Using a USB drive to boot is certainly good, but it must be supported by the motherboard. Many of the machines we are using now (especially low-to-medium-grade laptops) do not have USB ZIP or USB HDD boot options and cannot boot from a USB drive.
And NTFSPRO does not provide a boot-loading driver; it runs after booting and can read and write NTFS partitions, but the partition's location is set later and is no longer its original drive letter. Moreover, it requires two floppy disks to be installed, which is not suitable for a bootable disk.
Brother Shen's DOS 7.1 disk's NTFS support uses a READNTFS read-only NTFS partition program similar to a browser to achieve this. Therefore, it seems that there is no perfect NTFS driver yet, which is also a topic for current DOS programming experts: how to separate the NTFS partition driver from the XP boot program? I am also researching it.
