当三星2006年推出它的第一部UMPC（就是后来的上网本）时，它尝试了双重启动环境。

When Samsung came out with one of the first UMPCs (later to be known as Net Books) back in 2006, it tried a dual boot environment.

提示：如果您想双重启动需要柱面对齐的 Linux 和一个旧版操作系统，尝试在成倍的 8 个柱面上调整所有分区的开头。

Tip: If you want to dual-boot between Linux and an older operating system that requires cylinder alignment, try aligning the starts of all your partitions on multiples of eight cylinders.

对于必须使用较早版本的 JVM 的系统，可以通过设置属性 derby.database.forceDatabaseLock=true 来减少双重启动。

With systems where an earlier JVM must be used, dual-booting can be minimized by setting the property derby.database.forceDatabaseLock=true .
