ORA-01534 rollback segment 'R1' does not exist

Greetings
HELP!! We are using oracle 8.0.5 ...
The database will not open because it says the system
rollback segment does not exist.
The database mounts but won't open. from the file system checks,
the dbf file that contains the system rollback segment appears to
be fine.
Is there anyway to recreate the sys rb seg ? any way to correct
whatever is causing it to think it doesn't exist?
or if it is just hosed, is there any way to retrieve the data in
the data dbf files through another oracle installation or another
oracle database??
Thanks for any input!

Check your init<SID>.ora file. Check the parameter
rollback_segments. If its value contains R01, delete R01. After
that, save the file and startup again.
