Hi, I have added InnoDB tables to current MySQL binaries: if you want to give it a test, please get http://os2power.dnsalias.com/yuri/mysql2/innodb-3-23-50-a2.zip This is only the mysqld binary, must be installed over an existing installation. This binary includes also a small fix for proper buffer flushing. Since InnoDB is a backend on top of MySQL, more resources are used at startup: 7 additional threads are started, and more disk space is required. If you want to skip InnoDB support, please add skip-innodb to the [mysqld] section of my.cnf, or --skip-innodb to mysqld command line. To enable InnoDB, at least this command must placed in my.cnf: innodb_data_file_path = ibdata1:10M:autoextend Please refer to MySQL online documentation for questions about installing and using innodb tables; please post here for bugs ;-) Yuri Dario
