From f8970f53eff5114f819df84196efa4e4539cbba1 Mon Sep 17 00:00:00 2001 From: Alexander Couzens Date: Sat, 10 Oct 2015 16:04:59 +0200 Subject: mainboard/lenovo: reserve century byte The century byte is used by most RTC (default 0x32@nvram). Even the century byte can disabled via ACPI it's more safe to reserve it's space. Because some RTC will act with that byte anyhow. Some OS overwrite it when syncronize the RTC.
