lpctool To access devices on the LPC bus, use the lpctool. The lpctool allows access on the LPC bus by using I/O transactions at the processor level. This access does not include LPC interfaces in other devices. Other DIAG-OS tools use lpctool to read LPC-connected registers. CLI options DellEmc Diag - LPC Tool version 1.0, x.xx.x.x-x build, 2017/05/23, Syntax: lpctool Show the help-text:= lpctool --h (or) lpctool -h Read the specified address:= lpctool --read --addr= --count= [--size=] (or) lpctool -r -a -C [-z ] Write data at the specified address:= lpctool --write --addr=address --val=data [--size=b,w or l] (or) lpctool -w -a -V [-z ] Execute repeatedly command by count:= lpctool --iteration=max/ [option1] [option2]...

The memtool performs address bus and data tests that moves 1s or 0s through the bus lines to detect stuck, missing, bridged, or other issues found during board tests. The tool also places hamming values or addresses into memory to test and report failing bits. All tests are similar to the memtest86 application but are available through the CLI.
