My knowledge is based on the Linux version. Both version should create compatible arcgives. Look at the manual: There are several options to increase compression ratio. For me -mx=9 (1GB RAM needed) works fine. 7z for windows should have equal/identical/similiar setting available. The compression ration of (p)7zip using LZMA compression is far better than that of gzip -- and it costs more time to compress... ... > # mount /mnt/cdrom > # zcat /mnt/cdrom/win98.gz | dd of=/dev/(win98) 7z x -so win98.7z | dd of=/dev/(win98) > If even gzip -9 can't get the partition small enough for you, I'm not > sure what to do. ...then try 7z/p7zip. Ony my two cent -- your mileage may vary... Keep hacking! mcc PS: p/7zip is GPL'ed.
