From 18b02360b9dba6ca61538923e27b5ba68a2b3299 Mon Sep 17 00:00:00 2001 From: Ruud Schramp Date: Mon, 11 Apr 2011 07:46:27 +0000 Subject: [PATCH] Add detection/dump support for ServerEngines SE-SM 4210-P01. Note that the registers and their defaults are mostly based on educated guessing, due to the lack of datasheet.
