a software lock that causes
the four-channel DMA controller to use only one channel at a time,
that is, not to use its capability to perform
transfers on separate channels simultaneously.
This is a software solution for problems with early production runs of
the chips.
Setting the value to ``1''
prevents simultaneous use of the channels within a single chip.
Setting the value to ``2''
prevents simultaneous use of all channels for all chips.
NCPYRIGHT
The size of a kernel data structure used to print
console initialization messages.
NUMREGPT
Specifies the number of regular pseudo-terminals.
Changing this tunable parameter is not sufficient to change the number
of pseudo-terminal devices on your system;
you must also reinstall the nsu package.
NUMSCOPT
Specifies the number of SCO OpenServer-compatible pseudo-terminals.
Changing this tunable parameter is not sufficient to change the number
of pseudo-terminal devices on your system;
you must also reinstall the acp package.
PDI_TIMEOUT
Enables and disables the SCSI command timeouts that allow
for recovery from bus and device hangs.
The default value is ``1'',
which indicates that SCSI command timeouts are enabled.
When the value is set to ``0'', the SCSI command timeouts are disabled.
SDI_REGISTER_DELAY
Specifies the delay period, in seconds, for devices becoming ready.
