decode-dimms is a small utility that displays the contents of DIMM memory
|
||||
SPD ROMs in human-readable form.
|
||||
|
||||
This version of decode-dimms can even directly read the SPD ROM data from
|
||||
the sysctl variables created by the spdmem device driver (NetBSD-only).
|
||||
The decode-dimms utility provides a human-readable display of the contents
|
||||
of the SPD ROMs on memory DIMMs. On NetBSD, it can use spdmem(4) as the
|
||||
source of the ROM data. Output formats include a side-by-side HTML table
|
||||
for multiple DIMMs so you can easily compare them.
