Sorry? Currently supported DOS versions are: MS-DOS 3.30 and larer; FreeDOS kernel build 2032 and larer.



Programs such as TSRs and device drivers may also change the VIOS interrupt vector table. Make sure those programs are not running, then try again

When I use FreeDOS, a problem occurs. When running GRUB in FreeDOS, the following prompt appears:

Using 1.0final and beta9src9 doesn't work. It's the combination of command.exe + kernel.sys.

But GRUB4DOS can be run with MS-DOS. Is this incompatible?

Please further explain whether the command is from Microsoft or comes with FreeDOS.

Freedos comes with it

Both of these have been tried, neither works

Thanks for the report. Just wait for the update. You can follow the changes on http://grub4dos.jot.com/.

There is also a problem that grub4dos 0.4.2pre9 cannot execute grub-install and will report an error. grub4dos 0.4.2pre8 can execute grub-install. grub.exe grldr. Continue to support no.

Thanks to store88 for the continuous attention and help.

The problem with grub-install was resolved yesterday and has been uploaded to http://grub4dos.jot.com/.

I checked the issue with FreeDOS, and it's not really a problem. I downloaded fdboot.img. When it boots up, there's a menu. You select

2. FreeDOS Safe Mode (don't load any drivers)

Then you can execute grub.exe after entering DOS.

Why is it that I still can't do it, and the original error still occurs

Currently, GRUB4DOS only supports a simple environment with FreeDOS's kernel.sys plus a command.com. Loading any other device drivers or complex environments of TSR may cause failure. Even Himem and emm386 are not supported.

You might as well make a FreeDOS boot disk by yourself, which only contains these two files (and copy a grub.exe into it) and see if it works?

I first load the img of the FreeDOS kernel from GRUB4DOS, and then when running GRUB, the problem of the top floor still occurs or it directly restarts. I have successfully run GRUB when booting from the USB flash drive. Both methods have not loaded any other DOS programs except the built-in command.com

Got it, you mean first run GRUB4DOS, then **boot and run FreeDOS on the emulated virtual disk**, and then there's a failure when entering GRUB. Currently, there's no support for FreeDOS in the emulation state. This function will be added later. Thanks.

Buddy:
The description of GRUB4DOS hasn't been updated for several years, can we write a new description?

Actually, I don't have time to take care of this. Compared with other software, GRUB4DOS has a relatively fast development speed, but the price is the lack of documentation. You have to give up something to gain something. Recently, a foreign friend said that he might write some documentation and tutorials, and I'm waiting for his news. If anyone here is willing to write Chinese tutorials, of course, you are welcome.

Now the relevant documentation of GRUB4DOS is lacking, and some materials in the forum are not uniform, which makes people feel confused. At the current stage, only by practicing more can we distinguish the true from the false.
