用DOS的FDISK划分出的扩展分区(Extend DOS)不具有像主DOS分区(Pri DOS)那样引导系统的能力,这是众所周知的事情。不过,这并不是无法改变的。笔者对硬盘分区表作了一番比较分析后,仅改动一个字节,便将扩展分区改造成了主DOS分区,从而在同一硬盘中建立了两个C:盘。在第一个C:盘中安装MS-DOS6.22和中文Win 95,在另一个C:盘中安装Win 98(测试版),每一种操作系统都可以独 It is a well-known fact that Extend DOS, which is partitioned by DOS’s FDISK, does not have the ability to boot a system as a primary DOS partition (Pri DOS). However, this is not impossible to change. After the author of the hard disk partition table made some comparative analysis, only a change of bytes, they will be transformed into a primary partition DOS partition, which in the same hard disk to establish two C: disk. Install MS-DOS 6.22 and Chinese Win 95 in the first C: drive and Win 98 (beta) in another C: drive for each operating system
