China DOS Union

The effect of GRUB for DOS is the same whether it is booted from the MBR or from the DOS command line. And the effect of booting from the MBR is better because the BIOS interrupt table and BIOS data area at this time have not been polluted by DOS.

In the case of the elder brother here, the difference occurs because the versions are different. grub_t07.exe is the latest version, while the one installed to the MBR is the old version.

Even if you use root (hd0,0) and setup (hd0) of grub_t07.exe to install, it is still the old version that is installed. Why? Because what is installed to the MBR is the (hd0,0)/boot/grub/stage2 file, which is completely separated from grub_t07.exe. At this time, it is okay to delete grub_t07.exe. Note that the stage2 file is old, and the stage2 file needs to be updated together after the official version is released.

－－－－－－－－

The stage2 file has been uploaded to your FTP space. You can give it a try. Replace the old stage2 file with it, and then use root (hd0,0) and setup (hd0) again to install to the MBR, and then the new version can be used.

For safety, here is another reminder, this is not an official release, and there may be serious bugs hidden in it. To ensure the safety of the machine, please try not to use the map command. This is a test version.

Hehe, thanks, it's a low-level mistake ^_^
I will add the readonly parameter and use it carefully
thx again

Your vfloppy can be slightly modified to load img files under win to replace the real A drive. Then, won't the usage be more extensive?

Just made it, let's try this again:

ftp://ftp.cosoft.org.cn/incoming/grub_t09.exe

Corrected several hidden bugs, should be relatively perfect.

Thanks

Good post

Learned something new!!
