Alice overwrites already existing partition-descriptions (SLES7) / reboot after kerner-installing (smp)

Hello, 

1.)
  i've a question about distributing partitions with linux.
  I've an already existing partioning on an compaq-server and i would like to keep it 
  in the system!
  Does anybody know a possibility to keep this partition without overwriting of alice 
  thru automatic-partitioning?

2.)
  i installed a "snmp-kernel" and the system would like to reboot now.
  That's OK for me but i don't want to acknowledge this rebooting?
  I didn't find a flag to switch an automatic-acknowledgeing on.
  Do you know a chance to do that?

Kind regards, 

Heiko Menzel
