mkisofs questions.

[Thomas D. Ward]

Hi, list. I'm having some problems with mkisofs, and I was hoping someone 
could answer them for me.
I've got a friend who is on dialup like me, but wants to try Linux. I'm 
attempting to make Red Hat 9.0 iso images from my disks  with mkisofs 
and am 
ending up with 
many iso images that don't work properly like the ones you download do. 
For example my image for the disk 1 won't boot leaving me to believe I am 
not correctly creating the portion of the iso dealing with bootible 
options.
Another problem all the files and  directories with  capitals in them are 
coming out lowercase really making me scratch my head.
Can anyone shed some light on what I am doing wrong and what I need to 
pass to mkisofs to make a properly working iso image of the Linux cd set? 
Many thanks.
