Hello, I have been using the MAXDOS 5.5S version all the time, and I have been using it for several years, but this version can only support a maximum of 2G of memory. Currently, I don't like the latest version of V8. Thank you, boss, for telling me which file to modify so that this version can support more than 2G of memory. Thanks boss for replying!

ERROR 29: Selected item cannot fit into memory
Press any key to continue........

The prompt is this, unplugging one memory stick or having less than 2G can be used!

Is it that GRUB doesn't support more than 2G? Or does HIMEM not support

Updating GRUB, I don't know how to change the paths inside. When using a tool to change it, it always reports an error!

After reading your post, it seems that memdisk doesn't support it. Try using the latest memdisk.

Thanks for your reply. I'm already using the latest memdisk, but it's still the same. I suspect whether I need to change GRUB to support it?

Heheh, upstairs, using the new version of g4d to directly boot the MaxDOS kernel can start normally, which has been confirmed on my 4G memory machine. Of course, trying to boot only by replacing the new version of memdisk has also been confirmed to be not feasible. It seems that it is indeed the problem of the original version of GRUB. You'd better honestly switch to g4d.

Regarding the problem of extracting the MaxDOS kernel, I introduced it in your other post.

Thank you for your reply. I don't know which GRUB is suitable. Can you send one to me?

Why does DOS need such a large amount of memory?
