Overrides the compile-time set value of TCBHASHSIZE or
|
||||
the preset default of 512. Must be a power of 2.

|

set hw.physmem=<value> MAXMEM (i386 only)
|

|
||||
Limits the amount of physical memory space available to
|
||||
the system to <value> bytes. <value> may have a k, M or G
|
||||
suffix to indicate kilobytes, megabytes and gigabytes
|
||||
respectively. Note that the current i386 architecture
|
||||
limits this value to 4GB.
|
||||
|
||||
On systems where memory cannot be accurately probed,
|
||||
this option provides a hint as to the actual size of
|
||||
system memory (which will be tested before use).
