[boot scriptor] Re: cdshell isolinux freeze/reboot?

The only way I've ever used CD Shell is to boot directly - I've never chained 
isolinux to CD Shell and then to isolinux.

As far as I know, based on my limited experience with CD Shell, using diskemu 
to run CD Shell would require diskemu be able to emulate a CD-ROM, but it 
doesn't do that - it does diskette images.  I could be totally wrong in that, 
but it looks to me like you're making this much more complicated than it has to 
be.

CD Shell is capable of processing lines and passing them to isolinux, so what 
it looks like you're trying to do by booting isolinux first could be 
accomplished by using loader.bin as the documentation I referenced indicates 
should be done and changing the cdshell.ini file to include the proper isolinux 
options and pass them to the isolinux command instead.

I may be mistaken, but I don't think you can use diskemu to start CD Shell, 
since diskemu emulates floppy disks, and CD Shell's execution explicity 
specifies that no emulation be used when burning the disc.

Perhaps I'm missing something in your goal here...

The cd initially boots to isolinux just fine, then I use diskemu to boot
cdshell.  Once inside cdshell I have problems using isolinux.  If, on
the cdshell command line provided with the ultimate boot cd, I try a
command like "isolinux gentoo" where gentoo is the name of a kernel
isolinux hangs.  More specifically the isolinux module that comes with
cdshell hangs.  Is there something related to the isolinux module that I
am missing or misconfiguring?

Thanks,
Jason
