China DOS Union

There is an old laptop. Sometimes it is used (the CD - ROM is broken, USB boot is not supported, and there are floppy disks); it is troublesome when the system is broken. Now the solution is to remove the hard disk; it is too troublesome.

I. Purpose: Boot the XPE system (the hard disk is small, so the C drive cannot be formatted, and there are files; after the XPE is booted, the system of the C drive is restored, and there is a backup elsewhere)
1. Want to boot the computer with a floppy disk and simultaneously load the USB driver, and the USB flash drive can be used (Note: The loaded USB flash drive can be seen, and the drive letter is C
2. Use GRUB4DOS on the USB flash drive to boot the Lao Maotao XPE system on the USB flash drive (Note: It always cannot be booted)

II. Please explain in detail how to achieve booting the XPE, and using GRUB4DOS on the USB flash drive to boot the Lao Maotao XPE system on the USB flash drive (the more detailed the better)

Is the old machine running out of memory? Try using a DOS image that supports a network MSDOS client.
