Repacking T2502 with a modern deflate32 implementation adds 45 MB of usable payload space in the FreeDOS distribution media. These savings are nearly zero-cost and do not require retooling. Details here: https://docs.google.com/spreadsheets/d/1f_6OqBynrWtStkOux13g3XiuzTku75l5/view The FD14LIVE and FD14BNS images can be combined into one 74-minute compact disc master for bulk fabrication. Notes: * Using deflate64 instead of deflate32 adds 58 MB of payload space. This zip variant is compatible with unzip-6.00 in FreeDOS, but is incompatible with pkzip-2.04g. * The DOJS.ZIP and CURL.ZIP packages each contain a large SOURCES.7Z file that skews distribution size. In the next FreeDOS release, using 7z for all source code might obviate any more package removals. * Repacking everything as 7z adds 250 MB of usable payload space in the distribution media. A baseline 80386/4MB machine can unpack 7z archives having 1 MB dictionary sizes, which is slightly less than the sweet spot for the FreeDOS dataset. * On the FreeDOS dataset, 7zip-24.09 significantly outperforms rar-6.24, which is the last release that can create rar4 archives that are compatible with rar-2.90 for DOS. _______________________________________________ Freedos-devel mailing list Freedos-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freedos-devel
