From 53b310ce539cfadf1f2fad5927a9e8f88ec9db13 Mon Sep 17 00:00:00 2001 From: "Collin L. Walling" Date: Fri, 23 Feb 2018 10:43:18 -0500 Subject: s390-ccw: use zipl values when no boot menu options are present If no boot menu options are present, then flag the boot menu to use the zipl options that were set in the zipl configuration file (and stored on disk by zipl). These options are found at some offset prior to the start of the zipl boot menu banner. The zipl timeout value is limited to a 16-bit unsigned integer and stored as seconds, so we take care to convert it to milliseconds in order to conform to the rest of the boot menu functionality. This is limited to CCW devices. For reference, the zipl configuration file uses the following fields in the menu section: prompt=1 enable the boot menu timeout=X set the timeout to X seconds To explicitly disregard any boot menu options, then menu=off or must be specified.
