Hello Michael, I use the below and generate iso image successfully. I check with WinImage and all Chinese name file, long folder name reserved. However, when I use nero 6.3.0.3 to burn the iso image, it still give me 80200279 mkisofs -iso-level 4 -joliet-long -V "Emergency" -appid "MKISOFS" -publisher "LAM Chi-fung" -sysid "Win32" -verbose -nobak -eltorito-boot bscript/loader.bin -no-emul-boot -boot-load-size 4 -hide bscript/loader.bin -hide boot.catalog -o f:\bsc_mkisofs.iso "G:\Emergency" I try another experiment, obey all iso restriction to create the bootable CD in Nero http://www.pacific.net.hk/~cflam/config4.jpg http://www.pacific.net.hk/~cflam/config5.jpg and the CD boot without problem!!! Seems that bootscript/CD Shell don't like the iso-level-4/Joliet (over 63 characters) features. Still don't know how to work out. ;( Regds LAM Chi-fung ============================================================ Boot Scriptor mailing list -- http://www.bootscriptor.org Change your subscription options at: //www.freelists.org/list/bscript
