格式化后磁盘只有1.38M,redhat的引导盘制作不了，怎么办？

可能解：

En_route

1.38M = 1.38 x 1,024 x 1024 = 1,447,035 bytes

Should be adequate for most Linux distributions unless you compile your own, somewhat fattened kernel.

小猴子的爸爸

用rawrite也不行的，关键是一个软盘就是1。38M(根据En_route的帖子)，而boot.img有1。4M(redhat 8.0的就是这么大的说)，不知道怎么给写进去的。

你在纯 Dos底下用rawrite应该可以的
我就是这样的
它自己会自动的算出磁道的，然后写进去
那个1.38MB是在Windows底下看到的磁盘大小，没有关系的，其实还是1.44MB，只不过Windows不算引导区与FAT表以后的大小

En_route

Further arithmetic

1.44M = 1,000 x 1,024 = 1,474,560 bytes

AND what about \dosutils\rawritewin -- rawrite under windows? that comes with RedHAT 8.0 ? Worth a try and

GOOD LUCK

建立linux文件系统，#mke2fs /dev/fd0
再用做引导盘的命令：mkbootdisk --/dev/fd0 <内核版本>;
如redhat8.0:mkbootdisk --/dev/fdo 2.4.18-14
