This is needed for some eServer xSeries - 206. Still emit a warning if a VPD record is found not on a - 16-byte boundary. - -2005-10-26 Jean Delvare - - * vpddecode.c: Add product ID "NR".

Do not display the default flash - image file name anymore, it's not so useful and the field length - is now uncertain. - * vpdopt.c, vpdopt.h: New. - * Makefile, vpddecode.c, vpdopt.c, vpdopt.h: Move the command line - handling of vpddecode to a separate source file. - * vpddecode.c, vpdopt.c, vpdopt.h: Add option -s, --string. It - prints one selected VPD string instead of the regular output. - -2005-09-24 Jean Delvare - - * dmiopt.c: Fix incorrect header include. The strcasecmp function - is defined in <strings.h>, not <string.h>. Reported by Petter - Reinholdtsen. - -2005-09-14 Jean Delvare - - * dmidecode.h: New. - * dmidecode.c, dmidecode.h, Makefile: Export four specific - decoding functions, make them suitable for external call. - * dmidecode.c, dmiopt.c, dmiopt.h, Makefile: Make it possible - for --string to print decoded binary data rather than only - DMI strings.
