Hello everyone. I have read all the Q&As and really gained a lot. Thanks. I have been using USB devices under DOS for a long time. I would like to share some problems and experiences: (I used to have many failures and experiments, but through modification and coordination, I can finally drive them successfully.)
1. For using Teclast flash drives, when plugging in for booting, any bootable disk (including hard disk) cannot boot. How to use it under DOS? Actually, you can insert it when detecting USB devices after booting from a floppy disk.
2. When ghosting a partition to a mobile hard disk under DOS, the speed will be very slow (I spent 2 hours for backup). There is still no good way to solve this problem so far. If anyone has any good ideas, please let me know. Thanks!
