Unable to start the MySQL start service step

MySQL used by myself uses the MyISAM database and does not involve InnoDB. Therefore, we plan not to load the InnoDB Engine directly.
Add skip-InnoDB to my. ini (/etc/My. CnF in Linux.
After I set it like this, there is no problem in Linux. I started MySql in WINXP on my local machine today, prompting that the MySQL cannot be started. Check the error log of the MySQL directory:
Reference
090613 10:15:27 [Error] default storage engine (InnoDB) is not available
090613 10:15:27 [Error] aborting

090613 10:15:27 [note] C:/www/MySQL/bin/mysqld-NT: shutdown complete

It is estimated that after the parameter is added last time, it never starts up... MySQL of the local machine has not been used for a long time.
Check, my. in INI, the default-storage-engine = InnoDB engine is set to InnoDB, and skip-InnoDB is added to it.

Change default-storage-engine to MyISAM, and MySQL starts OK!
You can delete the ibdata1, ib_logfile0, and ib_logfile1 files in the data directory under skip-InnoDB.

After the test, when Skip-InnoDB is not added, the three files are deleted and the three files are automatically created at startup. The log is as follows:
Reference
InnoDB: The first specified data file./ibdata1 did not exist:
InnoDB: a new database to be created!

Delete these three files, add skip-InnoDB, and then start the log:
