This happens on IA-64 because there's - no BIOS. - * Makefile, README: Do not build biosdecode, ownership and - vpddecode on IA-64, as IA-64 systems have no BIOS. This was - quite tricky to keep both GNU make and BSD make happy, but it - seems that I finally succeeded. - -2007-02-13 Jean Delvare <khali@linux-fr.org> - - Update to support SMBIOS specification version 2.5, second round. - - * dmidecode.c: Decode new processor characteristics (multi-core, - multi-thread, 64-bit) (DMI type 4). - * dmidecode.c: Decode slot ID of AGP 8x and PCI Express slots (DMI - type 9). - - * dmidecode.c: Fix the mask of 3 bitfield tests.

It - was reported to be unreliable too many times, and was also - difficult to maintain. - -2006-05-10 Jean Delvare <khali@linux-fr.org> - - * dmidecode.c: Don't cast from u8* to dmi_header*, else - architectures which do not support unaligned memory accesses - may break. Instead, copy the members individually. That's a - bit slower, but that's also safer and we only need to do it - once per DMI entry, so it's not time critical. So far, we - were using a trick to later work around the unaligned memory - access, but the compiler would still warn about the risk, - which is always confusing. - * config.h, types.h, README: Automatically enable the unaligned - memory access workaround on ia64. - * types.h: Inline U64. It makes sense per se and also lets us - get rid of a warning about U64 being unused. - * dmidecode.c: Detect EFI at run-time rather than compilation- - time. Based on an original patch from Matthew Garrett. This - will make x86 binaries work for both PC systems with BIOS and - Macintosh systems with EFI. Also prevent a possible, though - unlikely, NULL-pointer dereference in the EFI code. - -2006-02-25 Jean Delvare <khali@linux-fr.org> - - * dmidecode.c: Fix typo reported by David Wilson (DMI case 3). - -2006-02-04 Jean Delvare <khali@linux-fr.org> - - * vpddecode.c: Update lookup table from revision 2006-01-31 of IBM - reference document (add product ID "7B"). - * version.h: Set version to 2.8. - -2006-01-21 Jean Delvare <khali@linux-fr.org> - - * vpddecode.c: The mysterious last character of xSeries records - may be a BIOS revision.

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 <khali@linux-fr.org> - - * vpddecode.c: Add product ID "NR". Reported by Klaus Muth. - * vpddecode.c: Update lookup table from revision 2005-10-06 of IBM - reference document (add product IDs "77" and "78"). - -2005-10-05 Jean Delvare <khali@linux-fr.org> - - Update to support IPMI specification version 2.0 (was 1.5). - - * dmidecode.c: Support IPMI interface type SSIF.

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 <khali@linux-fr.org> - - * dmiopt.c: Fix incorrect header include.
