在 grub4dos 的 readme_grub4dos.txt 文档中,你可以找到这方面的信息。John Cobb 的 hmload 命令,估计你可以用得上。你也可以到
http://sysdocs.stu.qmul.ac.uk/sysdocs/Comment/GrubForDOS/
去看看这方面的信息。
注意,直接用 dos 所建立的 ramdisk 是不行的。因为进入 grub4dos 后,DOS 就消失了,所以,dos 的RAMdisk设备也不能用了。
因此,你需要用 hmload 来把映像文件直接放在扩展内存,这样,进入 grub 后,是有办法访问扩展内存中的这个映像文件的。
这是比较高级的用法,你得准备自己使劲钻研、试验、探究,才会成功。
In the readme_grub4dos.txt document of grub4dos, you can find information on this. The hmload command by John Cobb might be useful for you. You can also go to
http://sysdocs.stu.qmul.ac.uk/sysdocs/Comment/GrubForDOS/
to see information on this.
Note that the RAMdisk established directly with DOS won't work. Because after entering grub4dos, DOS disappears, so the DOS RAMdisk device can't be used either.
Therefore, you need to use hmload to place the image file directly in extended memory, so that after entering grub, there is a way to access this image file in extended memory.
This is a more advanced usage. You need to be prepared to study, experiment, and explore by yourself to succeed.
