Syslinux - May 2003 - Disk error 01: AX=4200, drive 82

Hi, 

I get the error message 

	isolinux: Disk error 01: AX=4200, drive 82

booting the new College Linux CD on my Dell GX100.   

What does this message mean, and what is the recommended workaround?  

Please cc me on any replies; I'm not subscribed to this list.

Thank you for your help.

I have located the problem.  It is related to the attempted inclusion of 
a picture by boot.msg - it turns out that picture was length zero and 
its attempted inclusion messed up everything.

Now, the reason why the picture length was 0 is again the same old perl 
UTF-8 problems in RedHat 9.  The ppmtolss16 tool is perl and when ran 
with LANG=en_US.UTF-8 this is what will output:
/usr/bin/ppmtolss16: Premature EOF at (319,212) of (640,256)
and the output is empty. After switching LANG to en_US it will be just fine.

Perhaps ppmtolss16 should "use bytes;" ?

It does (in 2.04):

eval { use bytes; };

... the eval { } is to prevent it from tossing cookies on older Perl 
versions.
