Re[2]: [debian-knoppix] Burning knoppix ISO image problem

[Stephen Liu <satimis@writeme.com>]

Hi Kilian,

Thanks for your advice.

I can't use KOnCD or Xcdroast because I download knoppix ISO image in a 
WinXP box.  RH8.0 is also in the same PC (using mobile rack to change the 
harddisc) .  I can only use Easy CD-Creator 5 in WinXP.

I have tried dao at 4X speed but also failed.  I am going to copy knoppix 
ISO image to a CDRW and then copy the knoppix ISO image from CDRW to a 
folder in RH8.0.  Start to burn knoppix ISO image on Linux environment 
using KOnCD.

Any precaution I have to take?  Can I save knoppix ISO image to /tmp ?

Thanks

Stephen
