China DOS Union

This is a USB flash drive version of the general PE system. When booting, there are too many options. I just want to keep the DOS and PE options and remove all others. How to modify it?

The uploaded image is too large in size and does not meet the forum's uploaded file type. Moreover, this problem can be completely described in words. Please modify it by yourself, otherwise it will be deleted

Delete it if you want. I don't know what attachment is considered large. Is this 46.87kb png format file very large? Why could it be uploaded if the format doesn't meet the requirements? Now I know why this forum is so deserted

The space of the forum and the upload space of the forum are not the same website. The space of the forum is very tight. If everyone is convenient and uploads randomly with attachments, the forum will soon have a space shortage! And the [Upload] in the upper right corner of the forum and the [Upload File] in the lower right corner when replying to posts are provided by a super moderator of the forum. The space is relatively larger, but the procedures are a little more cumbersome. I hope everyone can understand. Use external links if it is not very necessary. [That is, not forum attachments, such as the upload space of the forum or other external links]

Open:boot, then open cfgsy with Notepad (note that you need to remove the read-only attribute first). Keep these two lines:
menuitem=M2,Boot Mini PE
menuitem=M3,Pure Dos 7.1
